Abstract:Here, we report a threshold limit value (TLV) of on-chip cytotoxicity of Nepali Chiya, the Nepali traditional black tea. To demonstrate our proof-of-concept validation, we used the active sealing chip with serial dilution that can directly perform on-chip cytotoxicity testing onto the cells cultured in a petri dish. In our experiments, the TLV for mortality on HeLa cells was observed as 400 μg/ml for Nepali Chiya extract. We believe this approach would be a rapid and simple method for on-chip TLV screening of … 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.
