Poly(ethylene glycol) diacrylate (PEGDA) is generally used for various biological applications e.g., bioassays and sensing applications. PEGDA particles fabricated by microfluidics generally uses photopolymerization. However, both PEGDA 575 (molecular weight 575) and PEGDA 700 (molecular weight 700) are reported in the literature.
Is there any difference between polymerization rate of PEGDA 575 and PEGDA 700 ?
Does PEGDA 575 and PEGDA 700 show any difference with EDC/NHS protocol for functionalization?
Is it true for the same amount of photoinitiator (PI) and the same duration of UV polymerization (time=t), e.g., PI= 4% and t= 1 s?
Why both should be inert? EDC/NHS is used frequently for PEGDA functionalization.
Some references mentioned change in porosity for PEGDA575 and PEGDA700. Many other groups used higher mw peg to increase porosity in PEGDA. I guess degree of polymerisation has something to do with the porosity and reactivity.
My point is what happen when we expose them for same duration ?
I got your point.
What about polymerization rate of PEGDA 575 and PEGDA 700 ?
