In this study, an oxidation treatment technique suitable for the material and electronic device applications proceeding at low temperature (only 80 degrees C) and high pressure (3000 psi) utilizing a carbon dioxide (CO2) supercritical fluid (SCF), also known as scCO(2), which is supplemented with water molecules, is reported. To demonstrate the possible effects on material and devices for the proposed SCF treatment, an amorphous germanium-sulfur (GeS) thin film and a GeS-based resistance random access memory (RRAM) device are prepared. After the SCF treatment, electrical measurements confirm that the GeS-based RRAM device exhibits a lower forming voltage, more stable resistance switching characteristics, and higher concentration distributions of high and low resistance states when compared to the device without SCF treatment. As for the material effects, both chemical and physical properties are examined based on material analyses results. It is concluded that the original amorphous GeS thin film transforms to a polycrystallized GeO film, confirmed by a reaction model for the SCF treatment illustrating possible oxidation and crystallization effects induced by this SCF treatment. This water-enhanced scCO(2) SCF treatment technique, thus, shows its capability as a feasible synthetic method for material modification as well as suitability for device level applications.

The development of efficient sensing element for rapid and sensitive measurement of glutathione is important on early detection of human diseases. Herein, we introduce the V2O5 nanosheets (NS) as a novel nanozyme to biomimic the oxidase activity toward the rapid detection of glutathione. The 5-6 layered V2O5 NS with 300-600 nm in size is successfully fabricated by ultra-sonication assisted exfoliation of bulk V2O5 using N, N-dimethyl formamide as the intercalation reagent. The sensing mechanism involves the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) by V2O5 NS with the concomitant increase in absorption intensity. Upon introduction of glutathione, the oxidized TMB is converted back to its original form and results in the simultaneous decrease in peak intensity at 650 nm. The sensor exhibits a good linear response to glutathione in the range of 10-500 nM with a limit of detection of 2.4 nM. Moreover, the V2O5-TMB sensor exhibits a good selectivity and high specificity, which makes the detection of glutathione applicable in diluted human serum samples. Since no functionalization of the V2O5 NS is required, this sensing system can open a new avenue to serve as an efficiently biomimic oxidase for glutathione detection in biological fluid samples.
