Author:Du Plessis, A; Strydom, C; Botha, LDate:Mar 2010Changes in the laser induced molecular dissociation of 1,1,1-trichloroethane (TCE) were studied using a range of intensities and standard laser wavelengths with nanosecond and femtosecond pulse durations. TCE contains C-H, C-C and C-Cl bonds ...Read more
Author:Mthunzi-Kufa, Patience; Dholakia, K; Gunn-Moore, FDate:Aug 2011Owing to their self renewal and pluripotency properties, stem cells can efficiently advance current therapies in tissue regeneration and/or engineering. Under appropriate culture conditions in vitro, pluripotent stem cells can be primed to ...Read more
Author:Du Plessis, A; Botha, GN; Botha, LRDate:Jul 2011Results from experiments aimed at bimolecular chemical reaction control of CO and H2 at room temperature and pressure, without any catalyst, using shaped femtosecond laser pulses are presented. A stable reaction product (CO2) was measured ...Read more
Author:Mthunzi-Kufa, PatienceDate:Feb 2010Recently, laser light sources of different regimes have emerged as an essential tool in the biophotonics research area. Classic applications include, for example: manipulating single cells and their subcellular organelles, sorting cells in ...Read more
Author:Mthunzi-Kufa, Patience; Gunn-Moore, FJ; Dholakia, KDate:Jun 2009Various methods including chemical, viral or physical approaches have been developed to trigger transient membrane permeabilisation with limited cytotocixity in cells. Such developments permit efficient cytoplasmic delivery of genes, ...Read more
Author:Molukanele, P; Du Plessis, A; Roberts, T; Botha, L; Khati, M; Campos, WDate:Sep 2010Potential for the selective deactivation of viruses while leaving the sensitive material such as the host cell unharmed was studied using a femtosecond laser system, and preliminary results are reported.Read more
