Can i have more info about the dimensions of the channels?

Is it advisable to use a vacuum pump in order to quickly remove the air bubbles in the PDMS?

looks like they used one. propably it is. i thought the very same watching this.

Amazing!

cool! how many more times can the printed design be casted? or doesit disinttegrate aftyter first cast?

It's one print per cast. Once you cast, it solidifies over time. Then you can wash off the channels.

Thank you for the feedback. Glad this was useful.

Really interesting

Man, I'm just trying to figure out how colors mix to produce different colors, like is it linked to turbulance and if so is it a chemical reaction, or an optical illusion.

The color is based on the pH of the fluid. I think they used one universal pH indicator for both samples. So, when they change color, they change due to a chemical reaction.

can I get a paper from your research?

Love it, omg you really make sounds so easy. New Subscriber.

Hi can you send me a quotation of prices of the reagents you used? PDMS, Fpluronic, ... or even redirect me to someone who could do so. thanks a lot

Are the channels exposed to the open air on the bottom face?

Yes we use tape to cover the channels so you have a seal to flow fluids through. Otherwise you can use a glass slide.

Any recommendations on how to attach the PDMS device onto a glass slide ? Any help is much appreciated

Just make sure both surfaces are clean and dry before attaching the glass slide onto the PDMS cast. Good luck!

You have to go for O2 plasma etching of the glass slide after which you bond it with the PDMS

can you please send us the dimension or STL file to me

Pluronic 127 for creating the mold / channels

why dont they just completly 3D print the end product in plastic? with channels built in?

depending on the kind, but fdm is out because of the porosity , i don't know for resin printing but i guess you'd need something chemically inert , as for slm/sls, it's probably feasible yet would be an expensive piece of equipment

This is not microfluidics. This is millifluidics. Nice video and technique anyway.

Yes you are absolutely correct. More for demo and educational purposes.

Not very "micro", though!
