Preclinical Outsourcing to India

The outsourcing segment is witnessing rapid changes with respect to the nature of work outsourced and the location. Cost is the major driver but other considerations such as infrastructure and government policies can also be important drivers for decision making. The last couple of years have been a trying time for all CROs. The global economic meltdown has hit research budgets especially hard. The new challenges facing Contract Research Organizations call for a radically revised approach and a new model that would push the boundaries of this business further and would blur the line between client and vendor further. I believe the term Contract Research Organization (CRO), is a misnomer to begin with (often confused with Clinical Research Organization), has now morphed into a new type of company viz Contract Innovation Services (CIS). Clients are no longer just happy to outsource odds and ends of the development piece but are looking to their vendors for a massive amount of innovation input. This input is increasingly across both the chemistry and discovery domains. This new paradigm calls for CIS companies to develop new platforms, create intellectual propertythat is of service to clients andinnovate processes to meet new found customer expectations.

Plenary Talk: Biosensor and Single Cell Manipulation using Nanopipettes @ Amriteshwari Hall

Biosensor and Single Cell Manipulation using Nanopipettes

Approaching sub-cellular biological problems from an engineering perspective begs for the incorporation of electronic readouts. With their high sensitivity and low invasiveness, nanotechnology-based tools hold great promise for biochemical sensing and single-cell manipulation. During my talk I will discuss the incorporation of electrical measurements into nanopipette technology and present results showing the rapid and reversible response of these subcellular sensors  to different analytes such as antigens, ions and carbohydrates. In addition, I will present the development of a single-cell manipulation platform that uses a nanopipette in a scanning ion-conductive microscopy technique. We use this newly developed technology to position the nanopipette with nanoscale precision, and to inject and/or aspirate a minute amount of material to and from individual cells or organelle without comprising cell viability. Furthermore, if time permits, I will show our strategy for a new, single-cell DNA/ RNA sequencing technology that will potentially use nanopipette technology to analyze the minute amount of aspirated cellular material.

Invited Talk: Nanomaterials for ‘enzyme-free’ biosensing @ Amriteshwari Hall

Nanomaterials for ‘enzyme-free’ biosensing

Enzyme based sensors have many draw backs such as poor storage stability, easily affected by the change in pH and temperature and involves complicated enzyme immobilization procedures.  To address this limitation, an alternative approach without the use of enzyme, “non-enzymatic” has been tried recently. Choosing the right catalyst for direct electrochemical oxidation / reduction of a target molecule is the key step in the fabrication of non-enzymatic sensors.

Non-enzymatic sensors for glucose, creatinine, vitamins and cholesterol are fabricated using different nanomaterials, such as nanotubes, nanowires and nanoparticles of copper oxide, titanium dioxide, tantalum oxide, platinum, gold and graphenes. These sensors selectively catalyse the targeted analyte with very high sensitivity. These nanomaterials based sensors combat the drawbacks of enzymatic sensors.

Novel Cell-Based Biosensors for High Throughput Toxin Detection and Drug Screening Applications

Over the last decade there has been focus on the development of cellbased biosensors to detect environmental toxins or to combat the threats of biological warfare. These sensors have been shown to have multiple applications including understanding function and behaviour at the cellular and tissue levels, in cell electrophysiology and as drug screening tools that can eliminate animal testing. These factors make the development of cell-based biosensors into high throughput systems a priority in pharmacological, environmental and defence industries (Pancrazio J J et al. 1999, Kang G et al. 2009, Krinke D et al. 2009). We have developed a high through-put in vitro cell-silicon hybrid platform that could be used to analyze both cell function and response to various toxins and drugs. Our hypothesis was that by utilizing surface modification to provide external guidance cues as well as optimal growth conditions for different cell types (Cardiac and Neuronal), we could enhance the information output and content of such a system. An intrinsic part of this study was to create ordered or patterned functional networks of cells on Micro-electrode arrays (MEA). Such engineered networks had a two-fold purpose in that they not only aided in a more accurate analysis of cell response and cell and tissue behaviour, but also increased the efficiency of the system by increasing the connectivity and placement of the cells over the recording electrodes. Here we show the response of this system to various toxins and drugs and the measurement of several vital cardiac parameters like conduction velocity and refractory period (Natarajan A et al. 2011)
