Huge upconversion luminescence enhancement by a cascade optical field modulation strategy facilitating selective multispectral narrow-band near-infrared photodetection. [PDF]

Light Sci Appl, 2020
Since selective detection of multiple narrow spectral bands in the near-infrared (NIR) region still poses a fundamental challenge, we have, in this work, developed NIR photodetectors (PDs) using photon upconversion nanocrystals (UCNCs) combined with ...

Modulation of Apoptosis As a Therapeutic Strategy [PDF]

The Scientific World Journal, 2001
Cell death is a contributing factor in many human diseases. A significant proportion of the cell loss that occurs in tissue or organ injury and disease is by programmed cell death, or apoptosis. Apoptosis is a genetically controlled form of cell suicide effected by specific gene products acting within dying cells.
