Among various biofluids, sweat stands out as a remarkable medium because of its easy accessibility and diverse biomarker profile, allowing for the possibility of ongoing health evaluations outside of traditional clinical environments. Recent advancements in material science, flexible electronics, and biosensor technologies have significantly advanced sweat-based wearable biosensors, enabling the smooth incorporation of sensors into patches, tattoos, clothing, and accessories. These devices, designed to detect ions, metabolites, hormones, and various biomolecules, show great potential for monitoring metabolic, physiological, and environmental indicators associated with health and wellness. Traditional methods for sweat sampling depended significantly on laboratory tools and had restricted biosensing abilities; nonetheless, innovative microfluidic systems now allow for immediate, on-skin collection and analysis of sweat in real time. This review explores the progress in sensor technologies-including colorimetric, potentiometric, and amperometric methods-that enhance the sensitivity, selectivity, and durability of biosensors based on sweat analysis. Hybrid platforms that integrate electrochemical and optical sensors demonstrate significant potential in the analysis of multiple biomarkers, facilitating advancements in personalized health monitoring, chronic disease management, and performance tracking.

These pesticides can cause symptoms ranging from minor skin rashes and vomiting to serious ones like impairing sperm quality, neural development, and conception rates. One such class of pesticides is the pyrethroids. Synthetic pyrethroids like cypermethrin cause various health issues such as numbness, itching, burning sensation, and in severe cases, loss of bladder, muscle weakness, salivation, shortness of breath and seizures.
