About

My research involves enhancing the specificity and activity of photosensitizers (PS) using antimicrobial peptides (AMPs) and cell-penetrating peptides (CPPs) as targeting agents. My focus is on the mechanisms of bacterial inactivation achieved by the PS-AMP conjugate eosin-(KLAKLAK)2. We have found that conjugating a soluble PS (eosinY) to a selective AMP provides effective photokilling of bacteria without damaging human cell lines or red blood cells, unlike other hydrophobic PS used clinically.
