Applications: There are several applications of infection resistant material in healthcare setting such as for making a urinary catheter. Urinary catheters are under constant drainage of urinary fluid and are a common source of nosocomial infections and other complications due to formation of biofilm. To inhibit such biofilms, it is important to protect and cover both inner and outer surfaces and antimicrobials used for this purpose should have no known history of significant toxicity. However, even antibiotics generally fail to act against such biofilms. Currently rubber, silicone, polyurethane and teflon catheters are available with specific properties. However, these do not provide effective protection against the infection as any modification in the material does not show effectiveness towards infection after long time of catherization. The present invention provides a highly flexible material with long durable antimicrobial nature and a process of preparing such a material. A method has been developed to functionalize a Polyurethane material by immobilizing different nature of bioactive agents i.e chlorhexidine digluconate (Clx), functional nanosilver and nano zinc oxide. The bioactive agents are released sustainably in different media through the polyurethane material and thus the antimicrobial property is for a longer duration. The resultant nano-functional material exhibits high flexibility, less friction and long durability with antimicrobial nature. Applications: 1. Medical device such as catheter 2. Antimicrobial surfaces
Advantages: 1. It is flexible. 2. It is bacteriostatic or bactericidal in nature. 3. It shows resistance to both gram positive and negative bacteria. 4. It shows complete reduction in bacterial growth. 5. It has good mechanical strength and decrease in stiffness, thus making it amendable. 6. The drug effectiveness is for 7-30 days depending upon the functionalization and agent, while in prior art effectiveness has been shown for 4 days.

I-Mitra(आई-मित्र) Welcomes You..
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
