Oral cancer poses a serious threat worldwide owing to its soaring case-fatality rate and metastatic characteristics of spreading the other parts body. Despite recent breakthroughs in biomedical sciences, detection oral at an early stage is still challenging. Conventional diagnosis clinics optical techniques detect initial stages are quite complicated as well not completely accurate. To enhance survival patients, it important investigate novel methodologies that can provide faster, simpler,...
A noninvasive electrochemical melanoma detection approach based on using adhesive tapes for collecting and fixing cells from a suspicious skin area transferring the into scanning microscope (SECM) is presented. The layer collects reproducibly keeps them well adhered tape during experiments in an electrolyte solution. biomarker, here intracellular enzyme tyrosinase (TYR), was imaged tape-collected without further cell lysing antibodies that were labeled with horseradish peroxidase (HRP). HRP...
Scanning electrochemical microscopy (SECM) is one of the scanning probe techniques that has attracted considerable attention because its ability to interrogate surface morphology or reactivity. However, quality SECM images generally depends on sizes electrodes and many uncontrollable factors. Furthermore, manipulating fragile glass ultramicroelectrodes blurred sometimes frustrate researchers. To overcome challenges modern SECM, we developed novel soft gold probes then established AI-assisted...
Scanning electrochemical microscopy (SECM) offers a highly sensitive and convenient approach for mapping of interleukin-6 (IL-6), an oral cancer protein biomarker. In this study, we utilized the SECM to map distribution IL-6 imaging different stages on tissue sections. The results indicated that was expressed higher in tissues as compared normal hence, can be employed improve diagnosis. Also, analysis beneficial predicting severity COVID-19 at early stage eliminate potential risks serious...
Abstract In recent years, graphene, two-dimensional closely packed honey-comb carbon lattice, has been attracting much attention in the field of electrochemistry due to its intrinsic properties and merits. Moreover, nickel found extensive use preparation biosensors. present study, we applied a simple straightforward approach for development nanoparticle-graphene sheet (NiNP-GS) modified glassy electrode (GCE) nonenzymatic biosensor applications. The nanocomposites NiNP-GS with various...
This paper evaluated the use of soft-probe scanning electrochemical microscopy complementarily with confocal laser to study effects different antimicrobial agents and treatments on E. coli DH5α biofilm. The were sodium azide, silver nanoparticles, a flashlight. these monitored by measuring change in biofilm properties, such as biomass, live/dead studies, surface activity. results showed that flashlight effectively killed biofilms explained mode action for each treatment. Sodium azide was...

Scanning electrochemical microscopy (SECM) is a scanning probe technique that composed of micro- or nanoelectrode can be scanned in close proximity to an interface. Faradaic current signals recorded due the flux redox active species between sample and amperometric SECM probe. used image topography reactivity biological specimens for mapping localized biochemical activity. Although has been applied different systems, studies tissues are still under exploration. The reason shape high roughness...
Here, the semi-invasive direct electrochemical detection of melanoma biomarkers in non-treated skin has been envisaged. The enzyme tyrosinase (TYR) was to be addressed with a microneedle sensor. microneedles were fabricated by polydimethylsiloxane (PDMS) casting stable polymers. as-prepared (MNs) then coated gold sputtering. MNs finally covered alginate/catechol provide liquid electrolyte layer that contained electroactive species, such as catechol, whose redox state can linked concentration...
