Tragacanth gum-based hydrogels for drug delivery and tissue engineering applications

Frontiers in Materials, Journal Year: 2024, Volume and Issue: 11

Published: Feb. 16, 2024

Natural polymers have many uses, and Tragacanth gum is just one of them. Many people are interested in natural gums because their attractive characteristics, such as being ‘green’ bio-based renewable materials, easily accessible, inexpensive, structurally diverse. One class naturally occurring polysaccharides called its tendency to create a gel or thick solution. Among the plant-based raw these polysaccharide abundant. Hydrogels, which three-dimensional polymeric webs that can imitate live tissues, demonstrated remarkable potential adjustable biomaterials numerous regenerative techniques due high water biological exudate absorption capacities. polysaccharides, often known gums, present different types trees possess desirable properties, renewable, biocompatible, biodegradable, non-toxic, amenable chemical modification. curious about certain parts food, water, energy, biotech, environmental, healthcare sectors now. Gum, type very important unique food ingredient, has vital uses business. Cosmetics, coating, photosensitive resin, fertilizer, casting, pharmaceuticals, tobacco few non-food businesses make use strong water-affinity structural plasticity. There lot benefits hydrogels made from opposed those synthetic sources. Synthesis hydrogel been center interest among applications extensive pharmaceutical medical fields. The used for medication delivery tissue engineering focus this study. We also paid close attention drug delivery, physical-chemical extraction gum. Our research wide range biomedical applications, including bone, skin, fixation periodontal, cartilage. Possible futures based on were likewise our primary focus.

Properties and Characterization Techniques of Graphene Modified Asphalt Binders

Nanomaterials, Journal Year: 2023, Volume and Issue: 13(5), P. 955 - 955

Published: March 6, 2023

Graphene is a carbon-based nanomaterial used in various industries to improve the performance of hundreds materials. For instance, graphene-like materials have been employed as asphalt binder modifying agents pavement engineering. In literature, it has reported that (in comparison an unmodified binder) Modified Asphalt Binders (GMABs) exhibit enhanced grade, lower thermal susceptibility, higher fatigue life, and decreased accumulation permanent deformations. Nonetheless, although GMABs stand out significantly from traditional alternatives, there still no consensus on their behavior regarding chemical, rheological, microstructural, morphological, thermogravimetric, surface topography properties. Therefore, this research conducted literature review properties advanced characterization techniques GMABs. Thus, laboratory protocols covered by manuscript are atomic force microscopy, differential scanning calorimetry, dynamic shear rheometer, elemental analysis, Fourier transform infrared spectroscopy, Raman electron thermogravimetric X-ray diffraction, photoelectron spectroscopy. Consequently, main contribution investigation state-of-the-art identification prominent trends gaps current state knowledge.

Measuring Physical Properties of Electrospun Nanofiber Mats for Different Biomedical Applications

Membranes, Journal Year: 2023, Volume and Issue: 13(5), P. 488 - 488

Published: April 30, 2023

Electrospun nanofiber mats are nowadays often used for biotechnological and biomedical applications, such as wound healing or tissue engineering. While most studies concentrate on their chemical biochemical properties, the physical properties measured without long explanations regarding chosen methods. Here, we give an overview of typical measurements topological features porosity, pore size, fiber diameter orientation, hydrophobic/hydrophilic water uptake, mechanical electrical well vapor air permeability. Besides describing typically methods with potential modifications, suggest some low-cost alternatives in cases where special equipment is not available.

Superabsorbent polymers in soil: The new microplastics?

Cambridge Prisms Plastics, Journal Year: 2024, Volume and Issue: 2

Published: Jan. 1, 2024

Abstract The extensive use of synthetic polymers in our everyday lives has resulted significant plastic pollution. Superabsorbent (SAPs) are yet another class anthropogenic materials with uncertain environmental implications. SAPs, like polyacrylates (PAA) or polyacrylamides (PAM), find applications personal care products, construction, wastewater treatment, agriculture and soil remediation. However, when SAPs enter the soil, weathering may change their intended properties, potentially forming plastic-like solid residues over time. This review aims to evaluate current scientific understanding application fate focusing on processes driving potential transformation into residues. We explore analytical techniques for qualitative quantitative characterization SAP Our research provides first insights mechanisms conditions governing aging transformation, advancing impact properties functioning. There specific knowledge gaps regarding influence climate soil. To facilitate future research, we suggest scrutinizing relevant field, critically (re)evaluating establishing robust monitoring methods.
