Brief Introduction

Astaxanthin is a natural nutritional component, it can be found as a food supplement. The supplement is intended for human, animal, and aquaculture consumption.

Astaxanthin is a carotenoid. It belongs to a larger class of phytochemicals known as terpenes, which are built from five carbon precursors; isopentenyl diphosphate and dimethylallyl diphosphate . Astaxanthin is classified as a xanthophyll (originally derived from a word meaning “yellow leaves” since yellow plant leaf pigments were the first recognized of the xanthophyll family of carotenoids), but currently employed to describe carotenoid compounds that have oxygen-containing moities, hydroxyl or ketone , such as zeaxanthin and canthaxanthin. Indeed, astaxanthin is a metabolite of zeaxanthin and/or canthaxanthin, containing both hydroxyl and ketone functional groups. Like many carotenoids, astaxanthin is a colorful, lipid-soluble pigment. This colour is due to the extended chain of conjugated (alternating double and single) double bonds at the centre of the compound. This chain of conjugated double bonds is also responsible for the antioxidant function of astaxanthin (as well as other carotenoids) as it results in a region of decentralized electrons that can be donated to reduce a reactive oxidizing molecule.

Function:

1.Astaxanthin is a powerful antioxidant and may protect against oxidative damage to body tissues.

2.Astaxanthin can improve the immune response by increasing the number of antibody producing cells.

3.Astaxanthin is a potential candidate to treat neurodegenerative disease such as Alzhimer and Parkinson diease.

4.Astaxanthin dan reduce UVA-light damage to skin such as sunburn, inflammation, ageing and skin cancer.

Application

1.When applied in pharmaceutical field, astaxanthin powder has the good function of antineoplastic;

2.When applied in health food field, astaxanthin powder is used as food additives for pigment and health care;

3.When applied in cosmetic field, astaxanthin powder has the good function of antioxidant and anti-aging;

4.When applied in animal feeds field, astaxanthin powder is used as animal feed additive to impart coloration, including farm-raised salmon and egg yolks.

Sprayable Antibacterial Film: A Nanosilver Composite
TEAM: Nathan Cloeter, Luis Correa, Benjamin Lee, Matt Reilly, Mercedes Valero

ABSTRACT: Recent studies suggest that cell phones are one of the surfaces with the most bacteria we encounter in our day, where it was shown that 1 in 6 cellphones are contaminated with fecal matter (Song). Silver nanoparticles have been shown to be highly efficient antibacterial nanoparticles, largely due to the oxidation and release of silver ions (Ferrer, Guo). Composite materials with antibacterial polymers and silver nanoparticles expand the applications of silver nanoparticles for antibacterial purposes, especially because they can be used as coatings for a variety of applications. These composites are beneficial because the nanoparticles can prevent bacterial growth while the polymer can prevent bacterial adhesion. This design takes advantage of the inherent antibacterial properties of chitosan, a polysaccharide extracted from shrimp shells, and the silver nanoparticles to produce a chitosan based polymeric coating with enhanced antibacterial properties. In the design, the properties of the sprayable solution, the nanoparticle formation kinetics and the film properties were studied. We also report on the results from the preliminary prototyping and antibacterial testing of films designed to be applied to the Aluminum back of the iPhone 5.
