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.

Spatially Distributed and Hierarchical Nanomaterials in Biotechnology
Although nano materials are well investigated in biotechnology in their zero-, one- and two-dimensional forms, three-dimensional nanomaterials are relatively less investigated for their biological applications. Three dimensional nano materials are much more complex with several structural and hierarchical variables controlling their mechanical, chemical and biological functionality. In this talk examples are given of some complex three dimensional systems including, scaffolds, aggregates, fabrics and membranes. Essentially three types of hierarchies are considered: one-dimensional hierarchy, two-dimensional hierarchy and three-dimensional hierarchy each giving rise to unique behaviors.

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.
