Plant derived polymers like mucilage have evoked great attention in the field of functional food ingredient delivery. The objective of this study was to evaluate the potential of basil seed gum nanoparticles (BSG NPs) as an oral delivery system for glutathione (GSH). BSG NPs (1-0.25mgml) were fabricated by ion gelling technique and calcium was used as a cross-linking agent (0.7-0.3mgml). The results showed that BSG NPs (298-595nm) have spherical shape and the relative viscosity revealed that the possibility of agglomeration of BSG NPs is low. The interaction between BSG and GSH was confirmed by FTIR and DSC studies. Entrapment and loading efficiency of BSG-GSH nanoparticles were in the range of 6.5-43% and 7-13%, respectively. GSH release in gastrointestinal environment showed release speed in pH 1.2 was lower in compared with pH 6.8. As a result, smaller amounts of GSH will be destroyed in the stomach during digestion time.

The incorporation of carbohydrate polymers is one of the most efficient strategies to reinforce protein matrices for electrospinning application. In the present work, a basil seed gum (BSG)-reinforced whey protein isolate (WPI) was developed via electrospinning for the co-encapsulation of zinc oxide nanoparticles (ZnONPs) and curcumin (CU). The physicochemical attributes of the nanofiber samples could be controlled by varying the BSG mixing ratio.

In the treatment of tumor-targeted small-molecule anti-cancer drugs, antibody-mediated therapies, especially for antibody-drug conjugates (ADCs), have revealed great latent force. However, the therapeutic drugs provided by ADCs possess limitation. Considering that the combination of antibodies and nano-drugs can broaden their applicability in the field of tumor treatment, herein, we developed an antibody conjugated polymeric prodrug nanoparticles SAE-PEG--PBYP--CPT for targeted camptothecin (CPT) delivery to liver tumor cells.

Exposure to titanium dioxide (TiO2) nanoparticles (NPs) is associated with lung remodeling, but the underlying mechanisms are unknown. Matrix metalloprotease (MMP)-1 is an important actor in matrix homeostasis and could therefore participate in TiO2 NP effects. Our aim was to evaluate the effects of TiO2 NPs on MMP-1 expression and activity in lung pulmonary fibroblasts and to understand the underlying mechanisms and assess the importance of the physicochemical characteristics of the particles in these effects.
