IIT Guwahati researchers have used the contrasting water wetting behaviour for anti-counterfeiting measures. Unlike the rest of the surface, micropatterns produced through molecular printing are highly hydrophilic in nature and so absorb water and become visible to naked eyes when dipped in water or when moist air is blown. In a new approach to anti-counterfeiting, … Continue reading IIT Guwahati use contrasting water wetting behaviour for anti-counterfeiting

IIT Guwahati uses water-repelling cotton for sustained drug release
IIT Guwahati researchers have used extremely water-repelling cotton for sustained drug release lasting as long as 110 days. In moderately water-repelling cotton, the drug is released over 50 days. Two drugs — aspirin and tetracycline — were tested for sustained drug release. The released drug was able to kill pathogenic bacteria. Sustained release of drugs … Continue reading IIT Guwahati uses water-repelling cotton for sustained drug release
IIT Guwahati’s bone graft aids extensive bone formation
IIT Guwahati’s scaffold made of silk-bone cement composite doped with silicon and zinc metal ions has been found to extensively regenerate new bone tissue and blood vessels in rabbits in three months. At the end of three months, silk fibre gets degraded, bone cement gets absorbed, while silicon and zinc get leached out. The team is now … Continue reading IIT Guwahati’s bone graft aids extensive bone formation
IIT Guwahati’s chitosan-based gel selectively removes oil or water
Researchers at IIT Guwahati have chemically modified the chitosan to make it selectively remove either oil or water phase from an oil-water mixture. In a first, they made it possible to switch liquid repellence of the material from extremely water-repelling to extremely oil-repelling and vice versa. A natural biopolymer, chitosan (a kind of polysaccharide obtained from … Continue reading IIT Guwahati’s chitosan-based gel selectively removes oil or water
Podcast: Removing oil from water using aloe vera
Uttam Manna of IIT Guwahati explains how his team synthesised an extremely oil-repelling (super oleophobic) membrane using an aloe vera gel-based coating modified with some molecules to remove oil from water. The membrane could be reused at least 25 times to separate light and heavy oil from water with the efficiency of separation remaining above … Continue reading Podcast: Removing oil from water using aloe vera
IIT Guwahati uses aloe vera to remove oil from water
IIT Guwahati researchers have synthesised an extremely oil-repelling (super oleophobic) membrane using an aloe vera gel-based coating modified with some molecules. This is the first time a naturally occurring material has been used for the said purpose. The membrane could be reused at least 25 times to separate light and heavy oil from water with … Continue reading IIT Guwahati uses aloe vera to remove oil from water
Podcast: Fabricating a scaffold for cartilage repair
Yogendra Pratap Singh from IIT Guwahati explains how the biphasic scaffold fabricated using silk is superior to the existing ones. Since the entire scaffold is made of silk, the junction between the half that is spongy and mimics the cartilage while the other half is less porous and mimics the bone is seamless. In rabbits, … Continue reading Podcast: Fabricating a scaffold for cartilage repair
IIT Guwahati fabricates superior scaffold for cartilage repair
Using silk, researchers from IIT Guwahati have fabricated a biphasic scaffold where one half is spongy and mimics the cartilage while the other half is less porous and mimics the bone. The junction between the two phases is seamless. In rabbits, the fibre-reinforced scaffold allowed more bone formation, while the cartilage was regenerated and completely … Continue reading IIT Guwahati fabricates superior scaffold for cartilage repair
Podcast: Developing bioactive wound dressing, skin graft
IIT Guwahati researchers have developed bioactive wound dressings and bio-artificial skin by using silkworm silk fibroin as matrix and coating it with recombinant spider silk proteins. The recombinant spider silk reduced bacterial population by nearly four-fold and showed good anti-biofilm properties and recruited cells to the site of wound. The skin graft was bilayered (demis and epidermis) … Continue reading Podcast: Developing bioactive wound dressing, skin graft
