Applications of Fluorescence Resonance Energy Transfer (FRET) in biology have expanded tremendously the last 25 years. This technique has become a staple many biological and biophysical fields. FRET based chemical sensors biosensors can play an important role as biomarkers. Development new effective assay for application is emerging area research needing multidisciplinary approach from biologis...

in this study, the adsorption of 4-hydroxy phenyl-azobenzene on the surface of (4, 0) zigzag open-end boron nitride nanotube (bnnt) has been investigated by quantum calculations. in order to find the preferred adsorption site, different positions and orientations were considered. the impacts of donor-acceptor electron delocalization on the structural and electronic properties and reactivity of ...

Venus is a recently developed, fast maturating, yellow fluorescent protein that has been used as a probe for in vivo applications. In the present work the photophysical characteristics of Venus were analyzed spectroscopically at the bulk and single molecule level. Through time-resolved single molecule measurements we found that single molecules of Venus display pronounced fluctuations in fluore...

Abstract We derive expressions for pion photoproduction amplitudes in the 1/Nc expansion of QCD, and obtain linear relations directly from this expansion that relate electromagnetic multipole amplitudes at all energies. The leading-order relations in 1/Nc compare favorably with available data, while the next-to-leading order relations seem to provide only a small improvement. However, when reso...

A new fluorescent probe with a unique sequential dual FRET process was designed and constructed. This probe showed distinguished responses towards Fe(3+) and Hg(2+), making it an ideal candidate for multiple logic operations at the molecular level.

We report a detailed study of the pairing resonance via tunneling density of states in ultrathin superconducting Al films in supercritical magnetic fields. Particular emphasis is placed on the effects of the perpendicular component of the magnetic field on the resonance energy and magnitude. Though the resonance is broadened and attenuated by H(perpendicular) as expected, its energy is shifted ...
