A Highly Sensitive and Selective Surface-Enhanced Nanobiosensor
Nanosphere lithography (NSL) derived triangular Ag nanoparticles were used to create an extremely sensitive and specific optical biological and chemical nanosensor. Using simple UV-vis spectroscopy, biotinylated surface-confined Ag nanoparticles were used to detect streptavidin down to one picomolar concentrations. The system was tested for nonspecific binding interactions with bovine serum alb...
متن کاملAptamer-based highly sensitive electrochemiluminescent detection of thrombin via nanoparticle layer-by-layer assembled amplification labels.
The preparation and use of a new class of signal amplification label, the CdTe quantum dot layer-by-layer assembled polystyrene microbead composite, for amplified ultrasensitive electrochemiluminescent detection of thrombin is described.
متن کاملA NOVEL AND HIGHLY SENSITIVE CATALYTIC METHOD FOR THE DETERMINATION OF ULTRA TRACE AMOUNTS OF CERIUM WITH SPECTROPHOTOMETRIC DETECTION
Cerium (IV) has a catalytic effect on the very slow redox reaction between gallocyanine and bromate in acidic media. The reaction was monitored spectrophotometrically at 525 nm by a fixed time method of 4.0 rnin from initiation of the reaction. The decrease in absorbance at 525 nm is proportional to the Ce (IV) concentration in the range of 0.005-1.000 and 1.00-10.00 pg. ml-l. The limit of ...
متن کاملCreation of an aptamer nanobiosensor for ultra-sensitive detection of heart failure
This study focuses on discovering a new aptamer sequence that binds specifically and with high affinity to brain natriuretic peptide (BNP), which is indicative of the early stages of heart failure. A library of random DNA sequences was generated synthetically, amplified by the polymerase chain reaction (PCR) and evaluated for specific binding to BNP using an in vitro selection technique known a...
متن کاملHighly Sensitive Amperometric Sensor Based on Gold Nanoparticles Polyaniline Electrochemically Reduced Graphene Oxide Nanocomposite for Detection of Nitric Oxide
A sensitive electrochemical sensor was fabricated for selective detection of nitric oxide (NO) based on electrochemically reduced graphene (ErGO)-polyaniline (PANI)-gold nanoparticles (AuNPs) nanocomposite. It was coated on a gold (Au) electrode through stepwise electrodeposition to form AuNPs-PANI-ErGO/Au electrode. The AuNPs-PANI-rGO nanocomposite was characterized by Field Emission Scanning ...
