How do I make Si/Si3N4 surface more hydrophilic?

12 March 2015 1 9K Report

I am trying to prepare lipid bilayer membrane by fusing small unilamellar vesciles on Si3N4/Si. Major goal of this research is to probe the physical and chemical properties of lipid membrane using AFM and FRAP analysis.

Also suggest some methods for treating SUV with hydrophilic surface. This would help me alot to make final lipid bilayer membrane of about 6 - 8nm.

Carlos Domínguez

You can treat the surface of silicon or silicon nitride with an alkali, sodium hydroxide solution type. Depending on time/temeprature of the treatment you get surfaces with different oxidized grade.
