摘要:
Fluorophores derived from photoactivatable azide-pi-acceptor fluorogens or from a thermal reaction of an azide-pi-acceptor fluorogen with an alkene or alkyne are disclosed. Fluorophores derived from a thermal reaction of an alkyne-pi-acceptor fluorogen with an azide are also disclosed. The fluorophores can readily be activated by light and can be used to label a biomolecule and imaged on a single-molecule level in living cells.

Sub-micron objects are manipulated. According to an example embodiment of the present invention, Brownian motion effects are mitigated to facilitate the analysis and/or manipulation of sub-micron objects. In some applications, an electric field is applied to facilitate the manipulation of sub-micron objects in solution, facilitating the analysis of the manipulated objects. In other applications, fluid flow is used to effect the manipulation of sub-micron objects in solution.

The present disclosure relates to an apparatus, and methods of use, for enhancement of molecular emission by nano-antennas. Using the nano-antennas, the life-time is greatly shortened or the strength of broadly peaking spectral emission of fluorescent molecules is greatly enhanced by a generated electric field. The electric field generated is due to opposing charges located at two metallic end portions of the nano-antenna in response to receiving optical energy.
