摘要

Polymer-based flexible electrodes are receiving much attention in medical applications due to their good wearing comfort. The current fabrication methods of such electrodes are not widely applied. In this study, polydimethylsiloxane (PDMS) and conductive additives of carbon nanotubes (CNTs) were employed to fabricate composite electrodes for electrocardiography (ECG). A three-step dispersion process consisting of ultrasonication, stirring, and in situ polymerization was developed to yield homogenous CNTs-PDMS mixtures. The CNTs-PDMS mixtures were used to fabricate CNTs-PDMS composite electrodes by replica technology. The influence of ultrasonication time and CNT concentration on polymer electrode performance was evaluated by impedance and ECG measurements. The signal amplitude of the electrodes prepared using an ultrasonication time of 12h and CNT content of 5wt% was comparable to that of commercial Ag/AgCl electrodes. The polymer electrodes were easily fabricated by conventional manufacturing techniques, indicating a potential advantage of reduced cost for mass production.

Influence of Carbon Nanotube-Pretreatment on the Properties of Polydimethylsiloxane/Carbon Nanotube-Nanocomposites

Astrid Diekmann, Marvin C. V. Omelan, Ulrich Giese

Summary: Incorporating nanofillers into elastomers leads to composites with great potential, but concerns arise due to agglomeration of fillers. Different carbon nanotube pretreatment methods were analyzed to improve filler dispersion in polydimethylsiloxane (PDMS)/CNT composites. While solvent dispersion led to increased electrical conductivity, it also caused a softening effect due to solvent residues. Chemical functionalization improved compatibility but damaged CNTs, overshadowing the conductivity and reinforcement enhancement effects.

Preparation of g-C3N4/TNTs/CNTs Photocatalytic Composite Powder and Its Enhancement of Antifouling Performance of Polydimethylsiloxane Coatings

Gang Xiong, Zhanping Zhang, Yuhong Qi

Summary: Semiconductor photocatalytic materials have potential in antifouling applications due to their antibacterial properties, stability, and nontoxic nature. This study introduces g-C3N4/TNTs/CNTs (CNTC) photocatalytic composite powders into polydimethylsiloxane (PDMS) coatings to enhance their antifouling performance. The results show successful recombination of CNTC, which resulted in decreased recombination rate of photogenerated carriers. The addition of CNTC increased the hydrophobicity and roughness of the coatings while reducing the surface energy. CNTC effectively improved the anti-attachment performance of PDMS coatings to bacteria and benthic diatom.

Shuiliang Wang, Zhequn Huang, Wenbo Shi, Dongwook Lee, Qixiang Wang, Wen Shang, Yosi Stein, Yang Shao-Horn, Tao Deng, Brian L. Wardle, Kehang Cui

Summary: This study demonstrates that amine-containing aromatic and cyclohexane molecules can effectively disperse single-walled carbon nanotubes (SWCNTs) in solvents, leading to stable dispersion at the single-tube level. The interaction between the amine group of the molecules and the pi bond of SWCNTs plays a crucial role in achieving excellent dispersibility and stability. Additionally, the enhanced thermal and electrical properties of SWCNT/epoxy nanocomposites through the introduction of these molecules provide a promising new approach for industrial applications.

Cell culture design for homogeneous proliferation of cells in three-dimensional nonwoven polymer scaffolds

Yu-Min Chen, Chihoko Tokoda, Yasuhiko Tabata

Summary: The objective of this study is to establish strategies to uniformly proliferate cells in a three-dimensional nonwoven PET/EVOH scaffold by simple adjustments in seeding and culture methods and the scaffold design. The combination of dynamic and static seeding methods resulted in the highest seeding efficiency. Stirring culture allowed cells to proliferate to a greater extent, while opening holes in the scaffold improved cell distribution. Two 1-mm holes were found to be optimal for homogeneous cell proliferation. Different cell types showed similar behavior in the scaffold, indicating the applicability of the established procedure. The nonwoven PET/EVOH scaffold serves as a potential cell culture substrate for efficient cell proliferation.

Development of kojic acid loaded collagen-chitosan nanoparticle as skin lightener product: in vitro and in vivo assessment

Majid Saeedi, Katayoun Morteza-Semnani, Jafar Akbari, Seyyed Mobin Rahimnia, Fatemeh Ahmadi, Hanieh Choubdari, Amir Lotfi, Seyyed Mohammad Hassan Hashemi

Summary: In this study, kojic acid loaded chitosan/collagen nanoparticles were produced using an ionic gelation and ultrasonic approach to enhance dermal delivery and anti-pigmentation effects. Increasing the amount of collagen in the nanoparticles led to larger particle size and higher entrapment efficiency of kojic acid. The nanoparticles were found to be spherical in shape and kojic acid was in an amorphous form. Skin permeability tests showed that the nanoparticles delivered more kojic acid to the dermal layers compared to plain gel. The nanoparticles were non-toxic and non-irritating, and exhibited stronger inhibition of melanin formation compared to free kojic acid. These findings suggest that the produced nanoparticles have potential as a nano-vehicle for dermal administration of kojic acid, providing new options for managing hyper-melanogenesis problems.
