Starch coating

The biological impact of starch capped copper nanoparticles on mouse embryonic fibroblast (3T3L1) cells in vitro) was also evaluated by various parameters. More than 85 % of the 3T3Llcells were found to be viable, even after 20 hours time exposure which implies minimum impact on cell viability and morphology. The study demonstrates dose dependent cytotoxic potential of SCuNPs, that is non cytotoxic in the nanogram dose and moderately cytotoxic in the microgram doses (Fig. 10). Comparison of SCuNPs with Cu ions and uncapped copper nanoparticles (UCuNPs) revealed that, ions are more cytotoxic than SCuNPs. This observation supports the theory of slow release of ions from starch coated nanoparticles. 

A leuco dye(s) solution in a nonvolatile solvent is encapsulated in microcapsules 5-10 pm in diameter, and after addition of latex and wheat starch, coated (at about 5 g/m2 as dry solid) on a substrate such as paper, synthetic paper, or plastic film, and dried to give the CB sheet. 

Kosaraju et al., 2006), as well as to encapsulate probiotic cultures (Fei-joo et al., 1997) and to make vitamin E nanoparticles (100 nm) stabilized by a starch coating suitable for fortified beverages (Chen and Wagner, 2004). And, by using microfluidization followed by solvent evaporation, Tan and Nakajima (2005) have reported preparation of (3-carotene nanodispersions (60-140 nm). 

The film-forming characteristics of starch have been used for many years. Numerous products can be protectively and decoratively coated with starch. Starch can be added to sugar solutions to provide a less brittle and moisture-sensitive surface. Starch coatings have the advantage of being oil and grease resistant. 

The first clinical human trials using magnetic hyperthermia were reported by Liibbe, et al. [70, 129, 137, 190] who used 100-nm starch-coated iron-oxide particles bound with epirubicin for treatment of advanced solid cancers. Jordan recently reported positive results from ongoing trials of advanced cancer patients who received magnetic nanoparticle hyperthermia in conjunction with conformal external beam radiation therapy [191]. The therapy was well tolerated by the patients and significant increases in the length and quality of life were observed. 

Functions as an emulsifier of oils and fats in the manufacture of fluid or paste emulsions for industrial lubricants, consumer products, and textile lubricants and softeners. This waxy lipophilic surfactant is also used as a thickening agent and stabilizer for starch coatings on paper, and as a water dispersible paper size. EMEREST 2640 is also a good lubricant for channeling wire through conduit.

However, if a small amount of colloidal silica is added, the negatively charged silica particles flocculate the excess starch as well as the starch coated fibers. The large floes of fibers are readily and efficiently filtered from the water. In addition, the floes of excess starch are trapped within the fiber matrix where they can act as binder. This increased efficiency in filtration has the effect of leaving the water phase much less contaminated with libers and starch which presents much less of a disposal problem. This is illustrated in Figure 12.52 and Figure 12.53.

Shasha and Whistleb [13] prepared an inexpensive coating of Cehte 535 utilizing potato starch as a binder. Chromatoplates prepared with the Celite 535-starch coating gave an excellent resolution of a simple mixture of L-rhanmose (hi / 92), D-ribose (hi / 50), D-fructose (hi / 31), D-glucose (hi / 28) and maltose (hi / 12) with isopropanol-water (90 H- 10) (solvent XIV).
