The lack of a high-yield, renewable and low-cost synthesis method limits the potential applications of boron nitride with impressive characterizations. In this study, a facile method is developed for the preparation of chemically functionalized boron nitride nanosheets (BNNSs) by considering the quantity and quality of chemical materials involved in the synthesis process. The proposed green met...

We report the successful functionalization of optically accessible nanostructures, suitable for single-molecule experiments at physiological substrate concentrations, with polyethylene glycol. Characterization of the coating in terms of roughness, protein repellence, and specific immobilization of DNA is described. We present an application of this technique in the detection of polymerase activ...

A method for conjugation of ligands to the surface of exosomes was developed using click chemistry. Copper-catalyzed azide alkyne cycloaddition (click chemistry) is ideal for biocojugation of small molecules and macromolecules to the surface of exosomes, due to fast reaction times, high specificity, and compatibility in aqueous buffers. Exosomes cross-linked with alkyne groups using carbodiimid...

A straightforward route is proposed for the multi-gram scale synthesis of heterobifunctional poly(ethylene glycol) (PEG) oligomers containing combination of triethyloxysilane extremity for surface modification of metal oxides and amino or azido active end groups for further functionalization. The suitability of these PEG derivatives to be conjugated to nanomaterials was shown by pegylation of u...

We report the selective functionalization of uniform and heterostructured nanowires with self-assembled monolayers (SAMs) of (3-mercaptopropyl)trimethoxysilane (MPTMS). The wires were grown electrochemically in anodic aluminum oxide (AAO) templates. Selective deposition and removal of SAMs during nanowire growth permits the decoration of specific regions of the surface along the length of the n...

In this work, antioxidant hydrogels were prepared by the construction of an interpenetrating chitosan network and functionalization with gallic acid. The poly(2-hydroxyethyl methacrylate) p(HEMA)-based hydrogels were first synthesized and subsequently surface-modified with an interpenetrating polymer network (IPN) structure prepared with methacrylamide chitosan via free radical polymerization. ...
