Nanocapsules that can be tailored intelligently and specifically have drawn considerable attention in the fields of drug delivery and bioimaging. Here we conduct a theoretical study on cell uptake of a spherical nanocapsule which is modeled as a linear elastic solid thin shell in three dimensions. It is found that there exist five wrapping phases based on the stability of three wrapping states:...

The synthesis of polymeric nanocapsules in the approximate diameter range 40-100 nm (TEM/SEM) using catanionic surfactant vesicle templates stabilized by subcritical CO2 is demonstrated. Near equimolar aqueous solutions of the surfactants sodium dodecyl sulfate (SDS) and dodecyltrimethylammonium bromide (DTAB) experienced immediate vesicle destabilization and precipitation in the absence of CO2...

Current strategies to improve wound healing are often created from multiple components that may include a scaffold, cells, and bioactive cues. Acellular natural hydrogels are an attractive approach since the material's intrinsic biological activity can be paired with mechanical properties similar to soft tissue to induce a host's response toward healing. In this report, a systematic evaluation ...

Self-sustaining enzyme nanocapsules were prepared by the interfacial crosslinking of enzymes droplets. They acted both as nanoreactors and a transport module, used to reagents perform reactions in different environments.

In this study, n-dodecanol and 1-tetradecanol were nanoencapsulated by poly(methyl metharcylate-co-methacrylic acid) (p(MM-co-MA)) wall using emulsion polymerization method which was defined as one-stage (OS) or two-stage (TS). Nanocapsules analyzed Fourier-transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM), differential scanning calorimeter (DSC) thermogravimetric ...

The present work describes the synthesis and characterization of PLA-co-EC copolymer from lactic acid and ethyl cellulose by azeotropic dehydration, under reduced pressure, at 140oC for 8 hours. The prepared PLA-co-EC copolymer was used for controlled drug release for an anticancer drug namely 6-Thioguanine with gold nanoparticles. Anticancer drug containing PLAco-EC copolymer nanocapsules were...

Direct excitation of acenaphthylene molecules included in a syn fashion within the octa acid nanocapsule dimerizes quantitatively to a syn dimer, and upon triplet sensitization, yields both syn and anti dimers probably by reacting within and outside the capsule.

Living organisms compartmentalize their catalytic reactions in membranes for increased efficiency and selectivity. To mimic the organelles of eukaryotic cells, we develop a mild approach situ encapsulating enzymes aqueous-core silica nanocapsules. In order to confine sol-gel reaction at water/oil interface miniemulsion, introduce an aminosilane precursors, which serves as both catalyst amphiphi...
