Chitosan is a natural polymer with acceptable biocompatibility, biodegradability, and
mechanical stability; hence, it has been widely appraised for drug and gene delivery …

Chitosan is a product of the deacetylation of chitin, which is widely found in nature. Chitosan
is insoluble in water and most organic solvents, which seriously limits both its application …

Chitosan (CS) is a linear polysaccharide obtained by the deacetylation of chitin, which, after
cellulose, is the second biopolymer most abundant in nature, being the primary component …

In this work, a novel engineered biochar prepared through modification with chitosan and
pyromellitic dianhydride (PMDA) was investigated as an adsorbent for the removal of heavy …

In recent decades, drug delivery systems (DDSs) based on nanotechnology have been
attracting substantial interest in the pharmaceutical field, especially those developed based …

Oral colon-targeted delivery systems (OCDSs) have attracted great attention in the delivery
of active compounds targeted to the colon for the treatment of colon and non-colon diseases …

In case of colon-specific delivery of therapeutic agents through oral route, microbial/enzyme-
triggered release approach has several advantages over other approaches due to unique …

Chitosan (CS) is a biologically active biopolymer used in different medical applications due
to its biodegradability, biocompatibility, and nontoxicity. Nanotechnology is an exciting and …

Chitosan (Ch), a linear cationic biopolymer, has broad medical applications. In this paper,
new sustainable hydrogels (Ch-3, Ch-5 a, Ch-5 b) based on chitosan/sulfonamide …

Guar gum succinate− sodium alginate (GGS-SA) beads cross-linked with barium ions were
prepared and characterized as a pH sensitive carrier for colon-specific drug delivery. The …
