Effects of vinyl substitutions on resonance Raman spectra of (bacterio)chlorophylls [PDF]

, 1994
Soret resonance and Qy preresonance Raman spectra are reported and compared for a series of (bacterio)chlorophylls. Chlorophyll a, 2-acetylchlorophyll a, bacteriochlorophyll a and 2-vinylbacteriochlorophyll a were studied in the non-protic solvent ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Theoretical Raman spectroscopy study of finite and infinite fullerene chains inside single-walled carbon nitride nanotubes

Materials and Devices, 2019
We investigated the hybrid system between Nitrogen doped Single Wall Carbon Nanotubes (N-SWCNT) and fullerene (C60  C70) molecules. The structure of the encapsulated fullerenes inside N-SWCNTs is derived from minimum energy calculation using a ...
