Investigators at Hanyang University Describe Findings in General Chemical Research (Chemically-Modulated Photoluminescence of Graphene Oxide for Selective Detection of Neurotransmitter by "Turn-On" Response)

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on General Chemical Research is the subject of a report. According to news originating from Ansan, South Korea, by NewsRx correspondents, research stated, "Designing artificial nanomaterials capable of selectively detecting targets without the use of expensive and fragile antibodies is of great interest in the applications of nanomedicine. Here, we show that the photoluminescence (PL) of graphene oxide (GO) was chemically modulated for the selective detection of a neurotransmitter without the use of antibodies."

Our news journalists obtained a quote from the research from Hanyang University, "GO was functionalized with nitrotriacetic acid (NTA) on which four different metal ions were chelated (M-NTA-GO), which led to its different PL responses to neurotransmitters. In particular, the Cu-NTA-GO hybrid was able to selectively detect norepinephrine at nanomolar concentrations in a simple manner via its 'turn-on' PL."

According to the news editors, the research concluded: "Moreover, it was successfully applied to the selective detection of norepinephrine secreted from living PC-12 cells."
