Gamma Radiation Induced Contraction of Alkyne Modified Polymer Hydrogels [PDF]

open access: yes, 2021
We describe the gamma radiation induced crosslinking of alkyne-modified dextran polymer gels. Crosslinking of the alkyne moieties leads to gel contraction and fusion with other gel objects, and can be used for controlled ...

New catalytic strategies for DNA and RNA alkylation using rhodium (II) and copper (I) carbenes - a versatile tool for applications in chemical biology [PDF]

open access: yes, 2015
A variety of nucleic acid substrates were catalytically alkylated with rhodium(II) and copper(I)-carbenoids generated from diazocarbonyl compounds. The alkylation took place via an N-H insertion reaction selectively targeting the nucleobases in single ...
