The coexistence of biomolecules in the living being blood, and urine plays a crucial function in the biological systems. For i.e., in human organism, generally there coexist Ascorbic Acid (AA) and Dopamine (DA) in the extracellular fluid. Moreover, in the human’s blood and urine, it coexists Uric Acid (UA) and (AA). Therefore, these compounds are of great interest in biomedical function which play a essential factor in the human metabolism, central nervous, renal systems, and beyond. However, abnormal levels of these molecules can lead to a drop-off in the biological system purpose. So, that, since long time ego, as described here, there are many materials in diverse forms that have been designed and developed for both biomolecules oxidation and detection. However, it still some issues to master this concern such the materials costs, the process optimization and cost, the environmental friendliness of the suggested catalysts, and so on. Therefore, there is a higher need in the development of a new and powerful platforms for the early and facile sensing of these biomolecules with cost- effective, high selectivity, as well as best sensitivity, superior stability.

“…This can be uncomfortable, painful, and hard, especially for older patients and children . To the best of our knowledge, noninvasive glucose sensors are not widely available for commercial use despite a recent increase in interest in this technology. − One of the major body fluids used by researchers to develop a glucose sensor is saliva. , Although there is a relationship between salivary and blood glucose levels, measurements are only accurate when taken during fasting, which restricts their applicability to diabetic patients and, consequently, their commercialization. , On another hand, glucose sensors based on interstitial fluids are available for commercial use, , where needle usage was the option to access the interstitial fluids, which penetrate through the skin. These sensors are available and have gained growing acceptance from the market, but they still pose potential risks, such as microbial infection. , Furthermore, there are less invasive sensors that use microneedles to access the fluid. , Each time the sensor penetrates the skin, it can cause a side effect such as swelling .…”

For diabetic patients, effective glucose monitoring is critical, which makes the development of inexpensive, enzyme-free, and nonintrusive glucose sensors necessary. Conventional techniques have not been consistent, necessitating intricate instrumentation and protocols that drive up prices, impede downsizing, and take too long. The presented research attempts to develop a stable Bi 2 O 3 (bismuth oxide)-sensing electrode derived from Bi-BTC [bismuth (Bi)�1,3,5-benzenetricarboxylic acid (BTC)]. This electrode operates through an extended gate field-effect transistor configuration and is designed to facilitate noninvasive glucose monitoring. This electrode exhibits a high sensitivity of 351.68 μA mM −1 cm −2 , a limit of detection of 3.7 μM, and a quick response time of less than 5 s in 1× phosphate-buffered saline, effectively covering a linear range from 20 to 1300 μM. The Bi-BTC-derived Bi 2 O 3 -sensing electrode follows Michaelis− Menten kinetics in response to glucose, with a K m value of 0.86 mM, which is lower than the K m value of 0.89 mM for glucose oxidase, implying that Bi 2 O 3 has strong affinity toward glucose. Most remarkably, we used measurements with a scanning Kelvin probe to show a relationship between the glucose response and the electrode's work function. Additional research using standard artificial sweat has demonstrated the excellent recovery of the Bi-BTC-derived Bi 2 O 3 -sensing electrode. Overall, our findings have shown how well the prepared electrode can quickly detect sweat glucose levels, providing encouraging opportunities for the noninvasive diagnosis of diabetes mellitus.

Here, integrated functional components into a hybrid heterostructure via highly stabilized network‐like interconnected electronic nanoarchitecture of 1D N‐doped holey‐carbon nanotube (NHCNT) with 2D nickel─metal–organic framework (Ni─MOF) nanosheets are developed as high‐performance electrocatalyst for overall water splitting. The NHCNT promoting electron transport pathways in electrocatalyst, and formation of holes in nanotubes further enables excellent diffusion of ions for promoting the overall reaction rate. An excellent combination of 1D/2D structure of NHCNT/Ni─MOF‐4 electrocatalyst exhibits excellent oxygen evolution reaction (η10 = 207.8 mV, and Tafel = 62.6 mV dec−1) and reasonable hydrogen evolution reaction (η10 = 159.8 mV, and Tafel = 107.69 mV dec−1) activity with consistent and stable performance in a 1 m KOH. The highly interconnected network structure contains Ni2+ and Ni3+ species in the NHCNT/Ni─MOF‐4 electrocatalyst, which possesses high specific surface area (SSA) (235.53 m2 g−1), electrochemically active surface area (ECSA) (796.2 cm2), mass activity (4.76 mA mg−1), and turnover frequency (3.99 × 10−2 s−1), which provide remarkable electrocatalytic performance via generating synergy between the NHCNT and Ni─MOF. For overall water splitting, NHCNT/Ni─MOF‐4 attains a low cell voltage (1.77 V@10 mA cm−2).
