“Reviews Showcase” in Chemistry - A European Journal
Our recent concept article on Directing Traffic: Halogen-Bond-Mediated Membrane Transport has been selected by the Editorial Office for the Showcase of outstanding Review-type articles in Chemistry - A European Journal. In this article, we describe a novel strategy involving halogen bonding for increasing the cellular uptake of small molecules and proteins.
“Hot Paper” in Chemistry - A European Journal
Our new paper on modelling the inhibition of selenoproteins by small molecules using cysteine and selenocysteine derivatives has been selected as a "Hot Paper" in Chemistry - A European Journal. We demonstrate, for the first time, that the arylselenium species eliminated from the selenocysteine derivatives exhibit significant redox activity, which may have a significant effect on the cellular redox state during the inhibition of selenoproteins.
“Hot Paper” in Angewandte Chemie
Our new paper on membrane transport of green fluorescent protein in mammalian cells has been selected as a "Hot Paper" in Angewandte Chemie. We show that the introduction of an iodine atom to one of the tyrosine residues facilitates the cellular entry of green fluorescent proteins, providing a strategy for the delivery of macromolecules into mammalian cells.
In a first, IISc team directly delivers protein into cells - The Hindu
In a breakthrough that might have huge medical implications, researchers at Bengaluru’s Indian Institute of Science (IISc) have used a novel strategy to directly deliver proteins into mammalian cells. Proteins are big molecules and so cannot enter the cells on their own. So a team from IISc substituted a hydrogen atom of the protein with an iodine atom to achieve a nearly sixfold increase in protein uptake by cells.
ChemistryViews: Halogen-Mediated Transport through Cell Membranes
Our work on Halogen-Mediated Membrane Transport, published in Chemistry - A European Journal has been featured on ChemistryViews, Wiley-VCH's chemistry portal. We found that the introduction of iodine atoms into a series of fluorescent molecules (example pictured) remarkably enhances the cellular uptake. Using two iodine atoms, the cellular uptake can be increased to more than 95 % in mammalian cells.

Making cellular probes more effective - BusinessLine
Scientists at Indian Institute of Science, Bengaluru have found a way to enhance uptake of fluorescent probes into cells. They have found that by replacing hydrogen atoms at crucial places of napthalimide with iodine or bromide atoms makes it easier to break into cells.
Iodine Magic - A highlight of our recent work in The Hindu
Studying the uptake of thyroid hormone may become easier - Fluorescent probes are routinely used for studying drug delivery, membrane activity and cellular functions. By substituting two hydrogen atoms of a commonly used fluorescent probe (naphthalimide) with iodine, researchers at the Indian Institute of Science (IISc), Bengaluru, have been able to increase the cellular uptake of the probe molecule from 5-8% to 98%.
Sourav Ghosh has been awarded a Poster Prize at the CRSI-NSC-23
Sourav Ghosh has been awarded a poster prize for his work titled "Nanoisozymes: Crystal-Facet-Dependent Enzyme-Mimetic Activity of V2O5 Nanomaterials," at the 23rd CRSI National Symposium in Chemistry (NSC-23) at IISER Bhopal, during July 13 - 15, 2018.
Namrata Singh Wins a Poster Prize at Gordon Research Conference
Namrata Singh has been awarded a poster prize for her work on "An antioxidant nanozyme providing cytoprotection in Parkinson’s Disease Model," at the Gordon Research Conference “Metals in Medicine” organized in Proctor Academy, New Hampshire, USA, during June 24 - 29, 2018. The poster has also been selected for a Poster Slam.
IISc team synthesizes artificial enzyme
Nanozyme mimics the antioxidant enzyme glutathione peroxidase - Nanomaterials that can behave like human enzymes have now been successfully synthesized by a team of researchers from Indian Institute of Science (IISc), Bengaluru. They produced the new nanozyme — nanomaterial with enzyme-like activity — by using vanadium pentoxide nanocrystals of just 150-200 nm size.

Highlight of our work on Mn3O4 nanozyme in "The Hindu" Newspaper
A team of researchers from the Indian Institute of Science (IISc) Bengaluru has fabricated a metal oxide nanomaterial that is capable of mimicking all three major cellular antioxidant enzymes, thereby controlling the level of reactive oxygen species (ROS) inside cells. Based on in vitro test results, the nanomaterial appears a promising candidate for therapeutic applications against oxidative stress-induced neurological disorders, particularly Parkinson’s.
