sciforum-032169 | Characterization of Electrochemical Sensors Based on Carbon Nanotubes and MIPs for Determination of Ferulic Acid | , , | N/A | N/A |
Show Abstract |
||||||||||||||||||||||||||||||||||||
In order to mitigate the impacts caused by the rampant consumption of fossil fuels, many countries are investing in the development and optimization of alternatives that minimize dependence on fossil energy. The production of first generation ethanol (1G) appears as an attractive option, but it competes with the food chain, generating the need to find other sources of energy. The second generation of ethanol (2G), characterized by its relevant production potential, is considered a good alternative, which can be produced from sugarcane bagasse. Therefore, it is extremely important to evaluate the efficiency of 2G ethanol production processes, mainly in the compositional analysis of hydrolysates from the pre-treatment of lignocellulosic biomass, to promote greater production. Thus, the development of electrochemical sensors composed of graphite/paraffin composite electrodes coated with multi-walled carbon nanotubes (MWCNTs) modified with molecularly printed polymers (MIPs) are an excellent option for carrying out rapid analyzes. Due to the highly sensitive electrical properties of the MWCNTs and the molecular impression of the polymers that allow a high affinity with the model molecule, the sensor has high selectivity, good sensitivity and reproducibility for the determination of ferulic acid. For this reason, the present work presents a morphological study using the Scanning Electron Microscopy (SEM) technique and electrochemistry using the Cyclic Voltammetry (CV) technique. |

Show Abstract |
||||||||||||||||||||||||||||||||||||
Chronic wounds (CW) have numerous entry ways for pathogen invasion and prosperity, which further damages host tissue and hinders tissue remodeling. Essential oils (EOs) exert quick and efficient antimicrobial (AM) action, unlikely to induce bacterial resistance. Cinnamon leaf oil (CLO) is a well-studied EO with strong AM properties. In this work, CLO was added to chitosan (Ch) and polyvinyl alcohol (PVA) solutions. Ch is a natural cationic polysaccharide with antibacterial, anti-inflammatory and regenerative properties. PVA adds flexibility and hydrophilicity to the blend. Ch (100-300 KDa and 9.7±0.6% of DA) and PVA (72 KDa, 88% hydrolysed) films were prepared by solvent casting and phase inversion method (as previously done by the lab). CLO-enriched films included CLO added to Ch shortly before blending, and were based on its minimum inhibitory concentration (MIC; 19.7 µg/mL for S. aureus and 26.2 µg/mL for E. coli). Films chemical composition, thermogravimetric analysis, differential scanning calorimetry, and water absorption capability were tested. Films were successfully built. AM activity, via halo and shake flask tests, was particularly increased with CLO. This study is a first proof of concept that CLO can be dispersed into Ch and PVA films and show bactericidal effects, opening new perspectives for CW therapeutics. |

Wound care is a growing industry that lately has been facing multiple challenges due to the increasing health care costs, aging of population, appearance of antibiotic-resistant pathogens, and rise in the incidence of chronic diseases. Unlike acute wounds which heal in a predictable amount of time following the stages of healing, chronic wounds (CW) often fail to progress past the inflammatory phase, increasing costs and healing time. Bioactive dressings that incorporate drugs/antibiotics or bioactive molecules in their formulation have been suggested as alternatives to the conventional gauzes and foams. Here, we propose the combination of poly(vinyl alcohol) (PVA) and cellulose acetate (CA), both biodegradable and biocompatible polymers, for the production of films processed via a new method that combines principles from solvent casting and phase inversion, and modified with the antimicrobial peptide (AMP) LL37, as a new active solution. To guarantee some degree of flexibility, films were produced with a higher percentage of PVA compared to CA, from 90/10 to 50/50. LL37 was then anchored using dopamine as a binding agent. Films were characterized in terms of functional groups, thermal stability, tensile strength, porosity, swelling and degradation rate. The antimicrobial performance of LL37 surface-modified films was tested against Staphylococcus aureus, Staphylococcus epidermidis and Escherichia coli in dynamic environment. LL37-modified films demonstrated great antibacterial efficacy against the three bacteria, ≈ 75% inhibition for S. aureus, ≈ 85% for S. epidermidis and ≈ 60% for E. coli, regardless of PVA/CA ratio. Films treated with LL37 accelerated clotting time (≈ 10 min) above vancomycin and bare surfaces, demonstrating great capacity to activate the intrinsic coagulation cascade. In the end, the potential of LL37 functionalized PVA/CA films for prospective wound-healing applications was demonstrated. |

