As hydrophobic drug carriers, chitosan (CS) and Starch (SR) were copolymerized as biodegradable nanohydrogel and were functionalized with pthalic-anhydride and hexamethylenetetramine via 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide catalyzed coupling, respectively. The structure, morphology, physicochemical and drug loading performance of native and functioned hydrogel were investigated by using several characterization techniques. With the successive functionalization the significant properties like porosity increases and crosslinking density decreases due to the formation of hydrophilic contacts with aqueous solutions. The FESEM analysis revealed the hydrogel matrices with uniform particle size, porosity and deep pores with high internal surface area for extreme swelling and interacting with the drug and biomolecules for efficient drug administration. The effect of induced functionalities on the physicochemical performance and release of hydrophobic- anionic model drug (Bromocresol green) were studied at physiological conditions. The drug release capability of the synthesized nanohydrogel was increased from 65% to 80% and 85% by successive functionalization. The drug administration in selective hydrogel was not significant, presumably due to stronger H-bonding and entanglement within the system which was finely tuned by the induced hydrophilic, flexible and biocompatible functionalities in term of extended interfaces for the drug solutions. The physicochemical and electrokinetic performances suggested the selective hydrogel as promising carriers for the hydrophobic- anionic drugs at physiological conditions.

Primary Amino

Glutaraldehyde is a useful tissue and molecular fixing reagents. The aldehyde moiety reacts mainly with primary amino groups to form a Schiff's base, which is reversible but reasonably stable at pH 7; a stable covalent bond may be formed by reduction with, e.g., sodium cyanoborohydride (Fig. 1). The bifunctional glutaraldehyde, (CHO-(CH2)3-CHO), successfully stabilizes protein molecules due to generally plentiful amines on their surface; bovine serum albumin has 60; 59 lysines + 1 α-amino. With some enzymes, catalytic activity after fixing is preserved; with respect to antigens, glutaraldehyde treatment can compromise their recognition by antibodies in some cases. Complicating the chemistry somewhat are the reported side reactions, where glutaraldehyde reacts with other amino acid side chains, cysteine, histidine, and tyrosine. It has also been reported that glutaraldehyde can polymerize in aqueous solution. Newer crosslinkers have been found that are more specific for the amino group, such as the N-hydroxysuccinimide esters, and are commonly preferred for forming conjugates. However, most of these linkers hydrolyze in solution, so that the activity is lost over several hours, whereas the aldehyde group is stable in solution, and may have an advantage of overall efficiency.
