Microstructure, Mechanical Properties, and Antibacterial Performance of Novel Fe‐Mn‐Zn Nanocrystalline Alloys Produced by Mechanical Alloying

Advanced Engineering Materials, EarlyView.
This article presents the development of Fe‐Mn‐Zn nanocrystalline alloys (0–9 wt% Zn) by mechanical alloying and subsequently hot pressing. Their microstructure, density, hardness, wear resistance, corrosion behavior, and antibacterial properties are systematically examined.

Gold Nanoparticles supported on MoS2 Nanoribbons matrix as a biocompatible and water dispersible platform for enhanced photothermal ablation of cancerous cells using harmless near infrared irradiation [PDF]

arXiv, 2014
With photothermal efficiency higher than traditionally used reduced graphene oxide, while simultaneously being water dispersible, we propose biocompatible Molybdenum Nanoribbons - gold Nanoparticles (MoS2 NR-Au NPs) system for synergistically enhanced photo-thermal ablation of cancerous cells (100% fatality) using NIR radiation (808nm), owing to ...

Instrumented cardiac microphysiological devices via multi-material 3D printing

Nature Materials, 2016
Biomedical research has relied on animal studies and conventional cell cultures for decades. Recently, microphysiological systems (MPS), also known as organs-on-chips, that recapitulate the structure and function of native tissues in vitro, have emerged ...

Enhanced Mechanical Properties of Injectable Chitosan–Guar Gum Hydrogel Reinforced with Bacterial Cellulose Nanofibers for Tissue Engineering Applications

Advanced Engineering Materials, EarlyView.
This study presents the development and characterization of injectable nanocomposite hydrogels based on N‐succinyl chitosan, oxidized guar gum, and bacterial cellulose nanofibers. Emphasizing enhanced mechanical properties and biocompatibility, the hydrogels exhibit fast gelation, improved structural integrity, and reduced swelling. Their potential for

In vivo biocompatibility of nanostructured Chitosan/Peo membranes

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2015
Electrospinning is a technique that allows the preparation of nanofibers from various materials. Chitosan is a natural and abundant easily obtained polymer, which, in addition to those features, proved to be biocompatible.

Biocompatibility of Blank, Post-Processed and Coated 3D Printed Resin Structures with Electrogenic Cells

Biosensors, 2020
The widespread adaptation of 3D printing in the microfluidic, bioelectronic, and Bio-MEMS communities has been stifled by the lack of investigation into the biocompatibility of commercially available printer resins.

Biocompatible Two-dimensional Titanium Nanosheets for Efficient Plasmonic Photothermal Cancer Therapy [PDF]

arXiv, 2018
Photothermal therapy (PTT) has shown significant potential in cancer treatment. However, developing nanomaterial-based photothermal agents with good biocompatibility and high photothermal conversion efficiency (PTCE) remains a key challenge. Titanium has been widely employed as biomedical materials based on their excellent biocompatibility.

Flexible and biocompatible microelectrode arrays fabricated by supersonic cluster beam deposition on SU-8 [PDF]

, 2010
We fabricated highly adherent and electrically conductive micropatterns on SU-8 by supersonic cluster beam deposition (SCBD). This technique is based on the acceleration of neutral metallic nanoparticles produced in the gas phase. The kinetic energy acquired by the nanoparticles allows implantation in a SU-8 layer, thus producing a metal-polymer ...
