About this book Introduction Integrated Biomaterials Science provides an intriguing insight into the world of biomaterials. It explores the materials and technology which have brought advances in new biomaterials, highlighting the way in which modern biology and medicine are synergistically linked to other key scientific disciplines-physics, chemistry, and engineering. In doing so, Integrated Biomaterials Science contains chapters on tissue engineering and gene therapy, standards and parameters of biomaterials, applications and interactions within the industrial world, as well as potential aspects of patent regulations. Integrated Biomaterials Science serves as a comprehensive guide to understanding this dynamic field, yet is designed so that chapters may be read and understood independently, depending on the needs of the reader. Integrated Biomaterials Science is attractive to a broad audience interested in a deeper understanding of this evolving field, and serves as a key resource for researchers and students of biomaterials courses, providing all with an opportunity to probe further.
A catheter may only have to perform for 3 days. A hip joint must not fail under heavy loads for more than 10 years. The bulk physical properties will also address other aspects of performance. To meet these requirements, design principles are borrowed from physics, chemistry, mechanical engineering, chemical engineering, and materials science.
Industrial Involvement Healing Special processes are invoked when a material or device heals in the body. Where a foreign body e. The normal response of the body will be modulated because of the solid implant. Thus, although we are now only learning about the fundamentals of biointeraction, we manufacture and implant millions of devices in humans. How is this dichotomy explained? Though the devices and materials are far from perfect, the complications associated with the devices are less than the complications of the original diseases.
Obviously, ethical concerns enter into the picture. Also, companies have large investments in the development, manufacture, quality control, clinical testing, regulatory clearance, and distribution of medical devices.
How much of an advantage for the company and the patient will be realized in introducing an improved device?
The improved device may indeed work better for the patient. Moreover, product liability issues are a major concern of manufacturers. Industry deals well with technologies such as packaging, sterilization, storage, distribution, and quality control and analysis. These subjects are grounded in specialized technologies, often ignored in academic communities, but have the potential to generate stimulating research questions.
Also, many companies support in-house basic research laboratories and contribute in important ways to the fundamental study of biomaterials science. Ethics A wide range of ethical considerations impact biomaterials science. Some key ethical questions in biomaterials science are summarized in Table 3. Some articles have addressed ethical questions in biomaterials and debated the important points Saha and Saha, ; Schiedermayer and Shapiro, Chapter Regulation The consumer the patient demands safe medical devices.
How can we best ensure informed consent? Companies fund much biomaterials research and own proprietary biomaterials. Antibiotics and Anti-inflammatory drugs A wide range of materials have been employed for the successful delivery of antibiotics, antiinflammatory drugs and growth factors.
A novel prodrug micellar based approach to deliver ibuprofen was demonstrated using polyethylene glycol-polypropylene fumarate self-assembled micelle nanostructures. A similar prodrug based approach involving supramolecular interactions between barium and ceramic has been evaluated for improving the stability and delivery of curcumin.
These pegylated quantum dots exhibit excellent compatibility coupled with augmented ability of delivering therapeutics.
A similar approach was also followed wherein chitosan nanoparticles were sulphonated and studied for the delivery of amphotericin B for the management of Candida glabrata fungemia. Additionally silk nanoparticles have been investigated for potential therapeutic applications. The antibiotic vancomycin loaded in silk fibroin nanoparticles entrapped in silk scaffolds resulted in continuous, pH dependent and sustained release patterns over a period of 30 days.
Radiographic and histopathological analysis performed to evaluate efficacy in treatment confirm reduced bone infection at defect site. Another study using natural silk protein nanoparticles obtained from oak tree Antheraea Pernyi evaluated the antibiotic delivery potential of drugs ibuprofen, and ibuprofen-Na and exhibited charge dependant release profiles. Studies also showed nanosized silicon incorporated HA exhibited morphological changes from rod to spherical and ribbon-like forms with increased silicon content.
These microwaves irradiated nanorods also exhibited excellent bioactivity and sustained release of amoxicillin. In vivo implantation studies on rat demonstrated greater bone formation in the drug-loaded delivery system compared to control at the end of 12 weeks.
Molecular docking results derived from the electrostatic and hydrophobic interactions of drug and chitin nanoparticle were successful in predicting encapsulation efficiency in the chitin-based host-guest nanosystems. The study effectively demonstrated that doxycycline hydrochloride, loaded in Tween 80 coated chitosan nanoparticles, can effectively cross the blood brain barrier for the treatment of psychosis in mice.
Upon subcutaneous implantation at distal site in rats, around For example, a multimodal contrast agent based on HA co-doped with europium and gadolinium enhanced paramagnetic longitudinal relaxivity suitable for magnetic resonance MR imaging coupled with excellent X-ray attenuation critical for X-ray contrast imaging.
In addition, administration of the nanoparticles in a subcutaneous mouse melanoma tumor model demonstrated significantly higher tumor cell death compared to free DOX.
Furthermore, biodistribution studies demonstrated augmented accumulation of DOX in tumor tissues in the nanoparticle treated group signifying delivery by passive targeting. The modulation of cellular signaling was evaluated and a dose dependent reduction in cell proliferation of PTEN expressing MCF7 cell was observed.
Primarily, imaging capabilities owing to bright blue luminescence and secondly, augmented cytotoxicity when compared to the free drug. These nanoclusters had exceptional stability in both PBS and serum and demonstrated augmented cytotoxic effects. It further resulted in higher amount of ROS generation and augmented oxidative stress induced apoptosis-mediated cellular death when compared to free drug.
The luminescence from the gold nanocluster was used to evaluate imaging and the boron component induced therapeutic effects towards HeLa and HepG2 cancer cells.
This manuscript was initially organized at Clemson University as classnotes for an introductory graduate course on biomaterials. Since then it has been revised and corrected many times based on experience with graduate students at Clemson and at Tulane University, where I taught for two years, , before joining the University of Iowa.
