Synthesis of a semi-interpenetrating polymer network as a bioactive curcumin film

Smart edible films based on mucilage of lallemantia iberica seed incorporated with curcumin for freshness monitoring

The objective of the present work was first to develop a smart packaging system based on Lallemantia iberica seed gum (LISG)/curcumin and, subsequently, investigate its physicochemical characteristics and biological activity. Finally, the response of LISG/curcumin films against pH change and the spoilage of shrimp were tested. The barrier properties and mechanical performance of the films improved as the curcumin concentration increased. FT-IR analysis revealed the formation of physical interaction between LISG and curcumin. LISG/curcumin films showed a continuous and steady release of curcumin. The incorporation of curcumin into LISG matrix imparts antioxidant and antibacterial/mold activity to the films. A strong positive correlation was observed between total volatile base nitrogen (TVBN) content of shrimp and a* (redness) during storage time (Pearson correlation = 0.975). Eventually, LISG/curcumin film could be a promising smart packaging system capable of detecting food spoilage.

Drug/Vehicle Impacts and Formulation Centered Stratagems for Enhanced Transdermal Drug Permeation, Controlled Release and Safety: Unparalleled Past and Recent Innovations-An Overview

:

Transdermal drug delivery systems (TDDS) are one of the fascinating unconventional drug delivery systems offering plentiful advantages of which patient compliance is of paramount importance. However, as a matter of fact, the transdermal delivery of drug molecules is absolutely a tedious job which is precisely influenced by a number of factors including penetration barrier properties of the skin, drug characteristics formulation allied issues, etc. Over the years, innumerable tremendous efforts have been made in transporting the drugs through the skin into the systemic circulation by noteworthy tactics. This paper discusses such revolutionary formulation based techniques that have been endeavored in achieving the enhanced skin permeation of drugs, controlled release, and safety.

Development a smart edible nanocomposite based on mucilage of Melissa officinalis seed/montmorillonite (MMT)/curcumin

The aim of the present study was, first to fabricate Melissa officinalis seed gum (MOSG)-based films incorporated with montmorillonite (MMT) at various concentrations and subsequently, evaluate of the physicochemical properties of the developed films. Afterward, the anti-bacterial and anti-mold activities of the developed nanocomposites were assessed. Finally, curcumin was incorporated into formulation of the fabricated film at optimal condition to sense pH changes. Incorporating MMT nanoparticles into MOSG-based films could reduce the thickness, water solubility and moisture content of the samples. Tensile strength (TS) and elongation at break (EB) values significantly increased with increase of MMT concentration. The nanoparticle addition specifically at higher levels resulted in increase of agglomeration. Neither anti-mold and nor anti-microbial activity were observed for the tested nanocomposites. The films containing curcumin had good antibacterial and anti-mold activities and can be used as smart package due to their ability to sense the pH change.

Biomedical Applications of Interpenetrating Polymer Network System

Interpenetrating polymer network (IPN) has been regarded as one of the novel technology in recent years showing the superior performances over the conventional techniques. This system is designed for the delivery of drugs at a predetermined rate and thus helps in controlled drug delivery. Due to its enhanced biological and physical characteristics like biodegradability, biocompatibility, solubility, specificity and stability, IPN has emerged out to be one of the excellent technologies in pharmaceutical industries. This article focuses mainly on the biomedical applications of IPN along with its future applicability in pharmaceutical research. It summarizes various aspects of IPN, biomedical applications and also in-cludes the different dosage forms based on IPN.
