Semiconductor nanocrystals as fluorescent biological labels. What are the methods of fluorescent labeling? - Peg Linkers Review Fluorescent proteins are suitable for labeling tumor cells, viruses, genes, etc. Commonly used are GFP, EGFP, RFP (DsRed), etc. Fluorescent dye labeling is the same as in vitro labeling. Cy3, Cy5, Cy5.5 and Cy7 are commonly used, which can label antibodies, peptides, and small molecule drugs. Coupled electrochemiluminescent and resonance energy transfer ... The electrochemiluminescence and resonance energy transfer (ECL-RET) method was adopted to detect miRNAs, in which the two-dimensional Ti3C2 Mxenes with high surface area modified with CdS:W nanocrystals (CdS:W NCs) were used as ECL signal emitter. Mxenes with a specific surface area of 5.2755 m2/g carried more emitters and promote ECL intensity. As an energy acceptor, BiOCl nanosheets (BiOCl ...

Structural dynamics of light harvesting proteins, photosynthetic ... A basic 13 C NMR experiment encompasses single pulse excitation, also termed direct polarization (DP), of the 13 C nuclei (90° pulse) followed by 13 C detection. A drawback of this type of NMR experiment is that 13 C longitudinal T 1 relaxation times for molecules with low internal motions are very long, requiring long recycle delay intervals in between repeated scans.
