In the research field of nanoparticles, many studies demonstrated a high impact of the shape, size and surface charge, which is determined by the functionalization, of nanoparticles on cell viability and internalization into cells. This work focused on the comparison of three different nanoparticle types to give a better insight into general rules determining the biocompatibility of gold, Janus...

BACKGROUND The purpose of this work is to provide experimental evidence on the interactions of suspended nanoparticles with artificial or biological membranes and to assess the possibility of suspended nanoparticles interacting with the lipid component of biological membranes. METHODS 1-Palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) lipid vesicles and human red blood cells were incubat...

An efficient and versatile strategy is presented to modulate the magneto-heating performance of a nanoparticle system, which consists mixing nanoparticles with different shape size exploiting magnetic interaction between them.

This article reports a simple, versatile approach to the fabrication of lithographically defined mesoscopic colloidal silica nanoparticle patterns over large areas using spin-coating, interferometric lithography, and reactive-ion etching. One-dimensional nanoparticle films (bands) and 2D discs, diamonds, and holes with sub-micrometer periodicity, high quality, and excellent uniformity were succ...

Nanomaterials are widely used as pseudostationary and stationary phases in electrically driven separations. The advantages of using nanomaterials are numerous including tunable sizes, multiple core compositions, flexible injection schemes, and diverse surface chemistries. Nanomaterials, however, exhibit large surface energies which induce aggregation and may yield unpredictable function in sepa...

The purpose of this study was to design and evaluate a novel target nanoparticle for disease detection and drug delivery using the biotin-avidin binding system. The formed lectin-conjugated chitosan fluorescent nanoparticles were of spherical shape(100-200 nm in diameter), which were more stable under light than pure fluorescein isothiocyanate (FITC).
