Overview

Our research group is driven to develop simple and low-cost technologies that contribute towards creating a healthier society. This requires highly collaborative research: we work closely with colleagues from Biochemistry, Chemistry, Immunology, Mechanical Engineering and Chemical Engineering. Our efforts are focused on two main areas:

Create easy-to-use and equipment free biosensors. We have developed paper-based and flexible plastic (food wrap) sensors that detect the presence of specific pathogenic bacteria in water, food and other complex biological matrices (including fecal matter). This work is done in collaboration with the Li, Brennan, Pelton and Didar

Create methods and techniques to thermally stabilize biological materials. We have developed a simple technique to provide long term (months) thermal stability to a wide range of reagents, including various enzymes, oxygen sensitive organic molecules, RNA, phage and, recently, vaccines. The ability to ship enzymes across the world without the need to maintain a cold-chain distribution can have a great influence on global health, since the cost of vaccination campaigns would be drastically reduced. This work is done in collaboration with the Doust, Miller and Ashkar

Thermal Stabilization of Viral Vaccines in Low-Cost Sugar Films
SCIENTIFIC REPORTS

Most currently available vaccines, particularly live vaccines, require the cold chain, as vaccine efficacy can be significantly hampered if they are not stored in a temperature range of 2–8 C at all times.

Ready‐to‐use thermally stable mastermix pills for molecular biology applications
BIOTECHNOLOGY PROGRESS

Rolling circle amplification (RCA), polymerase chain reaction (PCR), and loop‐mediated isothermal amplification (LAMP), are powerful tools that can be used for gene manipulation, pathogen detection, and infectious disease diagnostics.

Tools for water quality monitoring and mapping using paper-based sensors and cell phones
WATER RESEARCH

In this paper we describe a combination of paper-based sensors and a novel smart-phone application for on-site quantification of colorimetric readouts as an ultra-low cost solution to monitoring water quality.
