The nanogels were covalently interlinked via free-radical coupling at 37 ☌ to form transparent, ductile, hydrogels. The concentrated (functionalised) nanogel dispersions retained their pH-responsiveness, were shear-thinning and formed physical gels at pH 7.4. To demonstrate their functionalisation potential, glycidyl methacrylate was reacted with the –COOH chemical handles and the nanogels were converted to macro-crosslinkers.
Inspired by the ability of polar surfaces to enhance nanoparticle stabilisation, we report the first examples of pH-responsive polyacid nanogels containing high –COOH contents prepared by a simple, scalable, aqueous method. Synthesising polyacid nanogels that show triggered swelling using a scalable approach is a key objective of polymer colloid chemistry. Khan K, Ktindig EP (1996) Org Chem 61:2258 Miiller P, Nury P. They are of major interest for advanced surface coatings, drug delivery, diagnostics and biomaterials. Thayumanavan S (2002) Angew Chem Int Ed 41:716 Mukaiyama T, Soai K, Sato T.
Excellent novel by Balakumaran.Must read book.

Its contestants are couples who are generally TV stars in their own right, often from the television industry. 'Thai' Thayumanavan, professor of chemistry at the University of Massachusetts Amherst is awarded the Mahoney Life Sciences Prize for his. Purpose of life cant be explained in much simpler way than above.

Jodi Number One is an annual series reality dance show on the Vijaytv channel. Nanogels are crosslinked polymer particles with a swollen size between 1 and 100 nm. Vijay TV is back again with Jodi No 1 Season 7.
