Microspheres of alginate-chitosan containing isoniazid
(Taylor & Francis Ltd, 2003-01-01)
Isoniazid was encapsulated into microspheres of alginate-chitosan by means of a complex coacervation method in an emulsion system. Since the encapsulation of isoniazid tends to be limited by its hydrophilic characteristics, ...
Interaction of amphiphilic derivatives of chitosan with DPPC (1,2-dipalmitoyl-sn-glycero-3-phosphocholine)
(Springer, 2010-04-01)
The interaction of chitosan and its N-dodecyl and poly(ethylene glycol) derivatives with 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) vesicles was studied to evaluate the influence of molecular architecture of the ...

Chitosan/Carbomer-based tablets containing Metronidazole for potential treatment of periodontal diseases
(2012)
Mucoadhesive tablets with different mixtures of chitosan and carbomer homopolymer type B were prepared in order to obtain new formulations containing metronidazole for periodontal disease treatment. All tablets were ...
Chitosan and oligo(DL-lactic acid) networks: Correlations between physical properties and macromolecular configuration
(Elsevier B.V., 2016-06-14)
Aiming the obtainment of materials with useful properties for bio-applications, as thermal and mechanical (in particular flexibility), chitosan and low molecular weight poly(lactic acid) were chosen due to their biodegradability ...
Overview of chitosan-based nanosystems for prostate cancer therapy
(2021-11-05)
Prostate cancer is considered a non-cutaneous cancer and has high prevalence and mortality rates worldwide. Chemotherapeutic agents have several side effects due to non-specific systemic biodistribution. Alternatively, ...
Obtention and characterization of collagen and chitosan based cements for bone regerneration. Part 1: extraction and characterization of collagen
(2014)
Several cements are used as biomaterials. Biopolymers such as chitosan and collagen exhibit excellent biocompatibility and can be used in the remodeling of bone tissue. The cement must have high mechanical strength and ...
Chitosan based films. synthesis and crystalline properties of nanocomposites with amine propyl siloxane
(1997)
The sol-gel treatment of equal amounts of chitosan and partially hydrolyzed aminopropylsiloxane (APS) leads to the formation of transparent, flexible films indicating high compatibility at the molecular level of the ...
Lithium ion conductivity of molecularly compatibilized chitosan–poly (aminopropyltriethoxysilane)–poly(ethylene oxide) nanocomposites
(Elsevier , Science Ltd., 2007-05-31)
Films of composites of chitosan/poly(aminopropyltriethoxysilane)/poly(ethylene oxide) (CHI/pAPS/PEO) containing a fixed amount of lithium
salt are studied. The ternary composition diagram of the composites, reporting ...
