Nanomaterials can be used as drug carriers with multiple features, including target delivery triggered by environmental, pH, thermal responses, enhanced biocompatibility, and the ability to cross the blood-brain barrier. Chitosan (CS) is a natural polysaccharide largely obtained from marine crustaceans. It provides drug delivery vector for therapeutic CS and diagnostic CS, owing to its biocompatibility, biodegradability, low toxicity, and structural variability. Derivatives of CS such as quaternized CS, thiolated CS and carboxylated CS have enhanced its effectiveness in oral absorption of macromolecular drugs. This review discusses different forms of nanomaterials generated from CS and its derivatives for controlled drug delivery.

Copolymerization Reaction

Polycarboxylate-based superplasticizers are synthesized by radical graft copolymerization reaction, and the products are divided into ester series (PC-1) and ether series (PC-2) on the basis of different big monomers. This article studies on influence of the different composition and dosages of the synthetic superplasticizers in the self-compacting concrete (SCC). The results show that the requirements of SCC workability can be achieved through simple adjustment kinds and dosages of the synthetic superplasticizers under the given mix proportions and the raw materials. And the main mechanism of the polycarboxylate-based superplasticizers is steric hindrance effect.
