In the current research, unique Nano-Embedded Fungus (NEF), made by the synergic association of silver nanoparticles (AgNPs) and endophytic fungus (Piriformospora indica), is studied, and the impact of NEF on black rice secondary metabolites is reported. AgNPs were synthesized by chemical reduction process using the temperature-dependent method and characterized for morphological and structural features through UV visible absorption spectroscopy, zeta potential, XRD, SEM-EDX, and FTIR spectroscopy. The NEF, prepared by optimizing the AgNPs concentration (300 ppm) in agar and broth media, showed better fungal biomass, colony diameter, spore count, and spore size than the control P. indica. Treatment with AgNPs, P. indica, and NEF resulted in growth enhancement in black rice. NEF and AgNPs stimulated the production of secondary metabolites in its leaves. The concentrations of chlorophyll, carotenoids, flavonoids, and terpenoids were increased in plants inoculated with P. indica and AgNPs. The findings of the study highlight the synergistic effect of AgNPs and the fungal symbionts in augmenting the secondary metabolites in leaves of black rice.

The current study is the first to describe the construction of an electrochemical sensor based on a molecularly imprinted polymer (MIP) for specific and sensitive detection of trimethylamine (TMA) in human body fluid such as urine. The MIP designed was based on polydopamine (PDA), which was made with and without TMA using a polymerization technique. On the glass coated with indium tin oxide, the MIP, NIP, and non-sonicated polymer (PPy-TMA) were all individually deposited. Fourier transform infrared spectroscopy, scanning electron microscopy, and electrochemical techniques were used to study the chemical, morphological, and electrochemical characteristics of MIP, non-imprinted polymer, and PDA-TMA. Differential pulse voltammetry was used to record the detection response, which demonstrated that as TMA concentration increased, the peak current increased as well. With a sensitivity of 2.47 A mL ppm-1 cm-2, the MIP sensor demonstrated a dynamic detection range of 1–15 ppm. The new sensor is simple to build and use and it can detect TMA in human fluids like urine with great precision. The current study lays the groundwork for developing MIP-based sensors to detect additional compounds that play role in human health and are originating from gut microbiota.

“…Additionally, the biosensor was successfully applied for the detection of organophosphorus compounds in milk and drinking water samples. Lakshmi et al utilized chitosan to functionalize Au@CeO 2 synthesized by wet chemical synthesis, forming a film on an indium tin oxide electrode and fixing nucleic acid aptamers to detect chlorpyrifos with a lower limit of 0.12 pM [ 41 ]. Wan et al designed an electrochemical detection platform based on sandwich core-shell nanocomposites [ 42 ].…”

The excessive use of pesticides and drugs, coupled with environmental pollution, has resulted in the persistence of contaminants on food. These pollutants tend to accumulate in humans through the food chain, posing a significant threat to human health. Therefore, it is crucial to develop rapid, low-cost, portable, and on-site biosensors for detecting food contaminants. Among various biosensors, polymer-based biosensors have emerged as promising probes for detection of food contaminants in recent years, due to their various functions such as target binding, enrichment, and simple signal reading. This paper aims to discuss the characteristics of five types of food pollutants—heavy metals, pesticide residues, pathogenic bacteria, allergens, and antibiotics—and their adverse effects on human health. Additionally, this paper focuses on the principle of polymer-based biosensors and their latest applications in detecting these five types of food contaminants in actual food samples. Furthermore, this review briefly examines the future prospects and challenges of biosensors for food safety detection. The insights provided in this review will facilitate the development of biosensors for food safety detection.
