We present a theoretical investigation on possible selection of olfactory receptors (ORs) as sensing components of nanobiosensors. Accordingly, we generate the impedance spectra of the rat OR I7 in the native and activated state and analyze their differences. In this way, we connect the protein morphological transformation, caused by the sensing action, with its change of electrical impedance. ...

The role of palladium surface oxides and adsorbed oxygen in the analytical performance Pd-NPs-based nanobiosensors is ascertained.

Electrochemical techniques have great promise for low-cost miniaturised easy-to-use portable devices for a wide range of applications-in particular, medical diagnosis and environmental monitoring. Different techniques can be used for biosensing, with amperometric devices taking the central role due to their widespread application in glucose monitoring. In fact, glucose biosensing takes an appro...

The rapid and increasing use of the nanomaterials (NMs), nanostructured materials (NSMs), metal nanoclusters (MNCs) or nanocomposites (NCs) in the development of electrochemiluminescence (ECL) nanobiosensors is a significant area of study for its massive potential in the practical application of nanobiosensor fabrication. Recently, NMs or NSMs (such as AuNPs, AgNPs, Fe₃O₄, CdS QDs, OMCs, graphe...

Conventional methods to detect pathogenic microorganisms can be wasteful, expensive, and not very sensitive. Due these limitations, approaches based on nanotechnology the development of new diagnostic tests are emerging as alternative methods. Resulting from unique electrical, magnetic, luminescent, catalytic properties nanomaterials, rapid cost-effective have been developed recognize presence ...

Cancer is one of the most leading cause of death worldwide and can take over 200 diverse forms, including lung, prostate, breast, cervical, ovarian, hematologic, colon cancer, and leukemia. It has been found that environmental factors (eg, alcohol, radiation, smoke, and carcinogenic chemical compounds) as well as genetic factors (eg, autoimmune dysfunction and hereditary mutations) are linked w...
