An ultrasensitive label free human papilloma virus DNA biosensor using gold nanotubes based on nanoporous polycarbonate in electrical alignment

Electrochemical virus detections with nanobiosensors

“…Impedimetric HPV DNA biosensor by AuNTs-polycarbonate electrode was fabricated. Biosensor in label-free detection showed the good linear ranges of 0.01À1 mM [114].…”

“…EIS has enlighten at surface area and interaction modification agents and the electrode surface [113]. Because of occurrence of an electrochemical reaction at the electrode surface upon interaction with target molecule, impedance biosensors have been widely used for the environmental monitoring of disrupting chemicals and drugs, interaction between antibody and antigen, and DNA strains [114]. The EIS measurement studies the dielectric parameters of a biological system in wide frequencies.…”

“…The EIS measurement studies the dielectric parameters of a biological system in wide frequencies. The EIS provides information about surface adsorption, ion exchange, diffusion, and charge transfer [114].…”

Carbon Nanodot–Based Fluorescent Method for Virus DNA Analysis with Isothermal Strand Displacement Amplification

“…As known, the ability to detect a single biomolecule is important for clinical diagnosis at the early stage of infection . Fast and accurate methods for virus detection are urgently needed to control the spread of the viruses …”

Electrochemical investigations for COVID-19 detection-A comparison with other viral detection methods

“…Lee et al [178] developed an electrochemically based label-free avian influenza virus detection method using multi-functional DNA structure on a porous (p) AuNPs-modified electrode. The proposed DNA 3 way-junction/pAuNPs based detection method can be applied for multiple-target detections as a valuable biosensor for determining the pathogen subtype in one platform or one target detection using the dual detection method with high reliability.…”
