CD-based microfluidics for primary care in extreme point-of-care settings

Author: Smith, S ; Mager, D ; Perebikovsky, A ; Shamloo, E ; Kinahan, D ; Mishra, D ; Delgado, SMT ; Kido, H ; Saha, S ; Ducrée, J ; Madou, M ; Land, K ; Korvink, JG Date: Jan 2016 We review the utility of centrifugal microfluidic technologies applied to point-of-care diagnosis in extremely under-resourced environments. The various challenges faced in these settings are showcased, using areas in India and Africa as ... Read more
A centrifugal microfluidic platform for point-of-care diagnostic applications

Author: Hugo, S ; Land, K ; Madou, M ; Kido, H Date: Feb 2014 Microfluidic systems enable precise control over tiny volumes of fluid in a compact and low-cost form, thus providing the ideal platform on which to develop point-of-care diagnostic solutions. Centrifugal microfluidic systems, also referred ... Read more
Contact angle studies on PDMS surfaces fouled by bovine serum albumin

Author: Windvoel, VT ; Mbanjwa, MB ; Land, K Date: 2010 Polydimethylsiloxane (PDMS) has a hydrophobic surface, forming a contact angle of around 110º with deionised water. It is due to its hydrophobic nature that the elastomer is prone to bio-fouling, such as non-specific adsorption of biomaterials ... Read more
Effect of nanoclay on optical properties of PLA/clay composite films

Author: Cele, HM ; Ojijo, Vincent O ; Chen, H ; Kumar, S ; Land, K ; Joubert, T ; De Villiers, MFR ; Ray, SS Date: Jun 2014 This article reports the modification of optical properties of biodegradable/biocompatible polylactide (PLA) using organically modified montmorillonite (OMMT) for microcantilever applications. PLA/OMMT composite films with various OMMT loadings ... Read more
Inkjet-printed silver tracks on different paper substrates

Author: Joubert, T-H ; Bezuidenhout, PH ; Chen, H ; Smith, S ; Land, K Date: Aug 2015 Inkjet printing is a widely used patterning method in industrial and scientific applications, and has also drawn attention in the field of printed electronics in recent years [1]. In this work, conductive silver tracks were achieved by inkjet ... Read more
A lensless, automated microscope for disease diagnostics

Author: Hugo, S ; Naidoo, T ; Swart, H ; Potgieter, S ; Van Rooyen, P ; Land, K Date: Mar 2012 Optical microscopy is widely accepted as one of the gold standards in disease diagnosis. However, factors such as cost and the need for a trained eye limit the prevalence of such equipment, particularly in resource-limited areas such as rural ... Read more
Low cost fabrication and assembly process for re-usable 3D polydimethylsiloxane (PDMS) microfluidic networks

Author: Land, K ; Mbanjwa, MB ; Govindasamy, K ; Korvink, JG Date: Sep 2011 A method to easily manufacture and assemble a polydimethylsiloxane (PDMS) based microfluidic device is described. The method uses low cost materials and reusable laser cut polymethyl methacrylate (PMMA) parts. In addition, the thickness of ... Read more
Microfluidic devices for biological applications

Author: Potgieter, S ; Land, K ; Kotze, L ; Sparrow, R Date: 2010 Microfluidics is a multi-disciplinary field that deals with the behaviour, control and manipulation of fluids constrained to sub-millilitre volumes. It is proving to be a useful tool for biological studies, affording advantages such as reduced ... Read more
Paper-based smart microfluidics for education and low-cost diagnostics

Author: Smith, S ; Moodley, K ; Govender, Ureshnie ; Chen, H ; Fourie, L ; Ngwenya, S ; Kumar, S ; Mjwana, P ; Cele, H ; Mbanjwa, MB ; Potgieter, S ; Joubert, T-H ; Land, K Date: Nov 2015 Current centralised healthcare models pose many challenges, particularly for developing countries such as South Africa, where travel and time costs make it difficult for patients to seek healthcare, even when urgently needed. To address this ... Read more
