A novel approach for the preparation of nano- and microcapsules in aqueous solutions by using thermoresponsive polymer (TRP) templates (mesoglobules) is described. The method comprised three steps: formation of mesoglobules, coating the templates by seeded radical copolymerization, followed by core dissolution and core removal upon cooling. When mesoglobule entraps biomacromolecules during the ...

Biomineralization is an extremely efficient biologically guided process towards the advancement of nano-bio integrated materials. As a prime module of the natural world, enzymes are expected to play a major role in biogenic growth of inorganic nanostructures. Although there have been developments in designing enzyme-responsive nanoparticle systems or generation of inorganic nanostructures in an...

Mannobiose-modified polyethylenimines (PEI) are used in gene therapy to generate nanoparticles of DNA that can be targeted to the antigen-presenting cells of the immune system. We report that the sugar modification alters the DNA organization within the nanoparticles from homogenous to shell-like packing. The depth-dependent packing of DNA within the nanoparticles was probed using AFM nano-inde...

introduction in this study, we describe the results of controlled synthesis and application of gold coated fe3o4/sio2 nano-shells combined with the optical property of gold for enhancement of selective photothermal interaction with cancerous cells based on the surface plasmon resonance (spr) phenomena. materials and methods magnetite nano-particles (mnps) were prepared by means of co-precipitat...

Alkynyl-terminated double hydrophilic ABC triblock copolymer, poly(oligo(ethylene glycol) monomethyl ether methacrylate)-b-poly(2-(dimethylamino) ethyl methacrylate)-b-poly(2(diethylamino) ethyl methacrylate) (alkynyl-POEGMA-b-PDMA-b-PDEA), was synthesized via atom transfer radical polymerization (ATRP) by sequential monomer addition using propargyl 2-bromoisobutyrate (PgBiB) as the initiator. ...

PVDF and P(VDF-TrFE) nano- and micro- structures have been widely used due to their potential applications in several fields, including sensors, actuators, vital sign transducers, and energy harvesters. In this study, we developed vertically aligned P(VDF-TrFE) core-shell structures using high modulus polyurethane acrylate (PUA) pillars as the support structure to maintain the structural integr...

Spontaneous emission (SE) rate and the fluorescence efficiency of a bare fluorescing nanoparticle and the nanoparticle with a silver nanoshell are analyzed rigorously by using a classical electromagnetic approach with the consideration of the nonlocal effect of the silver nano-shell. The dependences of the SE rate and the fluorescence efficiency on the core-shell structure are carefully studied...

Elastic theory of low-dimensional continua and its applications in bio-and nano-structures This review presents the elastic theory of low-dimensional (one-and two-dimensional) continua and its applications in bio-and nano-structures. First, the curve and surface theory, as the geometric representation of the low-dimensional continua , is briefly described through Cartan moving frame method. The...
