Ascorbic acid is a vital biomolecule for human beings. When the body’s level of ascorbic acid is abnormal, it can lead to a number of illnesses. Its appropriate concentration is necessary for the oxidation of prostaglandins and cyclic adenosine monophosphate, the production of dopamine, norepinephrine, epinephrine, and carnitine, and the expansion and durability of the collagen triple helix in humans. In the present work, silver nanoparticle synthesis was performed through a paracetamol-mediated approach. Different characterization techniques, such as X-ray diffractometry (XRD), energy dispersive X-ray (EDX), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM), were used to confirm the prepared nanoparticles. Subsequently, the prepared Ag NPs functionalized with an ionic liquid were used as a sensing platform for ascorbic acid in blood serum samples. To achieve the best possible results, the proposed biosensor was optimized with different parameters such as TMB concentration, time, amount of capped nanoparticles (NPs), and pH. The proposed biosensor offers a sensitive and straightforward method for ascorbic acid with a linear range from 2 × 10–9 to 3.22 × 10–7 M, an LOD of 1.3 × 10–8 M, an LOQ of 4.3 × 10–8 M, and an R 2 of 0.9996, Moreover, applications of the proposed biosensor were successfully used for the detection of ascorbic acid in samples of human plasma, suggesting that Ag NPs with high peroxidase-like activity, high stability, and facile synthesis exhibited promising applications in biomedical fields.

“…Notably, the intensity of the (110) peak significantly surpasses that of the other peaks in the XRD pattern. This pronounced intensity suggests that the (110) crystal plane plays a dominant role in the overall diffraction behavior of the TiO 2 layer . The presence of crystalline TiO 2 in the sensing layer is of particular significance and allows for better charge transport and stronger interactions with gas molecules during the sensing process.…”

Through-silicon via (TSV) technology is used to produce a TiO 2 gas sensor. The conical TSV structure is constructed using a laser with a wavelength of 1064 nm, and the depth-to-diameter ratio is 20:13 (200 μm: 130 μm). The sensing layer TiO 2 is fabricated by using a thermal oxidation (TO) process and covers the TSV structure. X-ray diffraction and energy-dispersive X-ray spectroscopy analysis show that the main plane of the TiO 2 film is (110), and there is a uniformly covered TSV structure. For the TiO 2 gas sensor operating at room temperature (RT) of 25 °C, the recorded sensor responses are 12.08, 15, 18.5, 23.9, 31, and 38.9%, corresponding to NO 2 concentrations of 0.25, 0.5, 1, 2, 5, and 10 ppm. In assessing the stability, the sensing result registers 18.5% over three cycles at 1 ppm of NO 2 , with a deviation under ±0.2%. The TiO 2 material exhibits better selectivity for NO 2 than for other gases (NH 3 , CO 2 , CO, H 2 , H 2 S, and SO 2 ). The results of this study show that the RT TiO 2 gas sensor with a TSV structure is stable, reversible, and exhibits good selectivity for NO 2 gas.
