Surface enhanced fluorescence immuno-biosensor based on gold nanorods

Strategies Employed to Design Biocompatible Metal Nanoparticles for Medical Science and Biotechnology Applications

“…Plasmonic NPs also exhibit the capacity to enhance signal intensity through mechanisms such as Förster resonance energy transfer (FRET) and surface-enhanced Raman spectroscopy (SERS), both based on the LSPR of mNPs. − The quenching and enhancing properties of plasmonic NPs, juxtaposed with fluorophores positioned in their proximity, are often exploited in fluorescence-based biosensors and cell imaging.…”

“…Nanomaterial engineering allowed the development of new platforms and materials for different fields such as energy, catalysis, optics, and medicine. The tunable geometric, optical, and surface properties of organic and inorganic nanomaterials, particularly nanoparticles (NP), allow the creation of unique physical and chemical characteristics, like multifunctionality of the surface, multivalence, and the ability to carry large molecules. , These features lead to several applications, such as diagnostics, − imaging, − electrochemical sensing, − photothermal therapy, , controlled releasers, and theranostics …”

One-step assembly of TA-FeIII supramolecular shell on AgNPs surface for regulating fluorescence intensity of quantum dots

“…© 2023 The Japan Society of Applied Physics I n the past 40 years, surface enhanced fluorescence (SEF) has become one of the main detection methods in medical diagnosis and biotechnology. [1][2][3][4] SEF technology can easily detect individual molecules, and fluorescence detection is a highly sensitive technology, but there is still a trend of reducing the detection limit. 5,6) Metal nanoparticles have excellent surface plasmon resonance properties, which induce local electromagnetic field enhancement through local surface plasmon resonance (LSPR), thereby stimulating fluorescent molecules near the nanoparticles to enhance fluorescence.…”
