Recent development in nanoencapsulation and delivery of natural bioactives through chitosan scaffolds for various biological applications.

Nowadays, nano/micro-encapsulation as a pioneering technique may significantly improve the bioavailability and durability of Natural bioactives. For this purpose, chitosan as a bioactive cationic natural polysaccharide has been frequently used as a carrier because of its distinct chemical and biological properties, including polycationic nature, biocompatibility, and biodegradability. Moreover, polysaccharide-based nano/micro-formulations are a new and extensive trend in scientific research and development in the disciplines of biomedicine, bioorganic/ medicinal chemistry, pharmaceutics, agrochemistry, and the food industry.

Graphene quantum dot-porphyrin/phthalocyanine multifunctional hybrid systems: from interfacial dialogue to application.

Engineered well-ordered hybrid nanomaterials are symbolically at a pivotal point, just ahead of the long-anticipated transformation of the human race. Incorporating newer carbon nanomaterials like graphene quantum dots (GQDs) with tetrapyrrolic porphyrins (Pp) and phthalocyanines (Pc) is crucial for achieving exquisite molecular nanoarchitectures that are superior to their individual components. The outcomes of this, particularly in the case of graphene quantum dot-porphyrin/phthalocyanine (GQD-Pp/Pc) hybrids, remain comprehensively unexplored to date.
