Abstract
Abstract Background The use of novel materials as an artificial extracellular matrix for stem cell growth is a current strategy of increasing interest for regenerative medicine. Here, we prepare thermal-remolded membrane scaffolds from poly(3-hydroxybutyrate) grafted with 2-amino-ethyl methacrylate hydrochloride. However, it is unclear whether these membranes are useful for tissue engineering. Results The mechanical properties, tribology, and morphology of the dense membranes were assessed. The results show that tensile strain at break and roughness of the compressed membrane decrease with increasing graft degree. Moreover, graft copolymer membranes showed lower resistance to scratching, greater degree of swelling and higher brittleness than un-grafted P(3HB) films. Thus, it effectively supports the growth of dermal fibroblast, as demonstrated by epifluorescence microscopy. Conclusions It is concluded that the developed membrane can be properly used in is the restoration of skin tissue. How to cite: Gonzalez-Torres M, Sanchez-Sanchez R, Solis-Rosales SG, et al.

Abstract A new type of cell-carrier-scaffold based on the surface modification of poly(3-hydroxybutyrate- co -3-hydroxyvalerate) by direct plasma-radiation-induced graft polymerization of N-hydroxyethyl-acrylamide was prepared. Parameters such as the membrane position for plasma treatment, delivering power and exposure time were varied. The yields over the film surfaces, chemical changes, morphology and roughness were surveyed. The results indicate that the tailoring is more favorable at 10 W fo...

The development of multi-species biofilms in chronic wounds is a serious health problem that primarily generates strong resistance mechanisms to antimicrobial therapy. The use of silver nanoparticles (AgNPs) as a broad-spectrum antimicrobial agent has been studied previously. However, their cytotoxic effects limit its use within the medical area. The purpose of this study was to evaluate the anti-biofilm capacity of chitosan gel formulations loaded with AgNPs, using silver sulfadiazine (SSD) as ...

Materials are often characterized in terms of their toughness, though more than one definition of toughness exists. Likely the most widely recognized means of defining material toughness, denoted here as τ, is by the area under the stress strain curve from a tensile test. Another important feature describing the nature of materials is that property known as brittleness, which has for a long time been much less quantitatively understood. Using a quantitative definition of brittleness provided in ...

Abstract The present study is aimed to investigate the degree of crystallinity of poly(3-hydroxybutyrate) P(3HB) grafted with poly(2-aminoethyl methacrylate hydrochloride) (PAEMA) chains using WAXS, micro Raman, and FTIR spectroscopy. The samples were obtained by radiation induced graft polymerization of the monomer in the substrate using different solvents for comparison. The results of crystallinity are consistent with those obtained of lower crystallinity in grafting copolymer relative to the...

Background: This study evaluated the biocompatibilities of random and putative block poly(3-hydroxybutyrateco-3-hydroxyvalerate)s (PHBVs) produced by a metabolic reaction-based system. The produced PHBVs were fractionated, and the copolymer sequence distributions were analyzed using 1 H and 13 C NMR spectroscopy. The thermal properties were analyzed using differential scanning calorimetry (DSC). Mechanical tests were conducted using a universal testing machine. The in vitro cytotoxicities of fil...

Abstract In the present study, 3D FT-IR spectroscopic imaging measurements were applied to study the phase separation of a poly(3-hydroxybutyrate) (PHB)/poly( l -lactic acid) (PLA) (50:50 wt.%) polymer blend film. While in 2D projection imaging the z -dependent information is overlapped, thereby complicating the analysis, FT-IR spectro-micro-tomography, obtained from computed tomographic back projection calculations, results in distinct 3D chemical images that provide detailed information of pha...

Many bacteria have been found to produce various polyhydroxyalkanoates (PHA) biopolyesters. In many cases, it is not easy to control the structures of PHA including homopolymers, random copolymers and block copolymers as well as ratios of monomers in the copolymers. It has become possible to engineer bacteria for controllable synthesis of PHA with the desirable structures by creating new PHA synthesis pathways. Remarkably, the weakening of β-oxidation cycle in Pseudomonas putida and Pseudomonas ...

