Piezoelectric Biosensors

Piezoelectric biosensors use the piezoelectric effect to detect changes in mass or viscoelasticity on the sensor surface, observed in materials like quartz or ceramics. Coated with a specific biorecognition element, such as an antibody or enzyme for a target analyte, the interaction results in surface modifications, generating a measurable electrical signal.

Piezoelectric biosensors advantages:

Encompassing heightened sensitivity, swift response times, label-free detection and cost-effective to manufacture.
They are applicable for detecting a diverse range of analytes, including proteins, nucleic acids, and small molecules. 

Piezoelectric biosensors applications:

In disease diagnosis, drug discovery, and monitoring therapeutic drug levels.  
They also prove valuable in food safety testing, detecting pathogens, and environmental monitoring for identifying pollutants. 

In summary, piezoelectric biosensors emerge as a promising and versatile technology poised to transform healthcare and various industries. Ongoing research endeavors in this domain are concentrated on enhancing the sensitivity and selectivity of piezoelectric biosensors, alongside the development of novel materials and biorecognition elements for incorporation into these sensors
