About Cover

The cover photo describes the ring topological structure of carbon nucleus (using vortex-fractal-ring theory), which consists from two globules with 3 protons globule substructures. As discussed by, this vortex-fractal-ring theory is a new and original view of elementary particles and the structure of atomic nuclei, atoms, and molecules. Its basics are simple for understanding through the comprehensive topological structure that does not need description by complicated mathematical formulas. This theory together with grammatical evolution can design new models of nanostructures and allows us to understand the fundamental physical and chemical reasons for the stability and reactivity of atoms and molecules.

Abstract

Nanogel synthesis is gaining enormous interest in a large number of applications, such as drug delivery, wound care systems and tissue engineering. In the present work, we have investigated the preparation of Tragacanth gum (TG) nanoparticles in a water-in-oil nanoemulsion system. These nanoparticles exhibit stacked core-shell type of structure in which polygonal TG nanoparticles are covered by lipid structured lecithin (LC). The resultant nanoparticles comprise of amphillic nature, i.e. the hydrophilic TG core and hydrophobic LC shell which offers interesting features of immobilization of biomolecules.

Keywords

Tragacanth gum, lecithin, dioctylsulfosuccinate sodium salt, nanoemulsion, surfactant.
