German Researchers Create Non-invasive Lab-on-a-Chip Biosensor That Detects Antibiotic Levels from Breath Samples

Should the device prove effective, it could replace invasive point-of-care blood draws for clinical laboratory testing during patient drug therapy monitoring What if it were possible to perform therapeutic drug monitoring (TDM) without invasive blood draws using breath alone? Patients fighting infections in hospitals certainly would benefit. Traditional TDM can be a painful process for patients, one that also brings risk of bloodline infections. Nevertheless, regular blood draws have been the...

Researchers Develop ‘Smart’ Microneedle Adhesive Bandage System for Monitoring Sodium, Glucose, pH, and More

Platform could be next breakthrough in quest for painless technology to replace in-patient phlebotomy blood draws for many clinical laboratory tests In a proof-of-concept study, scientists from Israel and China have developed a “smart” microneedle adhesive bandage that measures and monitors in real time three critical biomarkers that currently require invasive blood draws for medical laboratory tests commonly performed on patients in hospitals. The “smart” microneedle system developed by...

Tufts University School of Engineering Researchers Have Developed Tooth-mounted Sensors That Monitor Glucose, Salt, and Alcohol in Foods as They Enter the Body

Tuft’s proof-of-concept demonstration study shows how changes in saliva can be employed as biomarkers for development of future diagnostic monitoring devices and applications For years, pathologists and dentists have recognized that the mouth contains many useful biomarkers for a wide range of health conditions and diseases. Now a study by a research team at Tufts University School of Engineering (Tufts) has demonstrated that a tooth-mounted sensor can reliably measure certain target markers....
