In 1874, the company was commissioned to manufacture the kilogram reference standard, made from 90% platinum and 10% iridium, and held in the Bureau International des Poids et Mesures ( International Bureau of Weights and Measures), and copies of it for international distribution. The company had branches in the cities of Birmingham and Sheffield to supply the jewellery and silverware and cutlery trade with raw materials and ancillary supplies, such as silver solder and flux, which it manufactured. The following year the firm was appointed official assayer and refiner to the Bank of England. In 1851 George Matthey joined the business and its name was changed to Johnson & Matthey. Johnson Matthey traces its origins to 1817, when Percival Norton Johnson set up business as a gold assayer in London. It is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index. Written in the highly successful Methods in Molecular Biology™ series format, chapters include introductions to their related topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.Īuthoritative and accessible, Nanotechnology in Regenerative Medicine: Methods and Protocols provides established scientists, junior researchers, and students involved in the bioengineering, biotechnology, and biomedical fields with a sound foundation in a variety of vital nanotechnology approaches in regenerative medicine.Johnson Matthey is a British multinational speciality chemicals and sustainable technologies company headquartered in London, England. Being that the application of nanotechnology to regenerative medicine is a very broad field, this book focuses its interests on particular areas such as its use as a means to produce efficient platforms and structures for tissue engineering, delivery systems and biosensors, as well as the use of some techniques to study materials surfaces and the interactions between cells, biomolecules, and surfaces at the nanoscale. In Nanotechnology in Regenerative Medicine: Methods and Protocols, expert researchers in the field provide an overview of a very wide range of currently used technologies and methods that involve nanotechnology principles applicable to tissue regeneration. Nanotechnology plays a key leading role in developing tools able to identify, measure, and study cellular events at the nanometric level as well as in contributing to the disclosure of unknown biological interactions and mechanisms, which opens the door for advances including nanodevices for diagnostic and therapy, drug delivery systems, and regenerative medicine.
