Abstract Additive manufacturing (AM) also known as 3D printing (3DP) has become a popular technology with wide range of applications, from which vat photopolymerization is technique for producing nanocomposites controlled mechanical, thermal, and electrical properties. This uses UV light laser to cure liquid resin into solid object, layer by layer, allowing complex three-dimensional (3D) objects intricate details excellent finishing. Nanocomposites produced have been used in aerospace, automotive, medical industries, due their superior mechanical strength dimensional accuracy. In this article, we will discuss the advantages other aspects made photopolymerization, exploring potential research different areas, such AM technologies materials Graphical abstract review deals additive (3D printing), presenting systematic on technology, including technologies, materials,

This review provides an analysis of experimental results on the study alkaline heterogeneous deacetylation chitin obtained by authors and also published in literature. A detailed reaction kinetics was carried out considering influence numerous factors: reversibility, crystallinity porosity chitin, changes morphology during washing, alkali concentration, diffusion hydroxide ions, hydration reacting particles. mechanism for is proposed, taking into account its kinetic features which decisive role assigned to effects hydration. It has been shown that rate increases with a decrease degree ions concentrated solution. When concentration less than limit complete hydration, practically does not occur. Hypotheses have put forward explain second flat portion curve. The first hypothesis formation “free” water, leading molecules rate. postulates stable amide anion chitosan, prevents nucleophilic attack macromolecule ions.

Despite recent advances, cancer remains the primary killer on a global scale. Numerous forms of research have been conducted to discover novel and efficient anticancer medications. The complexity breast is major challenge which coupled with patient-to-patient variations heterogeneity between cells within tumor. Revolutionary drug delivery expected provide solution that challenge. Chitosan nanoparticles (CSNPs) prospects as revolutionary system capable enhancing activity reducing negative impacts normal cells. use smart systems (SDDs) delivering materials improve bioactivity NPs understand intricacies has garnered significant interest. There are many reviews about CSNPs present various points view, but they not yet described series in therapy from cell uptake death. With this description, we will more complete picture for designing preparations SDDs. This review describes SDDSs, targeting stimulus response using their mechanism. Multimodal chitosan SDDs medication therapeutic results.

Abstract Growing concerns about the harmful impact of synthetic polymers on environment and living organisms have shifted attention towards biopolymers which are environment‐friendly biocompatible. Biopolymers represent attractive sustainable biodegradable alternatives for replacing commercial polymers. Chitosan is one most prevalent available Earth. an alkaline cationic polymer, deacetylated form chitin. possesses excellent physicochemical properties such as biocompatibility, biodegradability, nontoxic, nonallergenic, biologically active molecules. During recent years, there has been a surge in demand chitosan various fields, however, due to poor water solubility mechanical properties, applications limited some extent. Strong inter intramolecular hydrogen bonds matrix make it highly crystalline, reducing its solubility. Chemical modification by technologies reported improve other characteristics, expanding application areas. Details chemical reactions involved focused this paper. The role chitin deacetylase enzyme discussed. This review aims provide insight into developments functionalization, development derivatives applications.
