Micro/nanostructured hyaluronic acid matrices with tuned swelling and drug release properties
(American Chemical Society, 2013-01)
Hyaluronic acid (HA) hydrogels were structured in the form of porous monoliths by means of the ice-segregation-induced self-assembly (ISISA) method coupled with freeze-drying. Physical and chemical parameters were explored ...
Films based on soy protein-agar blends for wound dressing: Effect of different biopolymer proportions on the drug release rate and the physical and antibacterial properties of the films
(SAGE Publications, 2018-04)
No single material can provide all requirements for wound dressings. Here, we evaluated the influence of different soy protein isolate and agar proportions (3:1, 1:1, and 1:3) in blend films on some of their physical-chemical ...
N,N-Dimethylacrylamide Hydrogels for Controlled Drug Delivery. Influence of Network Structure and Drug Solubility on the Load and Release Mechanisms
(Planta Piloto de Ingeniería Química, 2019-08)
The aim of the present work was to synthesize sustained-release hydrogels based on N,N-dimethylacrylamide (DMA) to study the effect of the polymer matrix structure and the solubility of drugs on the load and release ...
Evaluation of the Drug Release Kinetics in Assembled Modular Systems Based on the Dome Matrix Technology
(John Wiley & Sons Inc, 2020-06-10)
Mathematical models are an important tool in pharmaceutical formulationsdevelopment, to evaluate in vitro and in vivo drug release processes and to optimize the design of new systems. Dome Matrix technology allows the ...
Correlation between rheological propertiesm and limonene release in pectin gels using an electronic nose
(Elsevier, 2008-07)
Pectin gels at different polymer concentrations were used as matrices for the encapsulation of a volatile flavour (limonene). This provides a useful model system for studying the influence of the matrix viscoelastic ...
Chitin nanowhiskers as alternative antimicrobial controlled release carriers
(Royal Society of Chemistry, 2015-01)
Antimicrobial finishings protect users from pathogenic and odor-generating microorganisms, which are of medical and hygiene concerns. Controlled release is a useful approach to obtain antimicrobial finishings in several ...
Stability and release of an encapsulated solvent-free lycopene extract in alginate-based beads
(Elsevier Science, 2016-12)
A free-solvent lycopene extract was obtained from a natural and non-conventional source such as pink grapefruit. Five matrices were evaluated to select the matrix for lycopene extraction, choosing freeze-dried pulp based ...
Poly (vinyl alcohol) hydrogels: Influence of processing variables on general behavior and drug release device performance
(Nova Science Publishers, 2011)
Poly (vinyl alcohol) (PVA) hydrogels have a number of interesting properties whose make it an excellent candidate for several applications. One of the well known uses of these materials is like drug delivery device for ...
Flavor release by enzymatic hydrolysis of starch samples containing vanillin-amylose inclusion complexes
(Elsevier Science, 2014-05)
Hylon VII is a high amylose corn starch which has excellent gelling properties, and its behavior as flavor encapsulant is relevant to the food industry because its ability to regulate a swelling-controlled release in aqueous ...
Bioactive starch nanocomposite films with antioxidant activity and enhanced mechanical properties obtained by extrusion followed by thermo-compression
(Elsevier, 2019-11)
In this work bioactive starch films with antioxidant activity were developed by extrusion followed by thermo-compression. Rosemary extract was incorporated into starch-glycerol films in different concentrations (2.5%, 5% ...
