Controlling the self-assembly of diphenylalanine peptide (FF) into various nanoarchitectures has received great amounts of attention in recent years. Here, we report the temperature-induced reversible self-assembly of diphenylalanine peptide to microtubes, nanowires, or organogel in different solvents. We also find that the organogel in isopropanol transforms into crystalline flakes or nanowire...

The droplet interface bilayer (DIB) is a promising technique for assembling lipid membrane-based materials and devices using water droplets in oil, but it has largely been limited to laboratory environments due to its liquid construction. With a vision to transform this lab-based technique into a more-durable embodiment, we investigate the use of a polymer-based organogel to encapsulate DIBs wi...

The new sugar-based gelators 1 and 2 were synthesized, and their gelation abilities were evaluated in organic solvents and in water. Compound 1 gelates both water and organic solvents whereas 2 gelates only organic solvents. Superstructural difference between hydrogel 1 and organogel 2 was investigated by CD, TEM, AFM, 1H NMR and XRD. Hydrogel 1 displays a well-developed helical ribbon structur...

An attempt is made in this study to balance the nutritional and sensory quality of bread. In particular, the formulation of a functional durum wheat bread enriched with bran at high concentration has been developed. Organogel concentration and bran particle size have been used as process variables for bread optimization. Bran concentration was increased at value as high as 15%, thus increasing ...

Organogel is a viscoelastic carrier system, can be regarded as a semi-solid preparation which has an immobilized external organic (apolar) phase. Organogels have evolved as one of the potential carrier system for topical delivery. When compared to other lipid based carrier systems, these prove to be better in terms of efficacy, feasibility and shelf life. Organogelator such as n-alkanes, fatty ...

The purpose of this study was to evaluate the in vitro release and ex vivo penetration of baclofen following incorporation into a 2% poloxamer lecithin organogel. Franz cells were utilized for both the release and penetration studies. Semi-permeable dialysis membranes were used as the model skin for the penetration study. Baclofen release and penetration at predetermined time points were assess...

An in vitro human percutaneous absorption study was conducted to assess the delivery of ketoprofen and testosterone from two base formulations, a Pluronic lecithin organogel and Pentravan Cream. Each formulation was applied to ex vivo human trunk skin (from three skin donors) on triplicate sections mounted onto Franz Diffusion Cells. Following a 5-mcL/cm2 applied dose, serial dermal receptor so...

A simple working definition of this term'Gel' is a soft, durable or solid material,containing both solids and liquid parts, where the part(gelator) exists as amesh / network aggregates, viz immobilize part liquid,a strong prevents from leaking flow, especially by local pressure. The gel called hydrogel Organogel depending on type component: water in living solvent organogels .Organogels have be...

Electrolytes are characterized by their ionic conductivity (σ(i)). It is desirable that overall σ(i) results from the dominant contribution of the ions of interest (e.g. Li(+) in lithium ion batteries or LIB). However, high values of cationic transference number (t+) achieved by solid or gel electrolytes have resulted in low σ(i) leading to inferior cell performances. Here we present an organog...

Objective: Treatment of mood and behavioral symptoms in geriatric patients with advanced dementia may be impeded by poor compliance with oral medications. Pluronic lecithin organogel (PLO) is a compounding substrate that can be used for the topical administration of psychotropic medications. Methods: Charts of patients treated with psychotropic medications compounded with PLO cream were reviewe...
