Improved non-covalent biofunctionalization of Multi-Walled Carbon Nanotubes using Carbohydrates Amphiphiles with a Butterfly-Like Polyaromatic tail
We have developed an efficient strategy for the non-covalent functionalization of multi-wall carbon nanotubes (MWCNTs) which allows a biomimetic presentation of carbohydrates on their surface by π-π stacking interactions. The strategy is based on the use of...
Versatility and multifunctionality of highly reflecting Bragg mirrors based on nanoparticle multilayers
The use of both supported and flexible self-standing nanoparticle-based one dimensional photonic crystal films as effective frequency selective filters in the UV-vis-NIR is herein evaluated. The requirements to achieve a flat spectral response at the desired frequency...
Nitration of tyrosine 74 prevents human cytochrome c to play a key role in apoptosis signaling by blocking caspase-9 activation
Tyrosine nitration is one of the most common post-transcriptional modifications of proteins, so affecting their structure and function. Human cytochrome c, with five tyrosine residues, is an excellent case study as it is a well-known protein playing a double...
Organocatalytic Asymmetric Cyanosilylation of Nitroalkenes
A new catalyst type for a new reaction. The unprecedented cyanosilylation of nitroalkenes can be efficiently catalyzed by a bifunctional quinine derivative bearing tetra-alkylammonium cyanide and thiourea moieties. The activation of the nitroalkene by H-bonding to the...
Inhibition of Target of Rapamycin signaling and stress activate autophagy in Chlamydomonas reinhardtii
Autophagy is a catabolic membrane-trafficking process whereby cells recycle cytosolic proteins and organelles under stress conditions or during development. This degradative process is mediated by autophagy-related (ATG) proteins which have been described in yeasts,...
