Due to their properties such as superparamagnetism, high surface area, large surface-to-volume ratio, easy separation under external magnetic fields, iron magnetic nanoparticles have attracted much attention in the past few decades. Various modification methods have been developed to produce biocompatible magnetic nanoparticles for protein immobilization. This review provides an updated and int...

We present the first detailed experimental observation and analysis of nanoparticle electrophoresis through a nanochannel obtained with synchronous high-bandwidth electrical and camera recordings. Optically determined particle diffusion coefficients agree with values extracted from fitting electrical transport measurements to distributions from 1D Fokker-Planck diffusion-drift theory. This comb...

Magnetic nanocomposites are an important class of advanced functional materials on the basis of a magnetic material and a matrix. To achieve unique mechanical, physical, chemical, and biomedical properties, one must be able to tailor only the surface structures of a nanoparticle. This requires the deposition of ultrathin and uniform films using the possibility offered by cold-plasma polymerisat...

We report the thermal degradation of a solid film of polypropylene carbonate, driven by the photothermal effect of gold nanoparticles. We provide characterization of the products of this chemical reaction and use the known activation barrier for this chemical reaction to discuss the temperatures obtained in the film. In addition, we report the efficiency of the reaction as a function of nanopar...

Due to their non-toxic nature, biodegradability and production from renewable resources, research has shown an increasing interest in the use of biosurfactants in a wide variety of applications. This paper reviews the characterization of rhamnolipid and sophorolipid biosurfactants based on their hydrophilicity/hydrophobicity and their ability to form microemulsions with a range of oils without ...

The quantitative assembly and disassembly of a new type of dynamic covalent nanoparticle (NP) building block is reported. In situ spectroscopic characterization reveals constitutionally adaptive NP-bound monolayers of boronate esters. Ditopic linker molecules are used to produce covalently connected AuNP assemblies, displaying open dendritic morphologies, and which, despite being linked by cova...

Dealloyed Pt core-shell nanoparticles constitute the most active and stable bimetallic oxygen reduction catalysts for low-temperature fuel cells. Here, we review recent advances on their preparation, structural characterization, and electrocatalytic performance. Starting with bimetallic metal overlayer model systems, for which we illustrate fundamental principles of the ORR activity enhancement...

This Account reports the synthesis and characterization of dendrimer-encapsulated metal nanoparticles and their applications to catalysis. These materials are prepared by sequestering metal ions within dendrimers followed by chemical reduction to yield the corresponding zerovalent metal nanoparticle. The size of such particles depends on the number of metal ions initially loaded into the dendri...
