Interaction of a helical peptide with membrane: Study of alamethicin
Alamethicin is a transmembrane ion channel at low concentration, and a lytic agent of cell membrane at high concentration. It is a small size polypeptide (20 amino residues), and contains a large section of amphiphilic ...
Illuminating biomolecular interactions with localized surface plasmon resonance
Noble metal nanoparticles exhibit localized surface plasmon resonance (LSPR), in which incident light causes a collective oscillation of a nanoparticle's free electrons. This phenomenon results in unique optical properties, ...
