[edit] Problem being addressed
There is a need to develop CD4 counters that do not rely on laboratory workers and expensive/complicated equipment. A counter that can be used by rural clinicians in the field without extensive training would greatly assist in managing HIV in rural areas.
[edit] Detailed description of the solution
Microfluidic cell chromatography isolates cells and other particles in a miniature sensing chamber, without the complex manual steps of blood tests. The system takes advantage of electrochemical sensing, using lysate impedance spectroscopy. The system uses a simple sensor that counts the captured CD4 cells by measuring their internal contents electrically. A hand-held instrument interprets the electrical signal, and reports the CD4 count within minutes.
