Time-resolved FRET fluorescence spectroscopy of visible fluorescent protein pairs [PDF]

open access: yes, 2010
Förster resonance energy transfer (FRET) is a powerful method for obtaining information about small-scale lengths between biomacromolecules. Visible fluorescent proteins (VFPs) are widely used as spectrally different FRET pairs, where one VFP acts as a ...

A superior bright NIR luminescent nanoparticle preparation and indicating calcium signaling detection in cells and small animals

open access: yesCell & Bioscience, 2018
Background Near-field fluorescence (NFF) effects were employed to develop a novel near-infrared (NIR) luminescent nanoparticle (LNP) with superior brightness. The LNP is used as imaging contrast agent for cellular and small animal imaging and furthermore
