Diabetic foot ulcers are chronic wounds that affect millions and increase the risk of amputation mortality, highlighting critical need for their early detection. Recent demonstrations wearable sensors enable real-time wound assessment, but they rely on bulky electronics, making them difficult to interface with wounds. Herein, a miniaturized, wireless, battery-free monitor measures lactate in seamlessly integrates bandages conformal attachment bed is introduced. Lactate selected due its...
Abstract An ultrasensitive label‐free electrochemical aptasensor was developed for selective detection of chloramphenicol (CAP). The made using screen‐printed gold electrode modified with synthesized nanocube/cysteine. interactions CAP aptamer were studied by cyclic voltammetry, square wave voltammetry (SWV) and impedance spectroscopy. Under optimized conditions, two linear calibration curves obtained determination SWV technique, from 0.03 to 0.10 µM 0.25–6.0 a limit 4.0 nM. has the...
The anodic oxidation of sulphadiazine (SD) was investigated at a glassy carbon electrode modified by multi-walled nanotube (MWCNT–GCE), using cyclic voltammetry and chronoamperometry. results indicate that MWCNT-modified GCEs show an efficient selective electrocatalytic activity towards the SD among biologically important compounds in buffered solutions pH = 7. It found surface MWCNT–GCE occurs potential less positive than unmodified GCE (about 100 mV). diffusion coefficient also estimated...
Abstract The present work explains the fabrication of a novel electrochemical aptasensor for identifying and measuring epirubicin (Epi) by using curcumin (Cur) as an anticancer indicator. prepared immobilizing thiolated aptamer on surface graphite screen‐printed electrode modified with gold nanoparticles/functionalized multiwall carbon nanotubes, ionic liquid chitosan nanocomposite (AuNPs/FMWCNTs‐IL‐Chit/SPE). To evaluate willingness to interaction Epi in presence complementary strand DNA,...
In this study, we design an electrochemical aptasensor with enzyme-free amplification method to detect tryptophan (Trp). For the amplified signal, screen-printed electrode was modified dendritic gold nanostructures (DGNs)/magnetic double-charged diazoniabicyclo [2.2.2] octane dichloride silica hybrid (Fe3O4@SiO2/DABCO) increase surface area as well electrical conductivity, and hemin/G-quadruplex aptamer immobilized. The presence of Trp improved catalytic characteristic structure, which...
Electrochemical DNA biosensors are particularly attractive because of their high sensitivity, suitability and compatibility with miniaturization in nucleic acid technology.
Since many macroalgae are a rich source of antioxidants, in this paper we investigated the antioxidant potential extracts (obtained by microwave-assisted extraction) derived from Gracilaria pygmaea red macro algae collected Persian Gulf coast Bushehr (south west Iran) using voltammetric method as an alternative to spectroscopic methods. The differential pulse (DPV) technique was used evaluate phenolic content, DPPH radical scavenging ability, and then results were compared with For purpose...
