The first red‐shifted photoswitchable glycoconjugates are reported. Microwave‐assisted late‐stage C–H chlorination was employed to achieve tetra‐ortho‐chlorinated azobenzene glycoconjugates. To investigate orientational control in carbohydrate recognition, a red‐shifted glycoazobenzene alkanethioacetate was also prepared. Scope and limitations of late‐stage C–H chlorination of sugar derivatives is
ending in thiol groups, which enable attachment of the glycoconjugates to the goldsurface, have been prepared. manno‐GNPs with different spacers and variable density of mannose (oligo)saccharides have been obtained and characterized. Surface plasmon resonance (SPR) experiments with selected manno‐GNPs have been performed to study their inhibition potency towards DC‐SIGN binding to gp120. The tested manno‐GNPs

Methods of binding and detecting a microorganism on a solid substrate. The microorganism is bound on a solid substrate covalently bound to a capture agent having a saccharide moiety. A lectin capable of binding to the microorganism and the saccharide moiety of the capture agent is added to the sample to bind the microorganism on the solid substrate. Further provided are biosensor devices, such as a quartz crystal microbalance (QCM) device or a surface plasmon resonance (SPR) device, that incorporate the solid substrate for the detection of microorganisms.

Emulsion inversion, from water‐in‐oil (w/o) to oil‐in‐water (o/w), was accomplished by employing tetrahydropyran‐containing ligands that undergo facile deprotection, converting the nanoparticles from hydrophobic to hydrophilic. These ligand‐tailored nanoparticles were used to prepare w/o emulsions that were disrupted, and inverted, to o/w systems simply by lowering the solution pH. The inversion process
