“…The FETbased biosensors are chosen over these structures for the simplest feasible biomolecule detection [9,10] without the need for an explicit transducer. Technology advancements have resulted in smaller devices [21,22] and more leakage current [23][24], both of which require attention. Furthermore, thanks to their more affordable mass production, JLFETs as biosensors offer significant advancements in the field of fabrication.…”

“…The potential changes when positively or negatively charged biological molecules are added to the nanogap. Positive-charged biomolecules reduce the depletion barrier, while negative-charged ones raise it [22]. Because capacitance below the cavity zone depends on dielectric constants [31], the location of the energy band is governed by flat band voltage fluctuations near to the cavity zone.…”

A number of more recent discoveries in microbiology have made reliable identification of nano-biomolecules and extensive analyses of them necessary. A variety of proteins, including DNA, biotin-streptavidin, amino acids, as well as many types of bacteria and viruses, must be found and analyzed in order to fully comprehend any odd behavior occurring inside of live cells. Rapid testing and detection are essential steps in preventing undiscovered biohazards from eradicating the human race and other terrestrial living things. Since many decades ago, developing an accurate, affordable biosensor has been a struggle for scientists [1]. When compared to pricey laboratory-based sensors and detection methods, FET-based lab-on-chip nano biosensors appear to be a promising substitute. It is significantly more dependable than conventional bulk sensors because of its size, affordability, low power consumption, resilience, faster response time, and better sensitivity [1]. Due to their precision, adaptability, and compatibility with embedded systems, dielectrically modulated FET biosensors with Nano cavities are emerging as a promising research area that can yield useful data on bio-analyses. As an alternative to conventionally doped TFET devices, using a charge plasma SiGe-heterojunction double gate TFET, a label-free biosensor can be produced, bypassing the need for conventional semiconductors, which require a large thermal budget and are susceptible to random dopant fluctuations (RDFs). The effect of changing the dielectric constant (k), the positive and negative charge density, the gate work function, and the cavity size has been investigated to better understand how these factors affect the performance of the proposed biosensor. These parameters modify the biosensor's electric characteristics, improving detection [2]. There is also discussion of how these factors influence the device's drain current, electric field, surface potential, sub-threshold swing (SS), insulator-to-metal film (ION/IOFF) ratio, and electron tunneling rate (ETR). The sensitivity of the drain current in the proposed biosensor is also investigated. There is no restriction on whether or whether the proposed structure is used for charged or neutral molecules.Under lower supply voltages, it is discovered that the SG-DM current JLFET's sensitivity is high, measuring 1.2 *10^3, with a potential sensitivity of 1.4 V. A result, the SG-DM [2] JLFET exhibits good application potential while consuming little power and having ahigh sensitivity.

“…Heavy metal contamination in the environment has increased due to the expansion of urbanization and industrialization over the past few decades, posing a serious threat to ecosystems and public health. Sewage discharge stands out as a significant contributor to heavy metal pollution among the numerous sources because of the variety of toxins it contains [3][4][5]. Concerns related to the potential bioaccumulation of heavy metals in plants have been raised due to the close proximity of sewage treatment facilities to agricultural lands and water bodies.…”

The proper disposal of manufacturing and consumer waste, including sewage sludge, is one of the numerous environmental issues facing today's society. In addition to posing serious health concerns to humans, anthropogenic activities are a major source of environmental pollution and can result in an overabundance of pollutants entering the terrestrial ecosystem. The goal of the current study was to determine how existing tree and plant species near sewage drains were affected by the bioaccumulation of carcinogenic metals (Cd, Ni, Co, and Cr) together with other heavy metals. These heavy metals found in the sewage are hazardous to the health of both people and the environment. To further understand how well these plant species adapted to the metal-contaminated soil, many biological parameters, including stomatal density, leaf length, leaf area index, and stress hormone levels, were investigated. For every species included in the study, soil samples were taken near the sewer drains and the rhizosphere. The plant species' leaves and roots (where feasible) were also harvested. To check for metal buildup in the wood, various tree species had their trunks harvested. All of these samples go through an acid digestion process using an aquaregia combination. Following digestion, the samples are examined using Microwave Plasma Atomic Emission Spectroscopy (MP-AES) for the presence of heavy metals. In this study, we briefly address the findings on the accumulation of heavy metals by certain plant species.
