Cocrystals Enhance Biopharmaceutical and Antimicrobial Properties of Norfloxacin

Pharmaceutics, 2023
A solvate cocrystal of the antimicrobial norfloxacin (NFX) was formed by using isonicotinamide (INA) as a coformer with the solvent evaporation technique. The cocrystal formation was confirmed by performing solid-state characterization techniques.

Pixelated colorimetric nucleic acid assay

Talanta, 2020
Conjugated polyelectrolytes (CPEs) have been widely used as reporters in colorimetric assays targeting nucleic acids. CPEs provide naked eye detection possibility by their superior optical properties however, as concentration of target analytes decrease, trace amounts of nucleic acid typically yield colorimetric responses that are not readily ...
