“…Furthermore, the swelling power (SP) and water solubility (WS) of banana starch and the loaded and unloaded starch nanoparticles were studied and the results are shown in Table . All nanoparticle systems showed greater SP and WS values than the native banana starch – a behavior that has been reported for native cassava and starch nanoparticles and can be attributed to the lower crystallinity and lower polymerization of the smaller particles . Table also shows a significant difference ( P < 0.05) in the SP and WS of the native and cross‐linked nanoparticles, with CABSNps showing higher values.…”

BACKGROUND Starch nanoparticles have become among the most interesting nanovehicles for drug delivery because of their relatively easy synthesis, biocompatibility, and numerous botanical sources. Starch nanoparticles obtained from green bananas were cross‐linked with citric acid and loaded with β‐carotene. RESULTS Mean particle size, encapsulation efficiency, and β‐carotene release in simulated gastric and intestinal fluids and food simulants were studied. Cross‐linked nanoparticles showed higher loading efficiency and encapsulation capacity, indicating that they can accommodate more molecules than their unmodified counterparts, while mathematical models showed a diffusion of released β‐carotene into food simulant media. CONCLUSIONS Cross‐linked nanoparticles showed more controlled release under gastric conditions, mainly in the simulated intestinal fluid, indicating that they are suitable as vehicles for intestine‐specific targeting. This controlled released was also observed in food simulants, with lower release values in the more aqueous simulants. © 2019 Society of Chemical Industry

“…Incorporating nanosize additives in paint provide effective barrier performance, reduce the amount of holiday in paint and also enhance the integrity and durability of paint, since the fine particles dispersed in paint can fill cavities. Research has been carried out on cassava starch as green corrosion inhibitors [7], and the modification of cassava starches as potential corrosion inhibitors has been used on steel rods. Cassava starch which is sometimes a waste in most cassava processing plants, shows considerable improvement in the prevention of corrosion [8].…”

Internal and external corrosion affects oil and gas pipelines and were discussed in this chapter. Corrosion inhibitors are one of the methods that can be used to achieve corrosion control and prevention. The main discussion in this chapter was the use of cassava plant (Manihot esculenta Crantz) extract nanoparticles (CPENPs) as an additive in coatings to serve as a green corrosion inhibitor for oil and gas pipeline. Trace elements, such as O, Si, Ca, K, Fe and S, which are hetero-atoms, have been identified in CPENPs. Elements like Si and Ca would also improve the strength of coatings as well as reduce corrosion rate of coated metals. It has also been revealed that CPENPs is composed of the following compounds SiO 2 , CaCO 3 , Ca 2 (SO 4 ) 2 H 2 O and CaC 2 O 4 (H 2 O), which would help in improving the mechanical properties of alloys, composites and coatings. SiO 2 if added to coatings will improve the coating hardness, while the presence of CaCO 3 in coatings will form a precipitate that will serve as a protective film on the surface of the metal, thereby protecting the metal from corrosion. The nature of bond and organic compounds that exist in the CPENPs was also discussed.

A hydrophobic starch derivative is used for safe and enhanced delivery of anticancer agents. The synthesis and characterization of propyl starch with a controlled degree of substitution to modulate the release of the encapsulated hydrophobic drug is reported. The application of this polymer for formulating nanoparticles of docetaxel, an anti-cancer agent effective against numerous types of cancers but possessing intrinsic formulation difficulties is described. The solvent emulsification/diffusion technique is used and the synthesis is optimized with respect to several formulation parameters. Uptake studies with these nanoparticles indicate their enhanced internalization by the cancerous cells and their peri-nuclear localization.
