Thank you
شكراً لكم
Thanks for this episode. I have a few comments about some projects based on the PoC implementation as more details revealed.
- 3D touch authentication: I still believe in faceID as an easier way to be integrated into systems with minimum training procedure. Depending on the pressure data is an obsolete solution as Apple for example removed this 3D touch feature from its own devices. Other resistive 3D touch screens are not accurate and not commonly used.
- Bones fractures scanning: Using NIR to detect bones fracture is a promising technology but not with any existing sensors. The radiation can't go through skin and reach bones. Neospectral has failed to achieve any practical application, I know some companies using it went down because its resolution and stability is not good. I still see the thermal camera is a better/cheaper option if you can get the best setup.
- Active Headrest for cars: I think this idea is going into the wrong direction. The headrest movement should be vertically (up down) not (front back) which is crazy dangerous!! I don't understand how did u miss such an important issue like this!
- Organ-on-Chip: I'm a bit disappointed for this project. I expected to see some high resolution biochip with a cutting edge implementation roadmap. What I can see is a just a simple DIY PDMS chip that is done by a hobby guy. I would advise you to check the latest technologies of manufacturing these chips (check this startup: www.emulatebio.com/)
The current trends for manufacturing biochips include microfluidic pumps for insertion and drug delivery(while you use a very manual way), PVD and semiconductor chip manufacturing (while you use a low resolution CNC), sense-on-chip which is absent in your design. However, the domain is very interesting for me.
Good luck
Fruitful input
I don’t know about the other projects, but I know about Wadah’s project “The organ-on-chip guy”. We used to work in the same lab together for years, and we had some deep conversations about his invention.
I’m not an expert in what he is doing, but based on information he published and our discussions about his project, I'll highlight a few things that address your comments.
Novel features: (copied from his page):
The novelty of his chip is that he could “form inside of it ultra-thin porous walled cylindrical polymeric ducts that are 0.5mm in diameter and with a wall thickness of just 7um and pore sizes of 8um, features and aspect ratios that are impossible to be created using current manufacturing technologies”. “Most of current organ-on-chip manufacturing processes use lithography to cut through PDMS surfaces or use CVD to depose materials forming the needed features, those techniques are surface based, they can form 3D surfaces but never full 3D structures like the one described above”. The way he manufactured those chips was kept a secret, but what I know is that the chassis holding the duct is manufactured using CNC machining that according to him has enough resolution for this application. Higher precision techniques would be more expensive to use at this stage and would offer little advantage (he proved that the project has a tolerance in the micron range, so using nm techniques would not bring much). We had a few discussions about scaling up his design for mass production though.
Novelty importance: (copied from his page):
Those polymeric ducts created inside the chip could be accessed from the inside and outside through different microfluidic channels to insert the cells accordingly. The duct acts as scaffolding system to guide the cells to attach and form the circular cross-sectional epithelial cell lining that could form lumen as it does in the body. And the duct is coated to become biologically inert not effecting the cell’s natural expression and to increase cell adhesion. In addition, the duct could be accessed from the inside to create the myoepithelial and epithelial tissues and from the outside to create the stromal tissue. The pore size is big enough to allow for the cells squeezing and passing if signaled to do so and small enough to prevent its leakage to the other side when pumped micro-fluidically.
The main advantages of his chip is that it could provide the following:
1) circular cross-sectional scaffold (curvature): Cells when attached to the inner surface of the duct, and getting confluent, it can achieve a membrane polarity (differentiation) resembling natural tissues.
2) Co-culture with the surrounding stroma: regardless to the stiffness of the stroma, it can be easily grown to surround the cylindrical epithelial tissue forming the duct.
3) few steps seeding: Cell seeding isn’t dependent on the gel; cells can be pipetted into duct & stroma channel in few easy steps.
Competitive advantage: (copied from his page):
“Comparing out my chip to the top direct competitors and key-market players:
1) Nortis: was the only company capable of creating accessible cylindrical ducts with controlled geometries. However, they form their tissues in gels, which are mechanically unstable especially when trying to mimic diseases with low stiffness matrices, such as cancer (surrounding the stiff tumor). Many diseases that are common in ductal organoids cannot be modelled using this chip, in addition that the usability of this chip is very manual and not scalable.
2) Emulate: that created the famous breathable lung on chip, the formed tissue is mechanically stable, accessible, allow coculture, but doesn't replicate the 3D circular structures of neither the alveoli nor the blood capillary. It should be noted that in ductal organoids the cylindrical structure is of high importance on the cellular expression (polarity, membrane differentiation markers and lumen formation)
3) Mimitas: is another interesting company, using their phase guide technology, they were able to rapidly and easily coculture different tissues on the same chip, however the cocultured tissues aren't structurally mimetic.”
