Sensing Proteins with Luminescent Silica Nanoparticles

Langmuir, 2009
Nanometer sized silica nanoparticles (SiO2-NP) were prepared in water and loaded with two organic compounds, namely perylene and 1,6-diphenyl-1,3,5-hexatriene, which have well-defined and known fluorescence properties. The size of void and dye-doped SiO2-NP were determined by both transmission electron microscopy and atomic force microscopy, which ...

Genetically engineered luminescent proteins in biosensing

SPIE Proceedings, 2006
Luminescent proteins originally isolated from marine or terrestrial organisms have played a key role in the development of several biosensing systems. These proteins have been used in a variety of applications including, immunoassays, binding assays, cell-based sensing, high throughput screening, optical imaging, etc.

Artificial luminescent protein as a bioprobe for time-gated luminescence bioimaging

Chemical Communications, 2011
An artificial luminescent protein, apoferritin-encapsulated luminescent europium complex, has been designed/fabricated and displays good biocompatibility and long-lived luminescence, which means it can be used as a bioprobe to image living cells with a time-gated mode.

Confinement-Enhanced Luminescence in Protein–Gold Nanoclusters

The Journal of Physical Chemistry Letters, 2020
Confinement has profound effects on protein functions. Nanoscale probes for confinement or excluded volume interactions could help us understand how these interactions influence protein functions. This work reports on the increased luminescence of BSA-gold nanoclusters when confined.

Phage-based technologies for highly sensitive luminescent detection of foodborne pathogens and microbial toxins: A review.

Comprehensive Reviews in Food Science and Food Safety, 2022
Foodborne pathogens and microbial toxins are the main causes of foodborne illness. However, trace pathogens and toxins in foods are difficult to detect. Thus, techniques for their rapid and sensitive identification and quantification are urgently needed.

Thermally Stimulated Luminescence in Powdered Soy Proteins

Journal of Food Science, 2013
Abstract Heating powder isolated soy proteins (ISPs) in a N 2 environment produced thermally stimulated luminescence (TSL), in 2 major temperature regions, 50 to 250°C (region R1) and 250 to 350°C (region R2).

Engineering of Highly Luminescent Lanthanide Tags Suitable for Protein Labeling and Time-Resolved Luminescence Imaging

Journal of the American Chemical Society, 2004
The synthesis of a new ligand LH(4) based on a glutamic acid skeleton bis-functionalized on its nitrogen atom by 6-methylene-6'-carboxy-2,2'-bipyridine chromophoric units is described. UV-vis spectrophotometric titrations revealed the formation of 1:1 M:L complexes with lanthanide(III) cations, and complexation of LH(4) with equimolar amounts of ...
