{"data":{"id":45,"name":"Time-resolved fluorescence emission spectroscopy","abbreviation":"TRFS","description":"<p>Time-resolved fluorescence spectroscopy (TRFS) is a powerful method for probing the dynamic molecular environment within lipid bilayers. By measuring fluorescence intensity decay, TRFS reports on local polarity, hydration, viscosity, and the presence of quenchers or energy acceptors near a fluorophore. This makes it highly valuable for studying membrane structure, dynamics, and organization, often revealing information inaccessible to steady-state measurements. TRFS can identify membrane domains, quantify lipid mobility, characterize peptide\u2013membrane interactions, and distinguish leakage mechanisms using lifetime changes. Its sensitivity and ability to capture nanosecond-scale processes make TRFS a key technique in biomembrane research.<\/p>","categories":[{"id":167,"title":"Positioning","breadcrumb":[{"id":4,"title":"Experimental"},{"id":167,"title":"Positioning"}]}],"url":"https:\/\/molmedb.upol.cz\/api\/v1\/methods\/45","landing_page":"https:\/\/molmedb.upol.cz\/method\/45","created_at":"2019-05-06T11:03:55.000000Z","updated_at":"2026-07-08T08:29:28.000000Z"}}
