A novel cell-based biosensing platform (Large-scale Homogeneous Nanoelectrode Arryas, LHONA) is developed using a combination of sequential laser interference lithography and electrochemical deposition methods. This enables the sensitive discrimination of dopaminergic cells from other types of neural cells in a completely non-destructive manner owing to its enhanced biocompatibility and excellent electrochemical properties. As such, this platform/detection strategy holds great potential as an effective non-invasive in situ monitoring tool that can be used to determine stem cell fate for various regenerative applications.
Intracellular and extracellular formation of Au and Ag NPs with different sizes and shapes using human cells has been developed as green method, which does not require the use of any reducing agents. Also, the cell lysis is used for production of different metal NPs. Our results demonstrate that treatment of human cells with various metal ions cause cell fixation.
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.
