ABSTRACT This study was carried out to determine the effects of coating with chitosan film and storing at different periods (7, 14, and 21 days) of broiler breeder eggs on growth performance and carcass characteristics o...

The design of novel delivery systems to treat vaginal fungalinfections is a topic of high interest. Chitosan, being itselfantimicrobial and having good mucoadhesive properties, is an excellentcandidate as a delivery matr...

ABSTRACT The significant growth of the industrial sector in recent decades has led to an increase in the volume of waste, which if not properly destined, could cause serious environmental problems. In the context of aqua...

Bone plays a vital role in providing the structural framework of the human body and protecting internal organs. Porous scaffolds that promote cell proliferation is necessary to artificially create bone by tissue engineer...

Electrospinning is a technique that allows the preparation of nanofibers from various materials. Chitosan is a natural and abundant easily obtained polymer, which, in addition to those features, proved to be biocompatibl...

Abstract Polymer molecular weight plays a central role in determining the balance between electrostatic and steric stabilization in polymer-coated colloidal systems, yet its influence on nanoparticle accessibility at sof...

Soybean hull peroxidase (EC 1.11.1.7, SBP) was simultaneously purified and immobilized by dye affinity chromatography with Reactive Blue 4 attached to chitosan mini-spheres. Under optimized conditions, 96% of SBP was ads...

To investigate the effects of magnetic stimulation mediated by magnetic/graphene (MNP/G) composite nanomaterials on human scleral fibroblast (HFSF) proliferation and collagen synthesis, exploring its potential for myopia...

In the present study, we sought to systemically evaluate the biodistribution and the tumor-accumulation of N-succinyl-chitosan nanoparticles (Suc-Chi-NPs, 200 nm in diameter) in model tumor-bearing mice and also the bind...

Chitosan is increasingly used as an alternative to synthetic polymers due to its water solubility, biodegradability, and biological activity. In this work, chitosan samples from three suppliers were evaluated and charact...

The present study involves the preparation of nimesulide-chitosan microparticles (NCM) as sustained delivery carriers with different polymer concentrations by pH change coacervation method using glutaraldehyde as cross-l...

The aim of this study was to develop sustained release formulation for improving bioavailability of metronidazole designing metronidazole loaded chitosan microcapsules (MLCM) using coacervation technique. Two solutions w...

Didanosine (ddI) is an important drug in the AIDS therapy. However, to overcome the instability of ddI in acid medium, the tablets have a large amount of buffer that can lead to side effects such as diarrhea and kidney p...

Polymeric membranes have been used as wound dressings for burns and healing wounds. Healing properties, anti-inflammatory and antibiotic in such membranes can be induced and/or made possible with the incorporation of bio...

The purpose of the present investigation is to study the effect of incorporation of gelucire 39/01 and 50/13 on encapsulation efficiency and release of water soluble drug (metronidazole, log P = 0.0) from floating gellan...

The purpose of this study was to investigate the impregnation of chitosan microspheres with the natural dye curcuma. The impregnation with curcuma dye was investigated in aqueous medium at pH 9.0, 9.5 and 10.0. The proce...

The objective of the present investigation was to evaluate the potential of gellan gum- low molecular weight chitosan (GG-LMCH) polyelectrolyte complex (PEC) in the form of beads as prolonged release stomach specific flo...

The purpose of the present investigation was to prepare gellan-chitosan polyelectrolyte complex beads in one step and to explore the potential of the prepared beads in the oral delivery of metronidazole (log P = 0.0) and...

A novel polymer, chemically modified chitosan was synthesized by reacting with hydrochloride salt of 2-aminoethanoyl chloride. Formation of novel chemically modified chitosan was confirmed by FTIR and NMR spectroscopy an...
