Publicado em 24 março 2021
A study conducted at the University of São Paulo's São Carlos Physics Institute (IFSC-USP) in Brazil compared the performances of two types of self-assembled monolayers, one consisting of mercaptoacetic acid (MAA) in water and ethanol, and another of 11-mercaptoundecanoic acid (11-MUA) in ethanol. The respective films were evaluated in terms of their capacity to produce sensors for detection of the gene PCA3, which is specific to prostate cancer cells. "We showed that [...]
