Microencapsulation of garlic oil by β‑cyclodextrin as a thermal protection method for antibacterial action.

The present study investigated the encapsulation process of garlic oil in β‑cyclodextrin (βCD) and the antibacterial properties of the βCD-garlic oil complex against Escherichia coli and Staphylococcus aureus. The encapsulation method increased the thermal stability of garlic oil with a formation constant (Kc) value of 253.78 L·mol for of the βCD-garlic oil complex, which confirmed the success of the encapsulation process.

Microencapsulation of eugenol molecules by β-cyclodextrine as a thermal protection method of antibacterial action.

Eugenol is natural oil that has excellent antibacterial properties but cannot be used to fabricate many products that require thermal processing. One possible alternative to the use of the eugenol molecules in high-temperature processes is the encapsulation of these molecules in a structure that is not toxic and is resistant to thermal treatment. This work investigated the encapsulation process of eugenol molecules in β-cyclodextrine and the antibacterial properties of eugenol-β-cyclodextrine (the eugenol-βCD complex) against Escherichia coli and Staphylococcus aureus.

Application of glass particles doped by Zn(+2) as an antimicrobial and atoxic compound in LLDPE and HDPE.

This study demonstrates the potential application of glass particles doped with Zn(+2) (GZn) as an atoxic, antimicrobial additive when used in conjunction with high density polyethylene (HDPE) and linear low density polyethylene (LLDPE) polymers. Toxicity tests demonstrated that these modified glass particles were nontoxic to human cells, and atomic absorption analyses demonstrated the migration of ionic species in quantities less than 2.0ppm for both the HDPE/GZn and LLDPE/GZn compounds.

The influence of particle size and AgNO3 concentration in the ionic exchange process on the fungicidal action of antimicrobial glass.

Antimicrobial materials have long been used as an effective means of reducing the risks posed to humans by fungi, bacteria and other microorganisms. These materials are essential in environments where cleanliness, comfort and hygiene are the predominate concerns. This work presents preliminary results for the development of a fungicidal vitreous material that is produced by the incorporation of a silver ionic specimen through ionic exchange reactions.
