Journal Article
Lipid-based colloidal carriers for peptide and protein delivery – liposomes versus lipid nanoparticles
TL;DR: Strategies used for formulation of peptides and proteins, methods used for assessment of association efficiency and practical considerations regarding the toxicological concerns are described.
Journal ArticleDOI
Novel resveratrol nanodelivery systems based on lipid nanoparticles to enhance its oral bioavailability
TL;DR: In this paper, the authors developed two resveratrol nanodelivery systems based on lipid nanoparticles to enhance the oral bioavailability for further use in medicines, supplements, and nutraceuticals.
Journal Article
Oral insulin delivery by means of solid lipid nanoparticles.
TL;DR: Results demonstrated that SLN promote the oral absorption of insulin, and the potential of these colloidal carriers for oral administration was evaluated.
Journal ArticleDOI
Development and Comparison of Different Nanoparticulate Polyelectrolyte Complexes as Insulin Carriers
Bruno Sarmento,Sandra Martins,António J. Ribeiro,Francisco Veiga,Ronald J. Neufeld,Domingos Ferreira +5 more
TL;DR: In this paper, a polyanion/chitosan nanoparticulate oral delivery system for insulin was developed, which was formed by ionotropic complexation and coacervation between polyanions (dextran sulfate and alginate).
Journal ArticleDOI
Solid lipid nanoparticles as intracellular drug transporters: an investigation of the uptake mechanism and pathway.
Sandra Martins,S. Costa-Lima,T. Carneiro,Anabela Cordeiro-da-Silva,Eliana B. Souto,Domingos Ferreira +5 more
TL;DR: The results suggest that SLN can be a promising alternative in brain tumours treatment and find the mechanism of internalisation was found to be mainly through a clathrin-dependent endocytic pathway.
