Nanoparticle labels in immunosensing using optical detection methods

Efficient oxide phosphors for light upconversion; green emission from Yb3+and Ho3+co-doped Ln2BaZnO5(Ln = Y, Gd)

“…[1][2][3] Potential applications of these materials include biosensors, [4][5][6] colour displays [7][8][9] and solar cells. [10][11][12][13] One of the first historical applications of upconverting materials was in the area of solid-state compact lasers 14 emitting in the visible, with important applications in the areas of data storage, reprographics, and underwater optical communications.…”

Magnetic/luminescent core/shell particles synthesized by spray pyrolysis and their application in immunoassays with internal standard

“…In addition, we demonstrate the application of the particles in a new format for a quantitative magnetic immunoassay with an internal luminescent standard. 2 and Nd(NO 3 ) 3 was sprayed into a hydrogen diffusion flame through a nebulizer. The flame was formed by an H 2 flow at 2 l min −1 and an air co-flow at 10 l min −1 , surrounding the outlet of the nebulizer.…”

Advanced AuNMs as nanomedicine’s central goals capable of active targeting in both imaging and therapy in biomolecules

“…The enzymatic degradation of DNA substrate probes was utilized to induce aggregation of AuNPs, so the reproducible and sensitive SERS signals were achieved from biological recognition events. Development of SERS-barcoded particles, which contain multiple Raman-active molecules and are insensitive to photobleaching, is particularly intriguing for high-throughput and multiplex DNA screening [67]. Recently, Chen et al [68] prepared a SERS-barcoded nanosensor to detect Bacillusthuringiensis (Bt) gene transformed rice expressing insecticidal proteins.…”
