Effective Multistep Exciton Delivery Through DNA-based Photonic Wires

Spillmann C.M., Buckhout-White S., Ancona M.G., Cunningham P.D., Melinger J.S., Goldman E.R., Medintz I.L., Naval Research Laboratory, US

Energy manipulation at the nanoscale is a key requirement to develop next-generation nanotechnologies ranging from biosensing to light harvesting, yet the design rules of these nanoscale systems must first be optimized to accomplish their intended [...]

230 fold fluorescence enhancement by 3D Rhodamine B coated polystyrene photonic crystals

Eftekhari E., Li Q., Li X., Cole I.S., Li Q., Li X., Griffith University, AU

We report a 230-fold fluorescence enhancement with fluorescent polystyrene based three-dimensional (3D) colloidal photonic crystals (F-CPhCs) that can be readily fabricated over large areas. A simple and reproducible method was developed to synthesise novel fluorescent [...]

Investigation of secondary electron emission of a monocrystal diamond for creation microchannel devices with high quantum efficiency

Sadovoy V., Terentiev S., Bormashov V., FSBI TISNCM, RU

In this work possibility of use of a monocrystal diamond(CVD and HPHT) as highly effective secondary emitter is shown.The maximum SE coefficient about 14 at working accelerating voltage is received (several times exceeds SE coefficient [...]

FIRMS: A Novel Technique for Magnetic Molecular Imaging

De Silva L., Hu Q., Wang Y., Xu S.-J., University of Houston, US

Molecular imaging usually employs a labeling technique, mainly optical labeling or magnetic labeling, to highlight target molecules. While optical labeling uses a wavelength parameter to achieve molecular specificity, there is no analogous parameter in magnetic [...]
