Nanomanufacturing of nanoparticles is critical for potential translation and commercialization. Continuous flow devices can alleviate this need through unceasing production of nanoparticles. Here we demonstrate the scaled-up production of spherical nanoparticles functionalized with biomedical cargos from the rod-shaped plant virus tobacco mosaic virus (TMV) using a mesofluidic, continued flow m...

We analyze the enhancement in optical absorption of an absorbing medium when spherical metal nanoparticles are embedded in it. Our analysis uses generalized Mie theory to calculate the absorbed optical power as a function of the distance from the metal nanoparticle. This analysis is used to evaluate the potential of enhancing optical absorption in thin-film solar cells by embedding spherical me...

We present a molecular dynamics study on the self-assembly of anisotropic nanoparticles—triangles and tetrahedrons on a flat surface. We observe ordered and disordered aggregates of nanoparticles depending on the particle–particle and surface–particle interactions. Anisotropic particles induce directionality in the assembly process. In particular, a cross over from the isotropic (spherical) ass...

When nanoparticle self-assembly takes place in an anisotropic liquid crystal environment, fascinating new effects can arise. The presence of elastic anisotropy and topological defects can direct spatial organization. An important goal in nanoscience is to direct the assembly of nanoparticles over large length scales to produce macroscopic composite materials; however, limitations on spatial ord...

A derivation of chemical equilibrium equations for a spherical thin film of solution around a soluble solid nanoparticle is presented. The equations obtained generalize the Gibbs-Kelvin-Kohler and Ostwald-Freundlich equations for a soluble particle immersed in the bulk phase. The generalized equations describe the dependence of the chemical potentials of a condensate and dissolved nanoparticle ...

Understanding the influence of macromolecular crowding and nanoparticles on the formation of in-register β-sheets, the primary structural component of amyloid fibrils, is a first step towards describing in vivo protein aggregation and interactions between synthetic materials and proteins. Using all atom molecular simulations in implicit solvent we illustrate the effects of nanoparticle size, sh...

decade, [ 15 ] beginning with the use of fi bers as mounting structures [ 16–19 ] and progressing onto the use of scanning probe microscopy (SPM) tips. [ 6,8,13,20,21 ] While mounting nanoparticles onto SPM tips is more diffi cult than with fi bers the additional capabilities of the SPM tip have made such tips desirable. However , these tips typically require complicated assembly processes to p...

In this work, we study the bandgap change of a spherical semiconductor nanoparticle in an elastic matrix under framework linear elasticity. There are two important ratios – one is ratio interface energy between nanoparticle-solution and nanoparticle-matrix interface, other modulus matrix. Without external loading, dependent on both ratios. Under hydrostatic strain or simple shear strain, decrea...

UNLABELLED This study centers on the use of a nanoparticle based on the polysaccharide from Angelica sinensis (ASP) as an efficient and safe non-viral gene vector. After modification with branched low molecular weight polyethylenimine (1200 Da), the cationized ASP (cASP) was combined with the plasmid encoding transforming growth factor-beta 1 (TGF-β1) to form a spherical nano-scaled particle (i...
