Abstract: Provided are a polysaccharide composition and method capable of reducing, whether during pre-wear immersion or during post-wear cleaning, the amount of protein adsorbed on hard contact lenses and orthokeratology lenses. The polysaccharide composition and method reduce the amount of protein adsorbed on hard contact lenses and thereby prevent corneal abrasions and inflammations of the conjunctiva and cornea.

Abstract: A method of using biopolymer to synthesize titanium-containing silicon oxide material and applications thereof are disclosed. The method comprises steps: mixing a titanium source, a silicon source, an acid source, a base source, a biopolymer and a solvent to form an aqueous solution, and letting the aqueous solution react to form a semi-product; performing aging, solid-liquid separation and drying of the semi-product to obtain a dried solid; and performing calcination or extraction of the dried solid to obtain a titanium-containing silicon oxide material with a high specific surface area. The present invention adopts a biopolymer as the templating agent, which makes the fabrication process of titanium-containing silicon oxide material more environment-friendly. After calcination or extraction, the product still has superior catalytic activity, able to catalyze epoxidation of olefins and favorable for the production of epoxide.
