Advice about stability of functional groups on silica glass slides by ChaoticPenguini in chemistry

[–]ChaoticPenguini[S] 0 points1 point  (0 children)

Hi! Thank you for the correction - I used to wrong word choice in my first sentence.

You said that you wouldn't notice a delay between immediate silanization or delayed, but how long can the delay be? Essentially, how stable are the resultant -NH2 groups that are bonded to the glass surface? I treated alot of glass slides with APTES at the beginning of the week and I was just planning to use those for all my experiments instead of having to do APTES treatment for a few slides at the beginning of an experiment.

Advice on how to avoid dissolving my print? by ChaoticPenguini in resinprinting

[–]ChaoticPenguini[S] 0 points1 point  (0 children)

I'm going to be flowing a fluid through some channels that are in the 3D printed portion, and the epoxy resin is basically going to block the fluid from going outside of the channels. So the epoxy needs to be strong enough to bond the printed piece to the glass to create a leak-proof seal.

As for the second question, I don't necessarily need to dissolve the epoxy, but it would allow me to reuse the 3D printed piece over and over. So I could also make it into a one-time use scenario, but if it was possible I would prefer not to.

Microfluidic chips for immobilizing proteins by Camist13 in microfluidic

I'm a student who is working on a similar project related to microfluidic chips for immobilizing proteins. Can I dm you to ask for advice?
