Determination of the optical properties of PNIPAAm gels used in biological applications

Author: Singh, A ; Karsten, AE ; Mputle, I ; Chetty, A ; Naidoo, Kersch Date: Jul 2009 Poly(N-isopropylacrylamide) that is PNIPAAm is a temperature sensitive smart material which displays a lower critical solution temperature (LCST) at 33-35oC. At the lower critical solution temperature, the gel changes from hydrophilic to ... Read more
Experimental verification and validation of a computer model for light–tissue interaction

Author: Karsten, AE ; Singh, A ; Braun, MW Date: Apr 2011 Laser light is frequently used in both diagnostics and treatment of patients. For any laser treatment to be effective it is important to deliver the correct dose at the treatment site. Human skin scatters and absorbs laser light in the visible ... Read more
Robustness and accuracy of the calibration model for the determination of the optical properties of chicken skin

Author: Singh, A ; Karsten, AE ; Dam, JS Date: Oct 2008 The optical properties namely the absorption and reduced scattering coefficients of chicken skin taken from the breast was measured using an Integrating Sphere setup at 632.8nm. The properties were extracted using the multiple regression ... Read more
