The individual is involved in the comprehensive evaluation of phytochemicals for various bioactivities, employing a wide range of techniques and methodologies. The evaluation spans diverse fields including diabetology, cancer biology, inflammation, oxidative stress, toxicology, animal reproductive biology, antiviral activities, hepatoprotection, intestinal absorption, immunomodulation, plant-animal interaction, and targeted drug delivery using nano particles. The techniques employed include animal cell culture, Western blotting, gene expression studies, cell signaling studies, in vitro and in vivo evaluations of phytochemicals, short-term and long-term toxicity assessments, in vitro evaluation of anti-viral activity, next-generation sequencing (NGS) and transcriptome analysis, radioactive incorporation assays, various microscopic techniques, flow cytometry, electron microscopy, spectroscopy (FT-IR, UV-Vis, circular dichroism), plate readers, rheometer, and scintillation counter. This multi-faceted approach reflects a comprehensive investigation into the pharmacological potential and mechanisms of action of phytochemicals.