I worked with Waddah on a previous project in which we considered many sensing techniques for bioreactor/LOC applications. I know that his design is intended to easily incorporate sensing techniques. He also used to use micro-fluidic syringe and peristaltic pumps for his chip in our lab, so from what I know his chip could be connected to a pump.
In addition that from what he recently posted on his Facebook page: (copied from his Facebook page):
“One small note for the technical people:
In the proof-of-concept I didn't only work on finite element analysis (FEA) simulations, The main work was on computational fluid dynamics (CFD) simulations, which was a very hard task since I was simulating microfluidics in a porous media and with variant aspect ratios, and redesigning the chip accordingly!! I never could've done this without stars-of-science and the experts support as we did around 320 simulations and iterations in a period of 3 weeks only!! Many thanks for everyone who helped me during this stage!!”
I believe the purpose of the CFD campaign in his work is to optimize the Mico-pumping flow parameters for different biological applications. The flow is certainly not just fed through a pipette in his design :p
@@nicolasabdelkarim4052 Thanks for your detailed reply. Sorry I didn't know these info about this project since I just saw a simple CNC and a simple hot laminating/pressing tool (assuming to join 2 surfaced machined plates)
I got more interested to see what's uniqueness he is bringing from micromachining and bio-engineering points of view.
I have some experience in thinfilm/MEMS production and I've created a machine that utilizes the latest PVD technologies to make thinfilm based chips on scale. I've created also my own 2 guns for lithography (FIB & picosecod fiberlaser).
Talking about some claims: you said "form inside of it ultra-thin porous walled cylindrical polymeric ducts that are 0.5mm in diameter and with a wall thickness of just 7um and pore sizes of 8um, features and aspect ratios that are impossible to be created using current manufacturing technologies”
I don't see why current technologies can't do this. Have you seen the complicated MEMS structures that companies build on chips these days? It's away more complicated than the mentioned features because of intended micro-movement. You can always use PVD technologies to grow layers and even seal them to create the other layers without externally laminating or gluing layers (that's something from the past). You can even grow nanoporous material if you use the right PVD tool/material.
I don't see why do you think current technologies can't do " a full 3D structure".
Do you have a whitepaper or a link with more information about this project? I will keep following it through the next episodes. You have only compared the OOC with existing gel-matrix and limited 3D scaffolds but how do you compare it with a nano-scale structure like "The Next Generation Nanoculture" plate ?
@@abedb007 To be honest, i'm not up to date with waddah's latest findings. My last conversation with him about this was more than a year ago, but he puts information about this all over the place, I copy/pasted the above from his facebook account.
My expertise is in catalysis, so I'm not an expert in manufacturing but I know the challenges he tried to solve include creating 3d microstructures with well-defined micro porosities with difficult materials and geometries. I also think that mechanical strength of the structures and the dependency of a flat surface to cut through or build on from one side only is a limitation in current processes.
I'm not sure what you mean by nanoculture, as cells and organoids in this application are in the micrometer scale. (each cell is in 10s of um in size, an organoid is in the 100s of um range).
Scaling down the natural size of organoids defies the purpose, even the idea of using a Nano-manufacturing technology for this also defies the purpose.
From his page:"... Ductal organoids culture currently have many limitations especially in terms of structure, multi-cellular assembly, component buildup and mechanical stability...", and I think that this is what the OOC culture is all about, it is not about scaling down to the smallest possible, it is scaling down to the smallest functional cellular organization possible. in the link you attached above (www.emulatebio.com), creating a simple co-culture across a flat microporous surface was a breakthrough.
There are so many breakthroughs to be made in this field.
@@nicolasabdelkarim4052 I agree that many breakthroughs can be made into this cutting edge domain. I like this idea and I'm just curious to see if it's better than anything exist and why. So far it's my favorite one this year in SOS.
I don't see any serious challenges with the mentioned manufacturing problems. I've worked on complicated structures before using EDM 5 axis machine, trust me u can produce very complicated molds with sub micro resolution. Anyway, I would love to see the new microstructure to decide if it can be done or needs a new machinery method which I doubt.
Regarding the nano-structure I sent, it's not to grow cells through but to grow cells over it and eliminate the need of special gel or scaffold. The cells will be free to move over this nano plate (can't be attached to the nano grid) without any external material or gravity force involved. That would result in a better proliferation than other 3D technologies. Please refer to this link: www.infinitebio.com/products/scivax_3d-cell-culture/index.html
