Anti-inflammatory therapies currently in use mainly include steroidal and non-steroidal drugs. Contrary to their side effects, the steroid hormones glucocorticoids, which are synthetic versions of natural cortisol, are nevertheless often employed to treat a variety of inflammatory disorders. Other drug class of choice is non-steroidal drugs which mainly target COX-2 and hence the synthesis of prostaglandins, particularly PGE2.

Biopolymers such as chitosan and gum acacia are used for nanotechnological applications due to their biosafety and ecofriendly nature. The commercial fungicide mancozeb (M) was loaded into chitosan-gum acacia (CSGA) polymers to form nanocomposite (NC) CSGA-M (mancozeb-loaded) measuring 363.6 nm via the ionic gelation and polyelectrolyte complexation method.

Metal nanoparticles are well known for their antimicrobial properties. The use of metalbased nanoparticles in the agricultural field has considerably increased globally by both direct and indirect means for the management of plant diseases. In this context, the development of controlled delivery systems for slow and sustained release of metal nanoparticles is crucial for prolonged antimicrobial activity.

Nanotechnology is an interdisciplinary research field. In recent past efforts have been made to improve agricultural yield through exhaustive research in nanotechnology. The green revolution resulted in blind usage of pesticides and chemical fertilizers which caused loss of soil biodiversity and developed resistance against pathogens and pests as well.

The objective of the present study was to prepare ketoconazole loaded chitosan-gellan gum (CSGG) nanoparticles and to evaluate them for antifungal activity against Aspergillus niger. Ketoconazole loaded CSGG nanoparticles were prepared by electrostatic complexation technique using chitosan (CS) as cationic polymer and gellan gum (GG) as anionic polymer with ketoconazole as drug. It was observed that the effect of gellan gum on particle size was more pronounced in comparison to chitosan and increase in its concentration resulted in a significant increase in particle size but decrease in zeta potential.

Zinc oxide nanoparticles (ZnO nps) are known to be effective against a wide array of microorganisms. At nanoscale, they have higher toxicity and they need to be rendered less toxic and more biocompatible. To achieve this, ZnO nps were incorporated in nanohydrogel particles made out of sodium alginate/gum acacia and cross-linker glutaraldehyde in order to ensure their gradual and sustained release instead of burst release, and hence lowering their toxicity.
