Summary: Electrochemically deposited ZnO nanoparticles on a pencil graphite electrode coated with graphene provide a highly conductive and selective electrochemical sensing electrode for cortisol estimation. Various spectroscopic and microscopic techniques were used for surface morphological analysis, while XRD and FTIR were employed for structural characterization. The DPV analysis showed a linear range of 5 x 10(-10) M - 115 x 10(-10) M with a low limit of detection value of 0.15 nM, demonstrating excellent functionality for salivary cortisol determination at low concentrations.

Summary: In this study, one-dimensional Zn2GeO4 rods were successfully grown in-situ on Ni foam using a hydrothermal route, with ethylenediamine playing a critical role. The Zn2GeO4/NF electrode was found to exhibit high sensitivity, wide linear detection range, low detection limit, excellent selectivity, and stability towards H2O2, attributed to factors such as the intrinsic nature of Zn2GeO4, unique microstructure, and seamless contact with NF.

Summary: Metal-organic frameworks (MOFs) have been widely used as nanozymes in biosensing. However, they suffer from the issues of easy agglomeration and low conductivity. To address these problems, researchers have developed a ligand exchange method with polydopamine (PDA) to synthesize MOF PDA-MIL-88B, which exhibits enhanced peroxidase-like activity and can be used for glucose detection.

Summary: In this study, a non-enzymatic hydrogen peroxide sensor was developed using a waterborne carbon nanotube ink containing catalytic submicrometric particles of magnetite. The resulting Fe3O4/CNT ink coated electrodes exhibited high-performance values towards the detection of H2O2, with a sensitivity of 1040 mu A cm(-2) mM(-1) and high stability, losing only 20% of their catalytic performance after three weeks.

Summary: In this study, a simple and reliable surface-enhanced Raman spectroscopy (SERS) method was developed for sensitive and selective detection of aflatoxin B1 (AFB1) in peanut samples. The method used dummy molecularly imprinted polymers (DMIPs) to selectively enrich AFB1 from the samples, and a thioctic acid-decorated AgNPs monolayer film (TA-AgNPs MF) as a SERS-active substrate to determine the amount of AFB1. The SERS assay showed high detection sensitivity for AFB1 in peanut samples with a limit of detection of 0.1 μg L-1 and a linear concentration range from 0.1 to 10 μg L-1.
