Background/Objective: In-vivo diabetes detection of glucose were sought using square-wave anodic stripping voltammetry (SW), with bismuth-immobilized carbon nanotube paste electrode (BCE). Methods: The optimum analytical results indicated sensitive peak signals on the BCE. The raw voltammogram was approached within the 1 mgL^-1-14 mgL^-1 and 10 ugL^-1-140 ugL^-1, detection limits with preconcentration times of 100 and 200 sec. Results: The relative standard deviation was 0.02 % (n = 15) of 10.0 mgL^-1 under optimum conditions. The analytical detection limit (S/N) was attained at 8 ugL^-1. The handmade microsensor was directly used in vivo on the living fish brain and human urine.Conclusion: The method was applied at real time in vivo, without requiring any pretreatment and other ionic electrolyte solutions. It can be used for medicinal and other materials requiring biological-fluid detection in real time. This study was designed to be suitable for real-time unmanned remote diagnosis and therapeutic drug injection into the body, micro-needle long-term administration, wearable artificial skin tattoo sensor, and real-time control. In addition, the glasses monitor was designed to be suitable for multitasking and multi-user control.

Biomolecular detections of Helicobacter pylori(HP) were compared using specially modified sensors and fluorine immobilized on a carbon nanotube (HFCNT) electrode, which yielded sensitive results. Handheld voltammetric circuits were used for optimization. An anodic voltammogram of HP molecular oxidation was obtained at 0.0 V (versus the Ag/AgCl/KCl) in a 0.1M NH4H2PO4 electrolyte solution. Under optimized conditions, the analytical working range was 2.98x103-22.127x103 CFU/ml HP using square wave (SW) stripping voltammetry, precision of R2 =0.9857 (SWSV), the detection limit approached to 2.5x102 CFU/ml HP (S/N=3).The developed techniques have been applied to diagnosis of early-stage HP infections using stomach tissue from healthy humans and gastric patients.

Pandemic human influenza detections are dependent on complex, time-consuming DNA molecular amplifications that require sophisticated PCR electrophoresis, cell culture amplification and complex spectrophotometric absorption techniques. In this study, simplified rapid electrochemical sensing methods were sought via a remote cyclic voltammetry and stripping amplifier circuit using our workstation systems. A sensing probe was prepared using human DNA and a Covid 19 antigen immobilized antibody sensing amplifier with rapid accumulation time of 30 sec. Optimal experimentation was performed using a telematics WiFi wearable circuit equipped with a bioelectrochemical analyzer-2 amplifier three electrode system. Diagnostic accumulation voltammetry and cyclic redox scanning were attempted at -2.0V~2.0V potential windows and 0.2V/Sec scan rate. Anodic and cathodic real time assay was performed using saliva swab from female patients that tested negative and positive. Diagnostic results are expected to be useful for non-contact analysis and for rapid personal testing anytime, anywhere.
