Novel red-to-NIR fluorophores called Nanchang Red (NCR) dyes have been constructed by rational structural hybridization of cyanine and borondifluoride curcuminoid. The peculiar asymmetrical layout the three key fragments endows these long-wavelength with ideal photophysical properties ER self-targeting capability. photoluminescent mechanism, revealed quantum chemical calculations, will greatly ...

We wish to describe certain simplifications in the technique previously described (13, 14) for the purification of prothrombin and thrombin. With new adaptations it is possible to process large quantities of plasma and at the same time to obtain products 2 to 5 times as potent as those previously reported from this laboratory. A brief survey of the chemical properties of these newly obtained pr...

A novel white light-promoted reaction using photoluminescent nanocrystalline silicon enables the hydrosilylation of alkenes and alkynes, providing stabilization of the porous silicon without significant loss of the photoemissive qualities of the material. Photopatterning and lithographic fabrication of isolated porous silicon structures are made possible. Experiments and observations are presen...
