We present a straightforward and generic strategy for coating upconverting nanoparticles (UCPs) with polymer shells for their protection, functionalization, conjugation, and for biocompatibility. UCPs are attracting much attention for their potential use as fluorescent labels in biological applications. However, they are hydrophobic and non-compatible with(More)
A solid-phase synthesis approach to prepare molecularly imprinted polymer nanoparticles (MIP-NPs) specific for trypsin is described. The protein is immobilized on a solid support upon which thermoresponsive MIP-NPs are synthesized. The MIP-NPs are released by a simple temperature change, resulting in synthetic antibody mimics exhibiting high specificity and(More)
Advanced tools for cell imaging are of great interest for the detection, localization, and quantification of molecular biomarkers of cancer or infection. We describe a novel photopolymerization method to coat quantum dots (QDs) with polymer shells, in particular, molecularly imprinted polymers (MIPs), by using the visible light emitted from QDs excited by(More)
A novel approach using one-pot synthesis for the production of uniform, iniferter-bound polystyrene core nanoparticles of size 30-40 nm is described. Conventional oil-in-water emulsion polymerisation of styrene and divinylbenzene, combining a hybrid initiation system (thermal and UV), triggered sequentially, was employed to form the surface-bound(More)
Chelation-assisted click chemistry at micromolar copper concentrations : A simple procedure enabling functionalization of unprotected reducing oligosaccharides and rapid glycoconjugation at low copper concentrations is reported. It can be used to functionalize biomolecules bearing alkyne moieties introduced through metabolic labeling, including in live(More)
The ability to program and mimic the dynamic microenvironment of living organisms is a crucial step towards the engineering of advanced bioelectronics. Here, we report for the first time a design for programmable bioelectronics, with 'built-in' switchable and tunable bio-catalytic performance that responds simultaneously to appropriate stimuli. The designed(More)
Molecularly imprinted polymers (MIPs) are synthetic antibody mimics capable of specific molecular recognition. Advantageously, they are more stable, easy to tailor for a given application and less expensive than antibodies. These plastic antibodies are raising increasing interest and one relatively unexplored domain in which they could outplay these(More)
