Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Spectral characterization of three wearable electronic ultraviolet radiation dosimeters

Photochemistry and Photobiology, EarlyView.
Excessive exposure to ultraviolet radiation poses significant public health risks, including DNA damage and skin‐related pathologies. Wearable electronic UV dosimeters enable accurate studies and quantification of solar UV‐radiation exposure on an individual level. Due to variations in the spectral distribution of solar radiation, the spectral mismatch
