Research Overview: Professor Vadgama's research interests include the development of biocompatible biosensors for reliable metabolite monitoring in critically ill patients. Specific systems include sensors for glucose and lactate. He is also investigating the interaction of cells and proteins at materials surface and is presently studying the use of spider silk as a tissue engineering scaffold. Underpinning techniques and technologies include: polymeric membranes, electrochemistry, impedance spectroscopy, in vivo metabolite sensors, bioprocess monitioring contact angle measurement and piezoelectric sensing.

 

Expertise: Biosensors, interfaces, polymers, membranes

 

Keynote Speech Title: Materials adaptation and interfacing for operationally stable electrochemical biosensors

 

Abstract- Biosensor research in recent years has led to diversification of bio-transducer combinations, which together with miniaturisation, has paved the way for new engineering design strategies and applications. However, for practical biomedical measurement, especially in diagnostic medicine, there is a citical need to secure controlling interfaces that facilitate a chemistry transduction sequence that is neither affected by cellular and colloid/protein deposition at the surface or by diffusible molecules able to create an extraneous response or to passivate the internal transduction surface. The materials basis for such control comes mainly from the use of polymeric membranes. These are typically microporoous or homogeneous and are designed variously to improve tissue and blood compatibility or to serve as low molecular weight cutoff and ionomeric barriers able to help reject undesired small and/or charged molecules. Device instability and interference are a special challange in the case of continuously operating biosensors. Here, surface fouling is a cumulative problem, recalibration not easy and in the case of tissue in vivo sensors, operating where the true concentration local concentration is unknown. We have adapted electrochemical enzyme based biosensors for such in vivo use, as these have a ready facility for miniaturisation. We have focussed on biocompatible barrier membranes inclusive of polyurethane and modified polycarbonate and PVC to undertake short term monitoring of oxygen glucose and lactate. The laminate combinations can be considered an ‘intelligent’ sensing interface, and one that has helped stabilise outputs. Alternative, planar ion selective electrodes (ISEs) have been fabricated using PEDOT:PSS for sweat pH and Na+ during exercise. More recently a smart textile with an ISE functionality has been developed capable of conformal device construction. More generally, the mix of smart materials and biosensors constitutes a convergent field with the potential to improve the leverage existing biosensor chemistries.

Keywords- Biosensor, polymer membrane, in vivo monitoring, ion selective textile.

Keynote Speech Title: Free-standing nanostructures at atomic scale: from growth mechanisms to local properties at the nanoscale

 

Technology at the nanoscale has become one of the mainchallenges in science as new physical effects appear and can be modulated atwill. Materials for spintronics, electronics, optoelectronics, sensing, energyapplications and new generations of functionalized materials are takingadvantage of the low dimensionality, improving their properties and opening anew range of applications. As developments in materials science are pushing tothe size limits of physics and chemistry, there is a critical need for understandingthe origin of these unique physical properties (optical and electronic) andrelate them to the changes originated at the atomic scale, e.g.: linked tochanges in (electronic) structure of the material.In the present work, I willshow how combining advanced electron microscopy imaging with relatedspectroscopies in an aberration corrected STEM will allow us to probe theelemental composition and electronic structure simultaneously with the opticalproperties in unprecedented spatial detail.Thetalk will focus on several examples in advanced nanomaterials for optical,plasmonic and energy applications. In this way the latest results obtained bymy group on direct Visualizing and modeling materials at atomic scale will helpto understand their growth mechanisms (sometimes complex [1,2]) and alsocorrelate their physical properties (electronic and photonic) at sub-nanometerwith their atomic scale structure. The examples will cover a wide range of nanomaterials:quantum structures self-assembled in a nanowire: quantum wires (1D) [3] andquantum dots (0D) [4,5] and other complex nanowire-like morphologies forphotonic and energy applications (LEDs, lasers, quantum computing, singlephoton emitters, water splitting cells, batteries) [7,8,9,10], nanomembranesand 2D sheets [8,11].
