Advances in Biosensors for Point-of-care Testing and Diagnostics

Biosensors have huge potential for point-of-care testing and diagnostics as they detect biomolecules effectively and precisely and can be employed in low-resource settings. Some recent developments in biosensors for point-of-care testing and diagnosis include:

Paper-based biosensors: Paper-based biosensors are inexpensive, portable, and disposable devices that can be used for point-of-care testing. They detect biomolecules such as glucose, cholesterol, and pathogenic pathogens using paper as a substrate.

Smartphone-based biosensors: Smartphone biosensors: Smartphone biosensors are small and portable devices that can be used for point-of-care testing. They detect and examine biomolecules such as proteins and nucleic acids using a smartphone's camera and computational power.

Wearable biosensors: Wearable biosensors, such as patches and wristbands, can be used continuously to track biomarkers such as glucose and lactate in real time. They provide patients with chronic illnesses with non-invasive easy monitoring.

Microfluidic biosensors: Microfluidic biosensors are miniature devices designed for analyzing small amounts of biological fluids with high sensitivity and specificity. They can be used to perform point-of-care testing on a wide range of biomolecules, including proteins and nucleic acids.

Nanoparticle-based biosensors: Nanoparticle-based biosensors: Nanoparticles, such as gold nanoparticles and quantum dots, have been utilized for developing biosensors that can detecting and quantifying a wide range of biomolecules, including infectious agents and cancer biomarkers.

Multiplexed biosensors: Multiplexed biosensors are devices that can detect and determine various biomolecules in a single test. They give quick and accurate point-of-care diagnostics for several kinds of diseases and conditions.

Overall, biosensors provide new and innovative methods for point-of-care testing and diagnosis, particularly in low-resource settings. In this field, ongoing research is focused on developing unique technologies and applications that may improve the accuracy, sensitivity, and specificity of biosensors for point-of-care testing and diagnostics.
