Design of Stimuli‐Responsive Cobalt Tetraphenylporphyrinate‐Chitosan Microspheres for Advanced Biosensors

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 3, January 21, 2026.
We report on new cobalt tetraphenylporphyrinate‐chitosan‐based microspheres developed for biosensing and anticancer therapy applications. We analyzed their second‐harmonic generation (SHG) behavior using a high‐resolution SHG microscope. In addition to the typical porphyrinate fluorescence, the microspheres exhibit a high‐intensity SHG response and ...
