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
A comparison of different silver inks for printing of conductive tracks on paper substrates for rapid prototyping of electronic circuits

Author: Bezuidenhout, PH ; Smith, S ; Mbanjwa, M ; Land, KJ ; Joubert, T-H Date: Nov 2015 This study compares the performance between two commercially-available electrically conductive silver inks, Harima NPS-J nanopaste and the NBSIJ-FD02 Mitsubishi conductive ink, used in rapid prototyping of electronic circuits. The comparative ... Read more
Comparison of inkjet-printed silver conductors on different microsystem substrates

Author: Kruger, Jene ; Bezuidenhout, Petrone H ; Joubert, T-H Date: Sep 2016 Applications for diagnostic and environmental point-of-need require processes and building blocks to add smart features to disposable biosensors on low-cost substrates. A novel method for producing such biosensors is printing electronics using ... Read more
The design and manufacturing of a paper-based e.coli biosensor

Author: Bezuidenhout, PH ; Schoeman, J ; Joubert, T-H Date: Jan 2016 Printed electronics employ additive manufacturing processes and has several application possibilities for bespoke or large area devices on flexible or inexpensive substrates. One of the most compelling applications of this technological advance ... Read more
Inkjet-printed conductive features for rapid integration of electronic circuits in centrifugal microfluidics

Author: Kruger, J ; Smith, S ; Land, K ; du Plessis, M ; Joubert, T-H Date: May 2015 This work investigates the properties of conductive circuits inkjet-printed onto the polycarbonate discs used in CD-based centrifugal microfluidics, contributing towards rapidly prototyped electronic systems in smart ubiquitous biosensors, ...

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
Integrating integrated circuit chips on paper substrates using inkjet printed electronics

Author: Bezuidenhout, Petrone H ; Land, Kevin J ; Joubert, T-H Date: Nov 2016 This paper investigates the integration of silicon and paper substrates using rapid prototyping inkjet printed electronics. Various Dimatix DMP-2831 material printer settings and adhesives are investigated. The aim is to robustly and effectively ... Read more
A low-cost potentiostat for point-of-need diagnostics

Author: Bezuidenhout, Petrone H ; Smith, Suzanne ; Land, Kevin J ; Joubert, T-H Date: Sep 2017 The work presented details the development of a lowcost potentiostat, with the aim of creating an ink-jet printed hybrid paper-based low-cost sensing system for rapid water quality monitoring. Potentiostats exhibit high sensitivities and can ... Read more
A low-power CMOS operational amplifier IC for a heterogeneous paper-based potentiostat

Author: Bezuidenhout, Petrone H ; Land, Kevin J ; Joubert, T-H Date: Sep 2016 Electrochemical biosensing is used to detect specific analytes in fluids, such as bacterial and chemical contaminants. A common implementation of an electrochemical readout is a potentiostat, which usually includes potentiometric, amperometric, ... Read more
Micro-incubator for bacterial biosensing applications

Author: Clasen, E ; Land, Kevin J ; Joubert, T-H Date: Sep 2016 The presence of Escherichia coli (E. coli) is a commonly used indicator micro-organism to determine whether water is safe for human consumption. This paper discusses the design of a micro-incubator that can be applied to concentrate bacteria ... 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
