Fluorescent silicon nanocrystals for bioimaging
… to produce colloidally stable and brightly fluorescent dispersions, with PL quantum yields in the range of 3.2% - 6.6%. Hydrophilic Si nanocrystals capped with a ligand containing a terminal carboxylic acid group could be directly dispersed in aqueous environments with quantum yields of up …

Fluorescent Materials for Chemical Sensing
Materials incorporating fluorescent π-electron conjugated molecular species for sensing and imaging are advantageous over other detection or identification methods such as colorimetric reporters. Fluorescent materials offer easy recognition of binding events due to the highly sensitive nature of …

Fluorescent sensors for metal ions
The considerable current interest in the use of fluorescent molecules in molecular recognition is not new, but is one that has increased in importance in recent years due to their applications in many fields including trace analysis in chemistry and biochemistry. Using the "dual fluorescence" …

The photophysics of fluorescent protein chromophores
Fluorescent proteins of the Green Fluorescent Protein (GFP) family are important and versatile scientific tools used in a range of applications including the labelling of proteins, cells and tissue, high resolution imaging and studying protein-protein interactions. They exhibit a very diverse range …

Single label fluorescent derivatization of peptides
A one step method for the attachment of a single fluorescent label to peptides through their N-terminus is described. The method employs fluorescein-5-isothiocyanate as the label of choice and a lower than normal derivatization buffer pH that discriminates against $\varepsilon$-amino derivatization …

A thermally stabilized fluorescent organic chromophore
<p>A fluorescent chromophore, hereby designated as cyanine dye, has been bound to generated zinc oxide nanoparticles. It has been shown that the material not only retains the characteristic absorption peak of the native chromophore, but it also continues to fluoresce with comparable intensity. The …

Fluorescent Modifications of Transfer Ribonucleic Acids
… and that, at least to some extent, products with fluorescent properties similar to those of (mu)-guanosine are formed. The primary site of modification has been rigorously identified as either the X-nucleoside or the 7-methylguanosine in the variable loop of tRNA('Phe). The modified tRNA('Phe) can …

Capacitive sensing with a fluorescent lamp
This work presents a modified fluorescent lamp that can be used as a capacitive sensing system. The lamp sensor measures changes in the electric fields emitted from the fluorescent bulbs in order to deduce the presence and motion of conductive and dielectric objects below the lamp. The prototype …

Fabrication and applications of fluorescent polymer fibres
… through electrospinning have been used as fluorescent explosives sensors. Polystyrene fibres containing m-MTDATA were found to improve sensing efficiencies over films with thinner fibres producing the highest efficiencies due to an improved surface-area-to-volume ratio. Furthermore, the …

Novel Fluorescent Sensors for Dynamic Intracellular Signalling
… such experiments. This thesis presents a novel fluorescent reporter for PKC activity in living cells. The kinase C probe (KCP-1) consists of a PKC specific substrate sequence that is flanked by two fluorescent proteins, which are capable of fluorescence resonance energy transfer (FRET). The …

The Fundamental Photophysics of Fluorescent Carbon Nanodots
Carbon Nanodots (CDs) are a new protagonist of carbon-based nanoscience by which the paradigm of carbon as a black material unable to emit light has been completely revolutionised. They have been emerging as a new frontier in Nanoscience at the beginning of 2000s, and their potential is evident …

Theranostic applications of fluorescent liquid crystalline nanoparticles
… antineoplastic drugs and imaging probes for fluorescent optical in vitro and in vivo imaging. We developed cubosome formulations loaded with antineoplastic drugs and useful for the fluorescence imaging of cells. Such formulations were also actively targeted to cancer cells and coupled with a …

Fluorescent materials for short-wave infrared imaging
Our understanding of the fundamental processes that drive biology and medicine is, in large part, based on our ability to visualize biological structures and monitor their transformations over time. Fluorescence imaging is one of the most transformative technologies of modern biomedical imaging as …

Green fluorescent protein as a mechanical sensor
… structure dynamics. To this end, the green fluorescent protein (GFP) is considered as a mechanical sensor candidate with many desirable characteristics. Implicit solvent molecular dynamics CHARMM simulations demonstrated details inaccessible by AFM and OT methods, such as the linkage …
