Preparation and evaluation of adipic dihydrazide cross-linked hyaluronic acid microspheres for cephalexin

Preparation and investigation of cross-linked hyaluronic acid nanoparticle systems

Preparation of enzyme conjugate through adipic acid dihydrazide as linker and its use in immunoassays.

The direct coupling of the carboxylic derivative of steroids to the amino group of enzymes is a well-established method in steroid enzyme immunoassays for making enzyme conjugates (1). Horseradish peroxidase (HRP), containing six lysine residues in the sequence, is a widely used enzyme in enzyme immunoassays; in practice, however , only one or two of these are generally available for reaction (...

Preparation of Nanocellulose Reinforced Chitosan Films, Cross-Linked by Adipic Acid

Adipic acid, an abundant and nontoxic compound, was used to dissolve and cross-link chitosan. After the preparation of chitosan films through casting technique, the in situ amidation reaction was performed at 80-100 °C as verified by Fourier transform infrared (FT-IR). The reaction was accompanied by the release of water which was employed to investigate the reaction kinetics. Accordingly, the ...

Rheological properties of cross-linked hyaluronic acid dermal fillers.

AIM Ha based dermal fillers in recent years aroused big interest in the area of cosmetic surgery for the rejuvenation of the dermis. There is not a ideal dermal filler (DF) for all applications and in commerce there are many types of DF that differ for their chemical-physical properties. So the aim of this paper is to correlate the rheological and physical properties of different DF to their cl...
