A Bluetooth-enabled biosensor has been developed for rapid detection of breast cancer biomarkers HER2 and CA15-3 in saliva, achieving detection limits as low as one femtogram per milliliter, significantly outperforming conventional ELISA methods. This noninvasive technology facilitates immediate results, greatly beneficial for cancer screening, particularly in rural areas. The study led by Hsiao-Hsuan Wan from the University of Florida highlights the biosensor's high accuracy and sensitivity, supporting its potential for broader clinical use pending further validation.
