Light Matters . . . 35 Years of New Sources for Spectroscopy

July 20, 2020

On the occasion of Spectroscopy’s 35th birthday, I thought it would be an interesting opportunity to consider the amazing explosion in light sources for spectroscopy over the last few decades.

The Rise of the Upconversion Materials

January 01, 2020

An important class of nanoparticles made of “upconversion” materials has found a central role in sensing. These nanoparticles are used to convert longer-wavelength photons into shorter-wavelength fluorescence to detect temperature, pH, gas molecules, ions, and trace biomolecules.

Advances in the Applications of Lasers for Bioimaging: Light Sheet Microscopy

October 01, 2019

Lasers allow advances for investigation of biological samples. Discussed here are some of the most interesting recent developments in light sheet microscopy for bioimaging, including a technique that allows for unique viewing of large, intact samples including biopsies.
