Main Laboratories and Facilities Equipment

(6C-033a, Ramachandra R. Dasari)

The Transdermal Glucose Detection Laboratory has two near-infrared (NIR) Raman systems. Both of the systems contain deep depletion CCDs and solid state diode lasers at 830 nm. One is used as a laboratory system for studies related to blood analyte concentrations; the other is a portable system transported to hospitals for clinical investigations.
