Electrochemical sensing of vitamin B (pyridoxine) by adapted carbon paste electrode.

The recent investigation targets to use adapted carbon paste (CP) with copper nanoparticles (CuNs) operating in a phosphate buffer (PBS) medium with a pH range of 5.0-8.0, to synthesize a novel, susceptible, and simple electrochemical sensor for the detection of one of the most important drugs, vitamin B.

Enhanced modified poly-tyrosine voltammetric sensor for the quantification detection of salivary pepsin.

Pepsin as an aspartic acid protease member and one of the three foremost proteolytic enzymes in the digestive system is essential to be detected. An electrochemically polymerized tyrosine film on carbon paste electrode (pTyr/CPE) has been synthesized by electro-polymerization donating an affordable electrochemical sensor to sense salivary pepsin as a diagnostic technique for gastroesophageal reflux disease (GRD) due to saliva collection is non-invasive and relatively comfortable. The pTyr/CPE was applied for Voltammetric sensing of pepsin and its quantification in phosphate buffer solution of pH 2.

Electrochemical, biodegradation and cytotoxicity of graphene oxide nanoparticles/polythreonine as a novel nano-coating on AZ91E Mg alloy staple in gastrectomy surgery.

Graphene oxide nanoparticles/polythreonine polymer as a nano-coating on AZ91E Mg alloy was considered as a new temporary implant for gastrectomy applications. This coating as a novel one is decomposable and has bio-viability possessions. Various electrochemical measurements were utilized for corrosion performance estimation of Mg alloy in peritoneal fluid with time of dipping.

Electrochemical behavior of surgical 316L stainless steel eye glaucoma shunt (Ex-PRESS) in artificial aqueous humor.

A novel system of electrodeposited gold nanoparticles on a carbon paste electrode was utilized as an electrochemical sensor to monitor the corrosion performance of 316L stainless steel alloy in aqueous humor containing moxifloxacin hydrochloride (MFH) drug. Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and potentiodynamic polarization measurements were used to estimate the corrosion performance of 316L stainless steel alloy in aqueous humor with immersion time. The experimental data was confirmed by scanning electron microscopy (SEM), Energy dispersive X-ray analysis (EDX) and antibacterial activity.
