handheld biosensors

Handheld biosensors are portable devices designed to detect and measure specific biological substances, such as glucose, pathogens, or toxins, quickly and accurately. They work by sensing molecules in samples like blood, saliva, or water, often using specialized materials that change in response to the target substance. These sensors provide immediate results, making them useful for medical diagnostics, environmental monitoring, and food safety. Their compact size and ease of use enable on-the-spot testing without the need for complex laboratory equipment, helping users make informed decisions efficiently.
