Received: 23 February 2019; Accepted: 10 March 2019; Published: 14 March 2019 Abstract: Conducting polymers (CPs) have attracted significant attention in a variety of research fields, particularly in biomedical engineering, because of the ease in controlling their morphology, their high chemical and environmental stability, and their biocompatibility, as well as their unique optical and electrical properties. In particular, the electrical properties of CPs can be simply tuned over the full range from insulator to metal via a doping process, such as chemical, electrochemical, charge injection, and photo-doping. Over the past few decades, remarkable progress has been made in biomedical research including biosensors, tissue engineering, artificial muscles, and drug delivery, as CPs have been utilized as a key component in these fields. In this article, we review CPs from the perspective of biomedical engineering. Specifically, representative biomedical applications of CPs are briefly summarized: biosensors, tissue engineering, artificial muscles, and drug delivery.

  • Glossary of Materials Engineering Terminology
    Glossary of Materials Engineering Terminology Adapted from: Callister, W. D.; Rethwisch, D. G. Materials Science and Engineering: An Introduction, 8th ed.; John Wiley & Sons, Inc.: Hoboken, NJ, 2010. McCrum, N. G.; Buckley, C. P.; Bucknall, C. B. Principles of Polymer Engineering, 2nd ed.; Oxford University Press: New York, NY, 1997. Brittle fracture: fracture that occurs by rapid crack formation and propagation through the material, without any appreciable deformation prior to failure. Crazing: a common response of plastics to an applied load, typically involving the formation of an opaque banded region within transparent plastic; at the microscale, the craze region is a collection of nanoscale, stress-induced voids and load-bearing fibrils within the material’s structure; craze regions commonly occur at or near a propagating crack in the material. Ductile fracture: a mode of material failure that is accompanied by extensive permanent deformation of the material. Ductility: a measure of a material’s ability to undergo appreciable permanent deformation before fracture; ductile materials (including many metals and plastics) typically display a greater amount of strain or total elongation before fracture compared to non-ductile materials (such as most ceramics). Elastic modulus: a measure of a material’s stiffness; quantified as a ratio of stress to strain prior to the yield point and reported in units of Pascals (Pa); for a material deformed in tension, this is referred to as a Young’s modulus. Engineering strain: the change in gauge length of a specimen in the direction of the applied load divided by its original gauge length; strain is typically unit-less and frequently reported as a percentage.

  • Alternative Tissue Engineering Scaffolds Based on Starch: Processing Methodologies, Morphology, Degradation and Mechanical Properties
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Universidade do Minho: RepositoriUM Materials Science and Engineering C 20 (2002) 19–26 www.elsevier.com/locate/msec Alternative tissue engineering scaffolds based on starch: processing methodologies, morphology, degradation and mechanical properties M.E. Gomes*, J.S. Godinho, D. Tchalamov, A.M. Cunha, R.L. Reis Department of Polymer Engineering, University of Minho, Campus de Gualtar, 4710-057 Braga, Portugal Abstract An ideal tissue engineering scaffold must be designed from a polymer with an adequate degradation rate. The processing technique must allow for the preparation of 3-D scaffolds with controlled porosity and adequate pore sizes, as well as tissue matching mechanical properties and an appropriate biological response. This communication revises recent work that has been developed in our laboratories with the aim of producing 3-D polymeric structures (from starch-based blends) with adequate properties to be used as scaffolds for bone tissue engineering applications. Several processing methodologies were originally developed and optimised. Some of these methodologies were based on conventional melt-based processing routes, such as extrusion using blowing agents (BA) and compression moulding (combined with particulate leaching). Other developed technologies included solvent casting and particle leaching and an innovative in situ polymerization method. By means of using the described methodologies, it is possible to tailor the properties of the different scaffolds, namely their degradation, morphology and mechanical properties, for several applications in tissue engineering. Furthermore, the processing methodologies (including the blowing agents used in the melt-based technologies) described above do not affect the biocompatible behaviour of starch-based polymers.

  • Optical Characterization and Properties of Polymeric Materials for Optoelectronic and Photonic Applications
    International Journal of Applied Science and Technology Vol. 3 No. 5; May 2013 Optical Characterization and Properties of Polymeric Materials for Optoelectronic and Photonic Applications A. N. Alias Z. M. Zabidi A.M.M. Ali M. K. Harun Faculty of Applied Sciences, Universiti Teknologi MARA 40450 Shah Alam, Selangor D.E Malaysia M.Z.A. Yahya Faculty of Science & Defence Technology, Universiti Pertahanan Nasional Malaysia, Kemsg. Besi, 57000 Kuala Lumpur Malaysia Abstract The optical properties of polymers attract considerable attention because of their potential optoelectronic applications, such as in polymer-based light-emitting diodes, light electrochemical cells, and solar cells. To optimize the performance of optoelectronic and photonic devices, some polymers are modified through the introduction of specific end groups, copolymerization, grafting, crosslinking, blending, and hybridization with other inorganic polymers. All these techniques affect the optical properties of the polymer. This paper reviews the fundamental emission and optical properties, such as absorption, reflection, and polarization effect, of numerous polymer materials. These aspects are important to be considered in optoelectronic devices. Introduction Polymers are widely used in electrical and electronic applications. In early works, polymers have been used as insulators because of their high resistivity and dielectric properties. Polymer-based insulators are used in electrical equipment to separate electrical conductors without passing current through themselves. The insulator applications of polymers include printed circuit boards, wire encapsulants, corrosion protective electronic devices, and cable sheathing materials [1]. Polymers have several advantages, such as easy processing, low cost, flexibility, high strength, and good mechanical properties. In the microelectronic fabrication industry, polymers are used in the photolithography process.

Some recent results of the authors are briefly presented. Keywords: controlled drug delivery systems; gene therapy; magnetic carriers; particulate polymer systems; POC-2014; stimuli-sensitive polymers. DOI 10.1515/pac-2014-0708 Introduction Significant human and financial resources have been always invested in medical research and development. Nowadays, the annual growth of sales for medical systems using biomaterials and the development of con- nected industries is, by far, one of the highest [1]. According to recent healthcare market research reports systems for drug delivery, diagnostics and regenerative medicine are among the global top ten medical device technologies. In this context, a major contribution to medical technologies comes from chemical engineering research, interfacing bioengineering and materials science. One main research direction is aimed at understanding how materials interact with the human body, i.e., twigging the factors affecting materials biocompatibil- ity and therapeutic efficiency, while another one is dealing with new biomaterials and devices to address unsolved medical problems. Specific requirements are to be met in the effort towards macromolecular materials with correct engi- neering, chemical and biological properties for the intended medical application.

The PC used in this work has a glass transition temperature of 145°C. We also characterize the mPOF optically and mechanically, and further test the sensitivity of the PC FBG to strain and temperature. We demonstrate that the PC FBG can bear temperatures as high as 125°C without malfunctioning. In contrast, polymethyl methacrylate-based FBG technology is generally limited to temperatures below 90°C. ©2016 Optical Society of America OCIS codes: (060.2370) Fiber optics sensors; (060.3735) Fiber Bragg gratings; (060.4005) Microstructured fibers; (060.2270) Fiber characterization; (160.5470) Polymers.