Show Abstract |

In the laser surface remelting (LSR) treatment, only a small region is heat affected, surpassing the melting temperature, and followed by a rapid cooling at 105 – 108 K/s, producing an extremely refined microstructure. The laser treated region shows a more homogeneous microstructure and better mechanical properties than the substrate. The LSR is a great technique to improve the Al alloys properties, increasing the hardness and wear resistance without modifying the composition of the material. Iron is commonly found as an impurity in Al-based alloys, but in the 2618 commercial alloy, around 1wt.% of Fe is intentionally added to improve the high temperature strength and the corrosion resistance. In addition, Al-Fe based alloys are used in packaging, architectural sheets and high voltage cables. In this work, LSR experiments were performed, with a CO2 laser operating in a continuous-wave mode, to investigate the influence of process parameters on the treated surface of an as-cast Al-1wt.%Fe alloy. These parameters cover work distance (z = 6 and 8 mm), laser beam speed (v = 500, 750 and 1000 mm/s) and laser average power (P = 400, 600 and 800 W), setting a total of 18 combinations. The configuration of z = 6 mm, v = 500 mm/s and P = 800 W resulted in a remelted pool with 710 µm width and 242 µm length without major porosities, therefore being the largest stable pool amongst all parameters combinations. The resulting cellular microstructure had an interphase spacing of 0.93±0.17 µm, a decrease of about 14 times in relation to that of the substrate. The effects of LSR on the microhardness were remarkable, with the remelted pool presenting Vickers microhardness of 49±2 HV which corresponds to an increase of about 40% when compared to the original substrate. |

Biomolecules and extracts from natural products are gaining increasing interest due to their beneficial properties for human health, low toxicity, environmental compatibility and sustainability. In this work, keratin, chitosan and peppermint essential oil have been used for the preparation of coatings on titanium substrates for biomedical implants/devices. All these coatings were obtained from local natural products/byproducts: keratin from discarded wool, chitosan from shrimps shells and peppermint essential oils from a local production. This approach supports a sustainable use of the resources and the sustainment of local economies with transformation of byproducts in high added values products. Keratin was chosen for its ability to stimulate soft tissue adhesion and to be easily doped with metal ions in order to confer antibacterial activity. Keratin coatings were realized as electrospun oriented/random submicrometric fibres or continuous films. Chitosan was selected for its anti-inflammatory and antibacterial properties. Continuous coatings were obtained with different grafting strategies (direct grafting, tresyl chloride activation or polydopamine addition). Peppermint essential oil was chosen for its antibacterial activity and used for the obtainment of continuous coatings based on the self polymerizing ability of terpenes. The coatings were characterized by means of SEM-EDS, FTIR, zeta potential, wettability, tape and scratch tests, cell and bacteria cultures. Coatings were successfully obtained for all the considered natural substances. Good adhesion to titanium substrates was reached through the optimization of the surface preparation/grafting process. All the coatings were chemically stable in water and the continuous coating were mechanically resistant and protective for the metallic substrates. The keratin coatings were hydrophilic while mint oil and chitosan coatings were hydrophobic. At physiological pH, keratin and mint oil coatings were negatively charged while chitosan ones were positively charged. The oriented keratin fibres were able to drive fibroblast alignment. Ag-doped keratin fibres and mint coating showed antibacterial properties. |
