This study aims to provide an overview of the latest research studies on use biopolymers in various textile processes, from spinning processes dyeing and finishing treatment, proposed as a possible solution reduce environmental impact industry. Recently, awareness polluting aspects production, based petroleum derivatives, has grown significantly. Environmental issues resulting greenhouse gas emissions, waste accumulation nature landfills, have pushed activities toward more sustainable, low-impact alternatives. Polymers derived renewable resources and/or with biodegradable characteristics were investigated follows: (i) constituent materials yarn view their superior ability be decomposed compared common synthetic petroleum-derived plastics, positive antibacterial activities, good breathability, mechanical properties; (ii) act biological catalysts; (iii) impart specific functional properties treated textiles; (iv) 3D printing technologies fabric surfaces replace traditionally pollutive dye-based inkjet printing; (v) implants for treatment dye-contaminated water.

Abstract A dressing patch made of radially oriented poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nanofibers was successfully manufactured with a modified electrospinning strategy. The as-electrospun PHBV nanofiber exhibited uniform and bead-free nanofibrous morphology innovative arrangement, which demonstrated to possess obviously improved mechanical property, increased surface hydrophilicity enhanced biological properties compared the control traditionally randomly pattern. Interestingly, it found that pattern could induce cell migration from periphery center along in rapid manner. To further improve biofunction patch, berberine (Beri, an isoquinoline alkaloid) two different concentrations were encapsulated into during electrospinning, present sustained drug release behavior for nearly one month. Importantly, addition Beri impart excellent anti-inflammatory property by significantly inhibiting secretion pro-inflammatory factors M1 macrophages, also showed additive influence on promoting proliferation human dermal fibroblasts (HDFs), as well growth E. coli, S. aureus C. albicans, Beri-free patch. In animal studies, electrospun loading high content accelerate healing process diabetic mouse full-thickness skin wound shortened time (100% closure rate after 18 days’ treatment) quality (improved collagen deposition, re-epithelialization neovascularization hair follicles). all, this study reported therapeutic strategy integrating physical cues multiple effective treatment hard-to-heal wounds.

Polyhydroxyalkanoates (PHAs) are high-value biodegradable polyesters with thermoplastic properties used in the manufacturing of different products such as packaging films. PHAs have gained much attention from researchers and industry because their biobased nature appropriate features, similar to conventional synthetic plastics. This review aims discuss some recent solutions challenges associated PHA production. The implementation a cost-effective process is presented by following strategies, use inexpensive carbon sources, selection high-producing microorganisms, functionalization final materials make them suitable for food applications, among others. Research efforts needed improve economic viability production at large scale. Haloferax mediterranei promising producer due its ability grow non-sterile conditions possibility using seawater prepare growth medium.

Herbal drugs are safe and show significantly fewer side effects than their synthetic counterparts. Curcumin (an active ingredient primarily found in turmeric) shows therapeutic properties, but its commercial use as a medication is unrealized, because of doubts about potency. The literature reveals that electrospun nanofibers simplicity, efficiency, cost, reproducibility compared to other fabricating techniques. Forcespinning new technique minimizes limitations provides additional advantages electrospinning. Polymer-based nanofibers-whose lie stability, solubility, drug storage-overcome problems related delivery, like instability hydrophobicity. Curcumin-loaded polymer potency healing diabetic wounds vitro vivo. release profiles, cell viability, proliferation assays substantiate efficacy bone tissue repair delivery against lung, breast, colorectal, squamous, glioma, endometrial cancer cells. This review mainly discusses how interact with curcumin medical efficacy.

Tissue engineering technology aids in the regeneration of new tissue to replace damaged or wounded tissue. Three-dimensional biodegradable and porous scaffolds are often utilized this area mimic structure function extracellular matrix. Scaffold material design significant areas biomaterial research most favorable for seeding vitro vivo cells. Polyhydroxyalkanoates (PHAs) biopolyesters (thermoplastic) that appropriate application due their biodegradability, thermo-processability, enhanced biocompatibility, mechanical properties, non-toxicity, environmental origin. Additionally, they offer enormous potential modification through biological, chemical physical alteration, including blending with various other materials. PHAs produced by bacterial fermentation under nutrient-limiting circumstances have been reported perspectives devices biological applications. The present review discusses applications conventional medical devices, especially soft (sutures, wound dressings, cardiac patches blood vessels) hard (bone cartilage scaffolds) paper also addresses a recent advance highlighting usage implantable such as heart valves, stents, nerve guidance conduits nanoparticles, drug delivery. This summarizes biodegradability conducts an overview current scientific achievements development biomedical sector. In future, may synthetic plastics choice researchers practitioners.

Polyhydroxyalkanoates (PHAs) are natural polymers produced under specific conditions by certain organisms, primarily bacteria, as a source of energy. These up-and-coming bioplastics an undeniable asset in enhancing the effectiveness drug delivery systems, which demand characteristics like non-immunogenicity, sustained and controlled release, targeted delivery, well high loading capacity. Given their biocompatibility, biodegradability, modifiability, compatibility with hydrophobic drugs, PHAs often provide superior alternative to free therapy or treatments using other polymeric nanocarriers. The many formulation methods existing PHA nanocarriers, such emulsion solvent evaporation, nanoprecipitation, dialysis, situ polymerization, explained this review. Due flexibility that allows for vessel tailormade its intended application, nanocarriers have found place diverse options anticancer anti-infective treatments, among applications discussed article. Despite positive attributes, advancement clinical trials has been stunted due polymers’ hydrophobicity, controversial production materials, costs, others. challenges explored review, alongside solutions alternatives.

In this work, the potential of a synthetic coculture and mixed methanotrophic consortium to synthesize poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) from renewable waste-based feedstocks was assessed batchwise. Methylocystis parvuscocultivated with Rhodococcus opacus Methylocystis-enriched culture previously grown on methane were subjected nutrient starvation in medium enriched valeric acid (30% w w–1 Ctot) or VFAs mixture containing acetic, propionic, butyric, acids (15% under CH4:O2 air atmosphere. For all test series, pH adjusted 7 after adding cosubstrates, negligible substrate consumption polymer production considered end point trial. Results showed that promoted PHBV accumulation both cultures regardless Interestingly, supported only presence methane. The highest contents for consortium, equal 73.7 ± 2.5% 49.6 13% w–1, respectively, obtained mixture. This study demonstrates suitability cocultures biobased cosubstrates sustainable biodegradable PHBV.
