The characterisation and design improvement of a paper-based E.coli impedimetric sensor

Author: Bezuidenhout, Petrone H ; Kumar, Raju ; Wiederoder, M ; Schoeman, J ; Land, Kevin J ; Joubert, T-H Date: Feb 2017 This paper describes the development and optimisation of a paper-based E. coli impedimetric biosensor for water quality monitoring. Impedimetric biosensing is advantageous because it is a highly sensitive, label-free, real-time method for the ... Read more
Detection of biological analytes using surface plasmon resonance as a biosensing technique for possible development of a point of care diagnostic tool

Author: Malabi, Rudzani ; Manoto, Sello L ; Ombinda-Lemboumba, Saturnin ; Maaza, Malik ; Mthunzi-Kufa, Patience Date: Feb 2019 Surface Plasmon Resonance (SPR) is a very powerful optical sensing technique that detects bimolecular binding interactions and it has turned out to be a suitable platform for clinical analysis. In biological and chemical sensing applications, ... Read more
Development of collinear transmission plasmonic biosensor for detection of HIV-1

Author: Ombinda-Lemboumba, Saturnin ; Manoto, Sello L ; Maphanga, Charles P ; Malabi, Rudzani ; Mthunzi-Kufa, Patience Date: Feb 2020 Surface Plasmon Resonance (SPR) which is widely used to study interactions between different types of biomolecules, has emerged as a technique of choice for rapid and quantitative analyses. However, there are still some challenges on the use ... Read more
Label-free detection of mutations in the HIV genome using a surface plasmon resonance biosensor

Author: Lugongolo, Masixole Y ; Manoto, Sello L ; Maphanga, Charles P ; Ombinda-Lemboumba, Saturnin ; Thobakgale, Setumo L ; Mthunzi-Kufa, Patience Date: Mar 2021 Surface plasmon resonance (SPR) biosensors are optical materials that measure changes in the refractive index as they monitor non-covalent molecular interactions in real time. These utilise a label free analytical approach, which does not ... Read more
Towards HIV detection: Novel Poly(propylene imine) Dendrimer-Streptavidin platform for electrochemical DNA and gp120 aptamer biosensors

Author: John, SV ; Rotherham, LS ; Khati, M ; Mamba, BB ; Arotiba, OA Date: Jul 2014 The detection of sequence – specific DNA and HIV glycoprotein 120 (gp120) based on novel generation 4 poly(propylene imine) dendrimer/streptavidin platform is reported. The platform was prepared by the electrodeposition of the dendrimer on a ... Read more
