Journal ArticleDOI

Ultra-small fluorescent metal nanoclusters: Synthesis and biological applications

Li Shang, +3 more
- 01 Aug 2011 - 
TL;DR: In this article, the authors summarize synthesis strategies of water-soluble fluorescent metal nanoclusters and their optical properties, highlight recent advances in their application for ultrasensitive biological detection and fluorescent biological imaging, and finally discuss current challenges for their potential biomedical applications.
Journal ArticleDOI

A quantitative fluorescence study of protein monolayer formation on colloidal nanoparticles.

Carlheinz Röcker, +6 more
- 01 Sep 2009 - 
TL;DR: In this article, the authors quantitatively analyzed the adsorption of human serum albumin onto small polymer-coated FePt and CdSe/ZnS nanoparticles by using fluorescence correlation spectroscopy.
Journal ArticleDOI

EosFP, a fluorescent marker protein with UV-inducible green-to-red fluorescence conversion

Jörg Wiedenmann, +7 more
- 09 Nov 2004 - 
TL;DR: A gene encoding a fluorescent protein from the stony coral Lobophyllia hemprichii has been cloned in Escherichia coli and characterized by biochemical and biophysical methods and is found to be tetrameric, with strong Forster resonance coupling among the individual fluorophores.
Journal ArticleDOI

Surface Functionalization of Nanoparticles with Polyethylene Glycol: Effects on Protein Adsorption and Cellular Uptake

Beatriz Pelaz, +9 more
- 25 Jun 2015 - 
TL;DR: Even though the P EG coatings did not completely prevent protein adsorption, the PEGylated NPs still displayed a pronounced reduction of cellular uptake with respect to bare NPs, which is to be expected if the adsorbed proteins are not exposed on the NP surface.
Journal ArticleDOI

Differential Uptake of Functionalized Polystyrene Nanoparticles by Human Macrophages and a Monocytic Cell Line

Oleg Lunov, +11 more
- 23 Feb 2011 - 
TL;DR: The data show that the amount of internalized nanoparticles, the uptake kinetics, and its mechanism may differ considerably between primary cells and a related tumor cell line, whether differentiated or not, and that particle uptake by these cells is critically dependent on particle opsonization by serum proteins.
