Neurotransmitter release is important to study in order better understand neurological diseases and treatment approaches. Serotonin a neurotransmitter known play key roles the etiology of neuropsychiatric disorders. Fast-scan cyclic voltammetry (FSCV) has enabled detection neurochemicals, including serotonin, on sub-second timescale via well-established carbon fiber microelectrode (CFME). However, poor chronic stability biofouling, i.e., adsorption interferent proteins electrode surface upon...
We report on the fabrication of ZnO nanorod (NR)-based flexible piezoelectric nanogenerators (PENGs) carbon paper (CP). Structural investigations indicate that NRs grew well along porous CP surface. Optical investigation shows crystal quality was comparable to grown Si substrate. As molar concentration increased from 10-70 mM, output voltage and current consistently 3.6-6.8 V 0.79-1.45 μA, respectively. The enhancements were attributed enhanced accumulation potentials generated by number in...
In this paper, an annular spoof surface plasmon polariton (SSPP) based metamaterial inspired terahertz (THz) sensor has been designed. The geometry exhibits three different modes depending upon the frequency changes from 0.7-2 THz due to variation of dielectric constant external biological material. simulated and analyzed in full-wave simulator fabricated laboratory. obtained sensitivity is 550 GHz/RIU with figure merit 5.5. proposed SSPP-based paves way possible uses biochemical sensing...
Analysis of trace level metals in environmental samples (e.g., soil, water, and plant samples) is important for assessing quality food safety. This paper reports a non-toxic, eco-friendly, cost-effective sensing method, capable in-situ detection microgram per liter (µg/L) levels heavy metal ions soil solutions using carbon fiber electrodes (CFEs) produced without any microfabrication. The electrochemical behaviors the CFEs were characterized by cyclic voltammetry (CV) impedance spectroscopy...
This paper reports a non-toxic, eco-friendly, and cost-effective sensing method to detect microgram per liter level of localized heavy metal ions in vegetable plant agricultural soil solutions using glass encapsulated carbon fiber microelectrode (CFME).As proof principle, CFMEs were tested for selected metals buffer as well differential pulse anodic stripping voltammetry (DP-ASV).Preliminary results confirm that the able measure mercury (Hg), lead (Pb), cadmium (Cd) with detection limit 10...
