Abstract
Bio-based materials are rapidly replacing synthetic materials owing to their significant biomedical applications, easy availability, nontoxicity, biodegradability and biocompatibility. Guar gum (GG) is a plant-derived biocompatible and biodegradable polymeric compound found abundantly in nature. It is a non-ionic, hydrophilic carbohydrate and is a cost-effective hydrocolloid polysaccharide considered as a wonderful representative of the new generation of plant gums. Various composites of guar gum with other polymers have been reported in last few decades and they are extensively used in different industries like food, textile, mining, petrochemical, paper and explosives etc. Easy availability, non-toxicity, eco-friendly and biodegradable nature of GG has made it ideal candidate for for drug delivery (DD) applications. GG based hydrogels, films, scaffolds and nanoparticles have been explored widely for their DD applications. These non-toxic DD carriers can be used for targeted drug delivery. This review article directs the current efforts and improvements on GG and GG-based materials to be used in DD.

Encapsulation with Natural Polymers to Improve the Properties of Biostimulants in Agriculture. PLANTS (BASEL, SWITZERLAND) 2022; 12:plants12010055. [PMID: 36616183 PMCID: PMC9823467 DOI: 10.3390/plants12010055] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 12/14/2022] [Accepted: 12/19/2022] [Indexed: 05/28/2023]
Abstract
Encapsulation in agriculture today is practically focused on agrochemicals such as pesticides, herbicides, fungicides, or fertilizers to enhance the protective or nutritive aspects of the entrapped active ingredients. However, one of the most promising and environmentally friendly technologies, biostimulants, is hardly explored in this field. Encapsulation of biostimulants could indeed be an excellent means of counteracting the problems posed by their nature: they are easily biodegradable, and most of them run off through the soil, losing most of the compounds, thus becoming inaccessible to plants. In this respect, encapsulation seems to be a practical and profitable way to increase the stability and durability of biostimulants under field conditions. This review paper aims to provide researchers working on plant biostimulants with a quick overview of how to get started with encapsulation. Here we describe different techniques and offer protocols and suggestions for introduction to polymer science to improve the properties of biostimulants for future agricultural applications.

Guar Gum-Based Floating Microspheres of Repaglinide Using 3 2 Factorial Design: Fabrication, Optimization, Characterization, and In Vivo Buoyancy Behavior in Albino Rats. Assay Drug Dev Technol 2020; 19:63-74. [PMID: 33090876 DOI: 10.1089/adt.2020.1006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/12/2022] Open
Abstract
In this present study, floating microspheres of repaglinide were successfully fabricated by the solvent evaporation technique with varying ratios of guar gum, hydroxypropyl methylcellulose, and ethylcellulose with polyvinyl alcohol. Microspheres were characterized by production yield, particle size, in vitro buoyancy, entrapment efficiency, in vitro drug release, and in vivo floating behavior in albino rats. The formulation process was optimized for stirring speed (X1) and concentration of polymer ratio (X2) on dependent variables such as percentage entrapment efficiency, percentage yield, in vitro buoyancy, and percentage of drug release by the 32 factorial Design-Expert® 12, trial version, software. The optimized formulation was characterized by Fourier transform infrared spectroscopy, powder X-ray diffraction, differential scanning calorimetry, and scanning electron microscopy and was successfully formulated with the highest percentage of cumulative drug release (94.26 ± 3.10), entrapment efficiency (74.70% ± 2.16%), and particle size (50.34 ± 3.67 μm) and remains buoyant for 24 h in simulated gastric fluid (0.1N HCL) with high in vitro buoyancy percent (84.90 ± 2.88). When the drug-polymer solution of dichloromethane and ethanol is dropped in polyvinyl alcohol solution, it leads to the formation of a shell and produces cavities, creating the buoyant nature of floating microspheres. X-ray imaging indicates the uniform distribution and buoyant nature of microspheres in the gastric fluid for a 10-h period.

Abstract
A series of chitosan/poly(vinyl alcohol)/guar gum (CS/PVA/GG) blends were prepared. The synthesis was carried out using different combinations of CS and GG, while keeping PVA constant by casting solution method. The effect of formaldehyde as a crosslinking agent was also evaluated. The blends were characterized by scanning electron microscopy (SEM), Fourier Transform Infra-red (FTIR) and X-ray powder diffraction (XRD). Additionally, the swelling ratio along with antimicrobial activity was also studied. SEM exhibited the phenomenon that surface morphology was mostly affected by blend ratios and cross-linker. The XRD shows the crystalline structure of blends. The FTIR confirmed the strong intermolecular bonding between polymers. Swelling exhibits that cross-linking affects the hydrophilicity of blends and swelling was excellent for S4 blend. The prepared blends showed promising antimicrobial activity against P. multocida, S. aureus, E. coli, and B. subtilis bacterial agents. The data concludes that GG, CS and PVA ternary blends could possibly be used for the biomedical applications.
