A SYSTEM FOR OBTAINING BIOMLECULAR MEASURES BASED ON PIEZOELECTRIC TECHNOLOGY

摘要

A system for detecting various biomolecular measures is provided. The system has a biosensor device comprising a piezoelectric material, at least one conductive layer formed over the piezoelectric material, and at least one surface modified polymer layer formed over the piezoelectric material, wherein the at least one surface modified polymer layer is characterized by surface roughness of about under 10nm peak to peak, a hydrophobicity with a contact angle of at least 94 or a combination thereof. The system also has a sampling cascade comprising a hydrophobic housing with a sample presenting area and at least one recess adjacent to the sample presenting area for accommodating the biosensor device therein, and a hydrophilic holder formed on the sample presenting area for holding the liquid sample therein.
