Abstract:This paper reports a handy technical scheme to decorate
atomic
force microscopy (AFM) tips toward tip-enhanced Raman spectroscopy
(TERS) applications. The major attraction of these homemade tips lies
in that silver decoration can be confined at the apex of commercial
tips by the means of an AFM-controlled electrochemical reaction. The
reduction of Ag+ occurs in a highly sealed environment
to secure the metal coating efficiency. Key factors include silver
nitrate solution to provide Ag+, ambient relative humidi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
