Diagnostic Devices: Microneedle‐Based Transdermal Sensor for On‐Chip Potentiometric Determination of K+ (Adv. Healthcare Mater. 6/2014). Issue 6 (June 2014) - Miller, Philip R.
Abstract A transdermal sensing platform for detection of electrolytes is developed by P. R. Miller, R. Narayan, R. Polsky and colleagues. On page 876, hollow polymer microneedles are integrated with a microfluidic chip for detecting potassium using a solid state ion selective electrode transducer. The device could one day be used as an on body point‐of‐care medical diagnostic device.
