Published in Biosensors & bioelectronics
In this work, we report the development of a general strategy for enhancing the efficiency of target capture in immunoassays, using a bifunctional fusion protein construct which incorporates a substrate-anchoring moiety for the high-abundance immobilization of an antigen-binding domain. This approach was informed by the development of a pseudo firs...
Spiral shape microfluidic channel for selective isolating of heterogenic circulating tumor cells.
Published in Biosensors & bioelectronics
Detecting heterogenic tumor cells that are traveling in our body through blood stream for the tumor metastasis is one way for cancer prognosis. Due to the heterogeneity of circulating tumor cells (CTCs), further identification of tumor cell types should be accompanied with CTCs isolation from blood cells in peripheral blood sample. Both negative en...
Antifouling aptasensor for the detection of adenosine triphosphate in biological media based on mixed self-assembled apt...
Published in Biosensors & bioelectronics
Direct detection of targets in complex biological media with conventional biosensors is an enormous challenge due to the nonspecific adsorption and severe biofouling. In this work, a facile strategy for sensitive and low fouling detection of adenosine triphosphate (ATP) is developed through the construction of a mixed self-assembled biosensing inte...
Electrochemical immunosensor with nanocellulose-Au composite assisted multiple signal amplification for detection of avi...
Published in Biosensors & bioelectronics
A sensitive sandwich-type electrochemical immunosensor was developed for the detection of avian leukosis virus subgroup J (ALV-J), which benefitted from multiple signal amplification involving graphene-perylene-3,4,9,10-tetracarboxylic acid nanocomposites (GR-PTCA), nanocellulose-Au NP composites (NC-Au) and the alkaline phosphatase (ALP) catalytic...

Published in Biosensors & bioelectronics
A lossy mode resonance (LMR) based sensor for urinary p-cresol testing on optical fiber substrate is developed. The sensor probe fabrication includes dip coating of nanocomposite layer of zinc oxide and molybdenum sulphide (ZnO/MoS2) over unclad core of optical fiber as the transducer layer followed by the layer of molecular imprinted polymer (MIP)...
A shape-code nanoplasmonic biosensor for multiplex detection of Alzheimer's disease biomarkers.
Published in Biosensors & bioelectronics
Alzheimer's disease (AD) is a neurodegenerative disease associated with the loss of nerve cells in the brain. The disease is affected by multifactorial pathways and leads to changes in related biomolecular levels as AD progresses. Therefore, AD should be diagnosed with combined detection of several lesions to improve accuracy. Amyloid beta 1-40, 1-...

Published in Biosensors & bioelectronics
A novel electrochemiluminescence (ECL) immunosensor for ultrasensitive detection of carcinoembryonic antigen (CEA) was developed using signal amplification strategy based on poly(5-formylindole)/reduced graphene oxide nanocomposite (P5FIn/erGO) and Au nanoparticle (AuNP) decorated graphene quantum dots (GQDs) ([email protected]). As an effective matrix for...
Specific bioanalytical optical and photoelectrochemical assays for detection of methanol in alcoholic beverages.
Published in Biosensors & bioelectronics
Methanol is a poison which is frequently discovered in alcoholic beverages. Innovative methods to detect methanol in alcoholic beverages are being constantly developed. We report for the first time a new strategy for the detection of methanol using fluorescence spectroscopy and photoelectrochemical (PEC) analysis. The analytical system is based on ...
