Abstract:
The objective of the study was to obtain multifunctional core shell nanostructures of superparamagnetic iron oxide nanoparticles (Fe3O4) coated with various ionic biopolymers that can optimize toxicity to healthy cells, colloidal instabilities and drug loading capacities. These nanostructures can also allow drug delivery to tumor tissue because of their magnetic properties, accumulation and drug release at tumor site could be controlled by means of an external magnetic field. The impact of the biopolymers with different ionic properties to final core shell structures were investigated and compared in terms of their colloidal properties, cytotoxicities, drug adsorption and drug delivery capacities. Besides, the effect of the surface charges on the healthy cells and cancer cells is very important factor affecting toxicity and drug delivery. The results showed that the drug delivery agents coated with cationic biopolymers with cationic surface properties significantly reduced cancer cell viability compared to the anionic and nonionic polymer coatings even though their drug loading capacities were found to be the lowest.

Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
