Systematic screening of different polyglycerin‐based dienophile macromonomers for efficient nanogel formation through IEDDA inverse nanoprecipitation [PDF]

open access: yes, 2019
Alternatives for strain‐promoted azide–alkyne cycloaddition (SPAAC) chemistries are needed because of the employment of expensive and not easily scalable precursors such as bicyclo[6.1.0]non‐4‐yne (BCN).

Orthogonal, metal-free surface modification by strain-promoted azide–alkyne and nitrile oxide–alkene/alkyne cycloadditions [PDF]

open access: yes, 2012
In this article we present a fast and efficient methodology for biochemical surface patterning under extremely mild conditions. Micropatterned azide/benzaldoxime-surfaces were prepared by microcontact printing of a heterobifunctional cyclooctyne oxime ...

A Decade of Bioorthogonal Chemistry [PDF]

open access: yesAccounts of Chemical Research, 2011
Inventing new chemical reactions is a long-standing passion of chemists, as reflected in the ever-popular field of reaction methodology. Historically, the environment in which newly crafted transformations would be performed imposed minimal limitations on reaction design; after all, solvents can be screened to find an optimal choice, temperature can be

Spreading of a mycobacterial cell-surface lipid into host epithelial membranes promotes infectivity

open access: yeseLife, 2020
Several virulence lipids populate the outer cell wall of pathogenic mycobacteria. Phthiocerol dimycocerosate (PDIM), one of the most abundant outer membrane lipids, plays important roles in both defending against host antimicrobial programs and in ...
