Sentence examples for fluorescent entity from inspiring English sources

The combination of a magnetic and a fluorescent entity may provide a new two-in-one multi-functional nanomaterials with a broad range of potential applications.

There is a great necessity for the development of these multifunctional nanocomposites, but there are some difficulties and challenges to overcome in their fabrication such as quenching of the fluorescent entity by the magnetic core.

Porphyrin derivatives have also been employed by Gu et al. [53] who have reported the preparation of porphyrin-functionalised magnetite nanoparticles using catechol chemistry to provide a covalent link between the magnetic cores and the fluorescent entity (Fig. 9). Figure 9 Direct covalent linkage of magnetite nanoparticles to dopamine functionalised porphyrin.

We anticipate that Trp residues would become oxidized after exposure to UVB-light because of the absorbance spectrum of Trp in the near UV region, the fluorescence studies demonstrating loss in intrinsic Trp emission (Figure 6A) and the formation of a new fluorescent entity (likely NFK, Figures 6C).

This means that closely spaced labeled proteins (closer than 250 nm) appear as a single fluorescent entity when viewed through the microscope.

The focus of this review is the association of magnetic and fluorescent entities.

There have also been several reports of magnetic nanoparticles and QDs encapsulated within a polymer or silica matrix, allowing for the preparation of fluorescent entities which can be manipulated by an external magnetic field [34 36].

Two types of lipid-based magnetic contrast agents, one based on gadolinium and fluorescent entities combined in a bilipid layer and the second on a hydrophobic iron oxide nanoparticle in a fluorescent lipid-containing micellular shell, have been prepared by van Tilborg et al. [45].

Dimerization of the tagged proteins reconstitutes the full-length, folded fluorescent or luminescent entity and leads to an optical readout.

The aim of this review is to present an overview of bimodal "two-in-one" magnetic-fluorescent nanocomposite materials which combine both magnetic and fluorescent properties in one entity, in particular those with potential applications in biotechnology and nanomedicine.

The synthetic linker may be attached to a variety of entities such as fluorescent dyes and solid supports, permitting labeling of fusion proteins in cell lysates for expression screening, and efficient capture of fusion proteins onto a purification resin.
