ANasal Spray for Sinusitis & Hay Fever (article)
ChitoRhino Mist is a natural nasal mist spray designed to provide relief of the sinuses from airborne irritants such as pollen, allergens, pollutants and fungal spores. ChitoRhino spray contains a natural compound, Chitosan, which is derived from the shells of shrimps and crabs. Chitosan, a complex sugar, is the second most abundant polysaccharide after cellulose which is found in plants.

The KytoStat Bandage has a unique pad that is fabricated from chitosan, a naturally occurring material derived from shrimp shells. Once in bandage form, it is joined with a latex free adhesive backing and is then sterilized.
Is there a problem using HemCon products on people with shrimp or shellfish allergies?
There have been no known allergic reactions as a result of using the HemCon Bandage since distribution began in 2003 and there have been no adverse effects reported in over 1,000,000 bandages shipped.
HemCon Medical Technologies, Inc. has results from a shellfish allergy study conducted by its chitosan supplier which demonstrates that, out of 221 individuals with suspected hypersensitivity, including 8 individuals with known shellfish allergies, none demonstrated any dermal sensitivity when pricked with a chitosan test solution. However, since chitosan is extracted from the shells of shrimp and other shellfish, individuals with known shellfish allergies should exercise caution in the use of products containing chitosan.
Shrimp-shell wound healant to get space test
A biopolymer produced from shrimp shells that has proved invaluable in treating wounded soldiers will be put to a new test in August – aboard the space shuttle Endeavour.
Adhesives That Replace Stitches
'Glue Produced by Shellfish May Replace Surgical Stitches (article)
Using the natural glue that marine mussels use to stick to rocks, and a slightly modified inkjet printer, a team of
researchers from North Carolina State University in the US has devised a new way of making medical adhesives that could replace
traditional sutures and result in faster healing, less scarring and increased precision for exacting operations such as

Hem Com Bandages
FAQ page: "From what is the HemCon Bandage comprised?
The HemCon Bandage is fabricated from chitosan, a naturally occurring, biocompatible polysaccharide derived from
shrimp shells. The shrimp shells are processed and chemically treated. Once in bandage form, they are sterilized.
Is there a problem using this product on people with shrimp or shellfish allergies?
There have been no known allergic reactions as a result of using the HemCon Bandage since distribution began in 2003 and
there have been no adverse effects reported in over 700,000 bandages shipped.

Grant to fund study of possible asthma treatment from crabs (article)
The title of his research is "Oral Administration of N-acetyl-D-glucosamine Polymer Particles Down-Regulates Airway Allergic Responses." It focuses on finding a way to decrease asthma attacks in children by boosting their immune systems by introducing carbohydrates purified from crab and shrimp shells.
Biomedical Textiles Article
Biomedical textiles from dibutyrylchitin and chitin
"On the European market there is a lack of innovative biomaterials that aid in regeneration of wound tissue. The project:
aims the design and development: of optimal textile forms for medical applications made from dibutyrylchitin (DBC) and
chitin, from fishery byproducts. Recently a method for the synthesis of dibutyrylchitin is developed. DBC is
easily soluble in common recyclable solvents and has film/fibre forming properties. Chitin can be regenerated (RC).
The products are assumed to have wound healing properties. This opens the way for the development of novel functional
biomaterials made from DBC and RC. Technologies for the production of fibres, yarns, non-wovens and knittings will be
developed. The textiles will be designed to requirements and characterised on mechanical, physico-chemical and
biochemical-medical (in vitro, in vivo) properties. Initiations for approval of medical products will be made.

Chitosan Composites for Bone Tissue Engineering—An Overview
Chitosan (CTS) and hydroxyapatite (HAp) are among the best bioactive biomaterials in bone tissue engineering and renowned for their excellent biocompatibility with the human body environment
From shrimp shells to cancer cells: a biotech challenge (article)
The participants also discussed specific chitosan to aid in the transport of drugs to target sites, such as brain or cancer cells. A big advantage is that chitosans are well tolerated by the human body and easily biodegradable.
Glucose Sensing Sponge Delivers Insulin Precisely When and Where Needed (article)
The researchers created a spherical, sponge-like matrix out of chitosan, a material found in shrimp and crab shells. Scattered throughout this matrix are smaller nanocapsules made of a porous polymer that contain glucose oxidase or catalase enzymes. The sponge-like matrix surrounds a reservoir that contains insulin. The entire matrix sphere is approximately 250 micrometers in diameter and can be injected into a patient.
Injectable 'smart sponge' controls diabetes, presents new targeted drug delivery method (article)
Take, for example, this new method developed by North Carolina State University researchers that uses injectable sponge to control blood sugar levels. No, it's not the same sponge you use to clean at home -- the material is made out of a substance taken from crab and shrimp shells called chitosan. This spongy material forms a matrix that's approximately 250 micrometers in diameter, where a rise in blood sugar causes a reaction in the pores that leads to the drug's release.
