Abstract: Fragrant and antimicrobial properties were conferred to cotton fabrics following microencapsulation using green materials. Limonene and vanillin microcapsules were produced by complex coacervation using chitosan/gum Arabic as shell materials and tannic acid as hardening agent. The effect of two emulsifiers; Span 85 and polyglycerol polyricinoleate (PGPR), on the encapsulation efficiency (EE %), microcapsule's size and morphology, and cumulative release profiles was studied. The use of Span 85 resulted in mononuclear morphology while PGPR gave rise to polynuclear structures, regardless of the core material (vanillin or limonene). The obtained microcapsules demonstrated a sustained release patter. Grafting of the produced microcapsules onto cotton fabrics through an esterification reaction using citric acid as anon-toxic cross-linker followed by thermofixation and curing, was confirmed by SEM and FTIR spectroscopy.

Abstract: A liposomal delivery composition to be administered through intravenous injection is provided for the treatment of cancer. The delivery composition has a liposome composition with therein encapsulated a first cancer drug (e.g. oxaliplatin) and a second cancer drug (e.g. ascorbic acid or satraplatin). The liposomal delivery composition has negative surface potentials resulting in an encapsulation efficiency for e.g. of oxaliplatin of about 20-25%. The liposomal delivery composition has a particle size of less than 200 nm. The liposomal delivery offers protection of the drug cargo, which reduces their non-intentional and non-pharmacological interactions thus reducing side effects and increases efficacy. Increased efficacy reduces the amount of drug given to a patient, which would reduce healthcare cost. The combinatory approach of two different drug cargos within the same liposome delivery composition allows for the synergistic action of these drugs.
