on the immobilized SARS‐CoV N protein on the surface of a glass chip. Detection is based on the optical signal variation of a QDs‐supported RNA aptamer interacting on an immobilized protein chip. Using an optical QDs ...
of highly sensitive and selective sensor systems . It also points out the salient features and importance of aptasensors in the detection of mycotoxins along with the different immobilization methods ...
samples. The E2-ovalbumin conjugate (E2-OVA) was covalently immobilized onto the optical fiber as a biorecognition element as well as a transducer. The affinity constant of the E2/ aptamer complex ...
for thrombin detection . The aptamer raised against thethrombin was immobilized through an electrostatic immobilization method, using poly-L-lysine as cationic polymer. Thefunctionalized probe was characterized ...
been manufactured using standard single-mode fibers on CO2 laser splicing system . Further, the resonator of diameter 518 µm has been calibrated with sucrose for refractive index changes with optical ...
highlight a general method to tailor an aptamer sequence in two subunits that are randomly immobilized into a layer of polymer brushes grown on the internal surface of microfluidic channels, optically aligned ...
of BPA with high sensitivity and selectivity. In this system , the probe DNA molecule, which is the complementary sequence of a small part of the BPA aptamer , was covalently immobilized onto the optical ...
An interferometry-based method was developed for detection of a small molecule, argininamide. The quantification of argininamide was demonstrated using aptamers immobilized on silicone oxynitride ...
(FET) platform. Higher affinity of the aptamer probes to PA in the aptamer ‐ immobilized FET enables significant improvements in the limit of detection (LOD), dynamic range, and sensitivity compared ...
. The test microfluidic system was arranged as a flow through a massive of four working chambers for immobilization of peptide aptamers , coupled with the optical detection system , based on thick film ...
