By a News Reporter-Staff News Editor at Energy Weekly News -- Investigators discuss new findings in Nanocrystals. According to news reporting out of Jinan, People's Republic of China, by VerticalNews editors, research stated, "A fluorophore-phenylamine derivative (L) has been coupled with silver nanocrystals (NCs) to construct an L-Ag nanohybrid. Owing to synergic effects of the L and Ag components, the exciton-plasmon interactions between L and Ag increase the strength of the donor-acceptor interaction within the nanohybrid, a fact that results in an energy-transfer process and further brings about a dramatic redshift of single-photon absorption and fluorescence, and a decreased fluorescence FL lifetime."
Our news journalists obtained a quote from the research from Shandong University, "The coupling effect also leads to enhancement of a series of nonlinear optical properties, including two-photon-excited fluorescence (TPEF), two-photon-absorption (TPA) cross section (), two-photon-absorption coefficient (), nonlinear refractive index (), and third order nonlinear optical susceptibility (((3))). The enhanced two-photon fluorescence of the nanohybrid is proven to be potentially useful for two-photon microscopy of live cells, such as HepG2."
According to the news editors, the research concluded: "Moreover, cytotoxicity tests show that the low-micromolar concentrations of the nanohybrid do not cause significant reduction in cell viability over a period of at least 24h and should be safe for further biological studies."
