I want to facilitate cell attachment to the interdigitated electrode that made with Au/Ni and epoxy with gelatin.however my advisor in believes that gelatin doesn't attach to the substrate and you should treat the substrate with the plasma.has anyone had any experience like this?
The effect of plasma treatment on the gas sensing properties of screen-printed single-walled carbon nanotube (SWCNT) pastes is reported. The gas sensors, using SWCNT pastes as a sensing material, were fabricated by photolithography and screen printing. The SWCNT pastes were deposited between interdigitated electrodes on heater membrane by screen printing. In order to functionalize the pastes, they were plasma treated using several gases which produce defects caused by reactive ion etching. The Ar and O(2) plasma-treated SWCNT pastes exhibited a large response to NO(2) exposure and the fluorinated gas, such as CF(4) and SF(6), plasma-treated SWCNT pastes exhibited a large response to NH(3) exposure.
m thank you, Muhammad. Indeed in my case the electrodes are gold and I am worried about side effect of plasma, like gold etching
Hi Amir,
without knowing what type of plasma and plasma source you have, I can tell you that you will probably encounter only sputtering from your Au electrode because gold is chemically inert, so etching should not be an issue.
