Physicochemical Characterization of Azo Compounds
Absorption spectra of all azo derivatives were recorded using a Jasco V-660 spectrometer (Jasco Corporation, Tokyo, Japan) in the 200–800 nm range, at room temperature, in a 1 cm quartz cuvette.
Fluorescence emission of the azo derivatives was measured on powder, using a OceanInsight XDH spectrometer (OceanInsight, Orlando, FL, USA) modular device coupled via optical fiber to a LED source emitting at 365 nm on reflection mode, and in solution using a Jasco V850 spectro-fluorimeter (Jasco Corporation, Tokyo, Japan). FTIR spectra were collected using a Tensor 37 Bruker equipment (Bruker Corporation, Billerica, MA, USA) instrument within the spectral range 400–4000 cm−1, with 32 scans at a resolution of 4 cm−1. Sample pellets were prepared by adding azo dye powder to KBr powder.

Photostability of Curcumin in Pluronic Micelles
The photostability of the drug encapsulated in micelles was investigated using changes in fluorescence emissions after exposure to blue light. Curcumin in different Pluronic micellar solutions (0.2 μg/mL) were prepared as described earlier. Samples were placed in a quartz cuvette (1 cm optical pathway) and excited at 470 nm using the optical system of the above-mentioned spectrofluorimeter for 5, 15, 30, and 45 min, and the fluorescence spectra were recorded. The amount of undecayed CURC was calculated using the equation:

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
