摘要:Abstract(#br)The fluorescence quenching of CdSe/CdS core/shell quantum dots (QDs) with various shell thicknesses is investigated. Inducing aggregation of the core/shell QDs with the addition of NaCl shows that the fluorescence quenching efficiency decreases monotonically as ...

摘要:Abstract(#br)We report simultaneous detection of the variants 3a and 3b in the oncogenic EML4–ALK fusion gene using cDNA from lung cancer patients based on energy transfer between CdSe/ZnS quantum dots (QDs) and gold nanoparticles (AuNPs). To overcome the limitations of the ...

摘要:Abstract(#br)We have developed a simultaneous detection method for two common mutations in the epidermal growth factor receptor gene based on the fluorescence quenching phenomenon caused by aggregation of CdSe quantum dots. For detection of the in-frame deletion in exon 19 and th...

摘要:Abstract(#br)We have investigated the reduction of silver ions in a gold nanoparticle suspension by dihydroxybenzene isomers: hydroquinone (1,4-dihydroxybenzene), catechol (1,2-dihydroxybenzene), and resorcinol (1,3-dihydroxybenzene). We found that using these isomers as red...

摘要:Abstract(#br)Aggregation effects of gold nanoparticles (AuNPs) were examined for the discrimination of single point mutations through the hybridization of oligonucleotides (25–50 nM) modified with a fluorescent Texas red dye. The sequences of oligonucleotides were designed t...

摘要:Abstract(#br)We have detected mutations in the epidermal growth factor receptor (EGFR) of non-small cell lung cancer cells using the selective aggregations of gold nanoparticles. Mutations in exon 19 and exon 21 of EGFR gene were detected in non-amplified genomic DNAs that were i...

摘要:Abstract(#br)Silver nanoparticles (AgNPs) are one of the most commonly used nanomaterials due to their antibacterial properties. In this study, we examined the effects of polyvinylpyrrolidone (PVP)-coated AgNPs (average size 2.3 nm) on angiogenesis in both an in vivo model and an...

摘要:Abstract(#br)Because of the limited information on size-dependent particle-mediated effects, the present study was conducted to determine if the changes in induced protein expression between 5 nm silver nanoparticles and 100 nm particles after exposure to sub-lethal concentration...

摘要:Selective energy transfer between quantum dots and gold nanoparticles was used to simultaneously detect mutations in the epidermal growth factor receptor (EGFR) gene. We functionalized the surface of gold nanoparticles and green and red-emitting quantum dots using four different ...
