Light-emitting gel, a gel state electroluminescence material, is reported. It is composed of a ruthenium complex as the emitter, an ionic liquid as the electrolyte, and oxide nanoparticles as the gelation filler. Emitted light was produced via electrogenerated chemiluminescence. The light-emitting gel operated at low voltage when an alternating current was passed through it, regardless of its s...

The aim of this study was to apply the external ionic gelation using an atomizing spray device comprised of a spray gun to improve the viability of Lactobacillus plantarum DKL 109 and for its commercial use. Three coating material formulas were used to microencapsulate L. plantarum DKL 109: 2% alginate (Al), 1% alginate/1% gellan gum (Al-GG), and 1.5% alginate/3% gum arabic (Al-GA). Particle si...

ISSN:0975-1459 The development of alginate beads as a drug carrier system is considered to be more attractive because of its biocompatibility, mucoadhesive property, and its ability to deliver drug particularly in the intestinal pH. The preparation of alginate beads by ionic gelation method avoids the usage of toxic organic solvents and considered to be relatively economical method. However its...

The development of oral sustained or controlled release dosage form of captopril has been an interested topic of research for a long period of time. Difficulties encountered on the fact that the drug is freely water soluble. Such drug is difficult to be delivered orally in a sustained or controlled release manner and, Due to its effectiveness and intensive use as a drug of choice in the treatme...

Introduction: Hyaluronic acid (HA) is an anionic biopolymer composed of alternating disaccharide units of D-glucuronic acid and Nacetyl-D-glucosamine with (14)interglycosidic linkage [1]. It is the only nonsulfated glycosaminoglycan (GAG) that is abundant in the synovial fluid and extracellular matrix (ECM) [1-2]. The over all goal of this study is to fabricate and characterize nanospheres ba...

A facile strategy is reported to convert sugarcane bagasse (SCB) cellulose into phosphorylated nanofibrils (PCNFs) whose gelation pH-dependent via the different ionic forms of phosphoric groups (H2PO4?, HPO4?2, PO4?3). Cellulose was isolated from SCB at a 42.1% yield, then an optimized 1:0.5:2 anhydroglucose (AHG)/(NH4)2HPO4/CO(NH2)2 molar ratio and, pH 12, in most charged phosphate (PO4?3) be ...

The reaction pathway during the formation of silica via a two-component "non-aqueou" sol-gel synthesis is studied by in situ time-resolved Raman spectroscopy. This synthetic route is followed with and without the addition of the protic ionic liquid 1-ethylimidazolium bis(trifluoromethanesulfonyl)imide (C2HImTFSI) in order to investigate its effect on the reaction pathway. We demonstrate that Ra...

In recent years, there have been major advances and increasing amounts of research on the utilization of natural polymeric materials as drug delivery vehicles due to their biocompatibility and biodegradability. Seaweed polysaccharides are abundant resources and have been extensively studied for several biological, biomedical, and functional food applications. The exploration of seaweed polysacc...
