Welcome to the Center for Point Detection and Nano-bio-sensing


The focus of IPN is to fully exploit a UT developed “ACEK capacitive sensing” technology and develop novel 'sample in–result out' diagnostics for on-site detection of small molecules, proteins, biomarkers and pathogens from practical samples.  This collaborative initiative aims to use nanobiosensing technology to design, test, and validate rapid tests at point of need (PON) and/or point of care (POC) to facilitate clinical disease diagnosis and monitoring of environmental, food or water safety.  Some of our objectives include to diagnose diseases during office visit quickly and inexpensively, to provide easy identification of infectious pathogens or toxins in the field, and to generate point-of-care triage devices that can speed delivery of lifesaving treatment. 

Major Characteristics of ACEK Capacitive Sensing Technology:
Ø Rapid, < 1 minute from sample to result.
Ø Simple, -- One step operation performed by a lay person at point of need or care.
Ø Portable, -- small and light weight, comparable to a smart phone.
Ø Cost-effective, < $1 material cost/per test, < $200 reader system.
