ESR was measured by a microspectrophotometer
with the stopped flow technique (Alifax).
An SD2000 microspectrophotometer
(Bioprince, Atlanta, GA, USA) was used to determine RNA concentrations.
The electronic absorption spectra were measured in five zones of the films with an UV-Vis-NIR microspectrophotometer
(MSP500RT, Angstrom Sun Technologies) within 400-1000 nm with a 40x objective and spot size of 10 [micro]m; an FTO substrate was used as reference.
CRAIG Technologies has added Raman mi-crospectroscopy to its 20/30 Perfect Vision microspectrophotometer