Electrospinning coupled with electrospraying provides a straightforward and robust route toward promising electrospun biocomposite scaffolds for bone tissue engineering. In this comparative investigation, four types of poly(3-hydroxybutyrate) (PHB)-based nanofibrous scaffolds were produced by electrospinning a PHB solution, a PHB/gelatin (GEL) mixture or a PHB/GEL/nHAs (hydroxyapatite nanoparticles) mixed solution, and by electrospinning a PHB/GEL solution and electrospraying a nHA dispersion si...

Abstract Tendon injuries and defects present a substantial burden to global healthcare economies. There are no synthetic/biosynthesised implants available which can restore full function or match the mechanical properties of native tendon. Therefore, poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) was investigated for its utility as a scaffold in a rat Achilles tendon repair model. Porous PHBHHx tubes and fibres were prepared with particle leaching and extrusion methods, respectively. Col...

Abstract Using plasma-initiated polymerization, poly(acrylic acid) (PAA) was grafted onto the film surfaces of polyhydroxyalkanoate (PHA), poly[( R )-3-hydroxybutyrate] (P(3HB)), and two kinds of poly[( R )-3-hydroxybutyrate- co -4-hydroxybutyrate] (P(3HB- co -4HB)) with 4.7 mol% or 9.4 mol% of 4HB content. The graft ratio of PAA on the film surface increased drastically with acrylic acid concentration over 8%. Attenuated total reflection Fourier transform infrared spectroscopy demonstrated that...

Abstract A novel brush-like poly(2-aminoethyl methacrylate) (PAEMA) was grafted onto chitosan (CS) through gamma radiation-induced polymerization. The copolymer (CS-g-PAEMA) was used to prepare a sodium acetate leached poly(urethane-urea) scaffold. The above derivatives were developed, synthesized, and characterized to meet the specific characteristics of biomaterials. The results revealed that this method is an easy and successful route for grafting PAEMA onto CS. The feasibility of preparing a...

Abstract Poly(hydroxybutyrate) (PHB) has been considered as a promising biopolymer produced in certain microbes under specific fermentative and physiological conditions. Being less functional, hydrophobic and brittle, the processability of PHB is difficult which limits its widespread applications. However, its blends with suitable biopolymers, for instance biopolyesters, may impart in them desirable structural functionalities and properties, such as surface reactivity, amphiphilicity, controlled...

Abstract Both chitosan (CS) and poly(3-hydroxybutyrate) (P(3HB)) are two good options for use in tissue engineering. Some of the advantages of these polymers are biodegradability and non-toxicity. However, the inadequate mechanical properties and hydrophobicity (P3HB) and the low porosity (CS) are examples of shortcomings that restrict its applications. The polysaccharide was grafted onto P(3HB) in a previous work for removing these disadvantages. As of yet, it is still unknown whether our P(3HB...

Abstract In this work, a green composite from poly(3-hydroxybutyrate), or P(3HB), grafted with 2-amino-ethyl methacrylate, hydroxylated resin and silica nanoparticles was developed. The goal was to determine if the new poly(urethane-urea) composite can work as an appropriate substrate for biological applications. The mechanism for the polyurea step-growth polymerization was proposed. The scaffolds showed an average porosity and degree of swelling of 55% and 7%, respectively, as well as a reinfor...

Abstract The combination of spectroscopy studies with simulation models can be a useful tool to predict the applications of macromolecules. However, it is currently unknown if applications of polyhydroxyalkanoate (PHA) derivatives can be determined with this methodology. Here, we used a new nuclear magnetic resonance (NMR) technique to structurally characterize poly (3-hydroxybutyrate) grafted with 2-aminoethyl methacrylate and combined the experimental results with those of molecular dynamic si...
