I've been testing several aproaches to getting a stable close-packed array of 518 and 617 nm nanospheres at the milipor subphase surface, for a future Langmuir Blodgett implementation. From what I've seen, I can't get another result than its precipitation. I've tried both adding NaCl to the subphase, centrifugating, and testing other nanospheres solvents, such as diacetone, ethanol and chloroform. Is there any suggestion or lab procedure that could improve my work? Thank you for your time! ;)
Thanks a lot for your tips, Luis. I haven't been able to return to the lab since the COVID situation started but I hope to do so whenever things get back to the normal. I've had a bit of success while trying a small amount of SDS (around 0,02 mMol/L) as surfactants in the aqueous subphase, which tend to improve the interface dispersion. Do you have any knowledge of such applications?
