Abstract
Background: Açaí berry, from the Euterpe oleracea Mart. Palm, has been described as the most important fruit in the Brazilian Amazon. Several studies have reported that anthocyanins (ACNs), one of the components of the açaí, have enormous potential for pharmaceuticals applications. However, the bioavailability of anthocyanins is relatively low compared to that of other flavonoids. Then, in the present work, anthocyanins-loaded nanoparticles have been developed to overcome their poor bioavailability.
Methods: A two-level factorial design with three factors was considered to evaluate the effect of EUDRAGIT ® L100, polyethylene glycol 2000 (PEG 2000) and polysorbate 80 on encapsulation efficiency (EE) of anthocyanins. Also, major parameters of nanoparticles were assessed by using mainly SEM microscopy and Dynamic light scattering.
Results: PEG 2000 was the only individual factor that has statistical significance (95% confidence level). The process yields (PY) were found in between 67% and 92%; the particle size and morphology analysis showed two distribution size, one for NPs and another for the agglomerates.
Conclusion: The pH-sensitive polymer together with the hydrophilic polymer showed to be suitable as ACNs delivery system. The delayed release profile of ACNs, observed for all formulations, can enhance their poor bioavailability. Nevertheless, ACNs bioavailability in vivo remains to be studied.
Keywords: Anthocyanins, bioavailability, nanoparticles, phytochemicals, polymeric coatings.

Advances of natural products, bio-actives and novel drug delivery system against emerging viral infections
Due to the increasing prevalence of viral infections and the ability of these human pathogens to develop resistance to current treatment strategies, there is a great need to find and develop new compounds to combat them. These molecules must have low toxicity, specific activity and high bioavailability. The most suitable ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
