Innovative composite films of chitosan, methylcellulose, and nanoparticles [PDF]

open access: yes, 2011
Plastic is readily available and inexpensive, so it is becoming the main material for packaging. Unfortunately plastics do not biodegrade and, if reduced in small pieces, contaminate soil and waterways.

Thiolated Chitosans: Novel Polymers for Mucoadhesive Drug Delivery – A Review [PDF]

open access: yes, 2008
Chitosan is a natural polycationic copolymer consisting of glucosamine and N-acetylglucosamine units. The polymer has valuable properties as a biomaterial because it is considered to be biocompatible, biodegradable and non-toxic.

Liposomes coated with thiolated chitosan enhance oral peptide delivery to rats.

open access: yesJ Control Release, 2013
The aim of the present study was the in vivo evaluation of thiomer-coated liposomes for an oral application of peptides. For this purpose, salmon calcitonin was chosen as a model drug and encapsulated within liposomes. Subsequently, the drug loaded liposomes were coated with either chitosan-thioglycolic acid (CS-TGA) or an S-protected version of the ...
