Spatiotemporal heterogeneity originating from genomic and transcriptional variation was found to contribute to subtype switching in isocitrate dehydrogenase-1 wild-type glioblastoma (GBM) prior to and upon recurrence. Fluorescence-guided neurosurgical resection utilizing 5-aminolevulinic acid (5ALA) enables intraoperative visualization of infiltrative tumors outside the magnetic resonance imaging contrast-enhanced regions.

Enhanced Green Fluorescent Protein (eGFP) shows much stronger fluorescence than its ancestor, Green Fluorescent Protein (GFP), thus has been widely applied as a reporter for biomedical research. In this study, we reported the expression of a synthetic codon optimized gene encoding eGFP in Escherichia coli (E. coli).

In this work, we further develop the obtained IOPC by an embedment of AuNPs to further improve the fluorescence intensity due to the LSPR. With the role of AuNPs in enhancing the fluorescence intensity of the IOPC, this material can be further studied in the field of biological system that might benefit from the added sensitivity afforded by this approach.

Quantitative analysis of glycans released from glycoproteins using high-performance liquid chromatography (HPLC) requires fluorescent tag labeling to enhance sensitivity and selectivity. However, the methods required to remove large amounts of excess labeling reagents from the reaction mixture are timeconsuming.

A rhodamine B derivative containing 1,2,4-triazole as subunit was characterized as an “off–on” type Cu2+ - selective fluorescent probe. It exhibited high selectivity and sensitivity for Cu2+ in ethanol–water solution (9:1, v:v, pH 7.0, 20 mM HEPES) and underwent ring opening. A prominent fluorescence enhancement at 570 nm was observed in the presence of Cu2+ with the change in the absorption spectrum, and a 1:1 metal–ligand complex was formed.

In the present paper, various fluxes assisted Eu3þ doped SrTiO3 nanophosphors were prepared via a solution combustion route. Among all fluxes, NH4F was found to be an appropriate one, which can reduce the forming temperature, improve morphology and enhance the luminescence intensity by two-fold to that of without added flux.

Synthesis of a new (E)-N1-((9-ethyl-9H-carbazol-3-yl)methylene)-5-nitrobenzene-1,2-diamine as a fluorescent chemosensor for selective detection of Fe3+ ion over a number of other metal ions is described. The method for the synthesis of the carbazole Schiff base was based on the condensation of carbazole-3-carbaldehyde with 4-nitro-ophenyldiamine in dimethylformamide in a moderate yield. The structure of the final compound was characterized by 1H NMR, 13C NMR, IR, mass spectrometry, and single crystal X-ray diffraction.

The aminated-silica nanoparticles with a positive zeta potential interact with GFP having a negative zeta potential via ionic force. GFP immobilized by the aminated silica nanoparticles greatly enhances (ca. 2 times) the bioluminescence intensity compared to free GFP. The lipase/aminated-silica nanoparticles catalyzed the transesterification reaction of 1-hexanol and ethyl acetate.

Whole genome sequencing is effective at identification of small variants, but because it is based on short reads, assessment of structural variants (SVs) is limited. The advent of Optical Genome Mapping (OGM), which utilizes long fluorescently labeled DNA molecules for de novo genome assembly and SV calling, has allowed for increased sensitivity and specificity in SV detection.
