In chemical biology , bioorthogonal chemical reporter is a non native chemical functionality that is introduced into the naturally occurring biomolecules of a living system , generally through metabolism metabolic or protein engineering . These functional group s are subsequently utilized for tagging and visualizing biomolecule s. Prescher & Carolyn R. Bertozzi , the developers of bioorthogonal chemistry , defined bioorthogonal chemical reporters as non native, non perturbing chemical handles that can be modified in living systems through highly selective reactions with exogenously delivered probes. It has been used to enrich protein s and to conduct Proteomics proteomic analysis. In the early development of the technique, chemical motifs have to fulfill criteria of biocompatibility and selective Chemical reaction reactivity in order to qualify as bioorthogonal chemical reporters. Some combinations of proteinogenic amino acid side chain s meet the criteria, as do ketone s and aldehyde s which can tag proteins and some metabolism metabolite s . Azide s and alkyne s are other examples of chemical reporters. A bioorthogonal chemical reporter must be incorporated into a biomolecule . This occurs via metabolism . The chemical reporter is linked to a Substrate chemistry substrate , which a cell biology cell can metabolism metabolize . References cite journal author Prescher, J. A. Carolyn R.

Onesource date December 2007 Biotextiles are structures composed of textile fibers designed for use in specific biological environments where their performance depends on biocompatibility and biostability with cell biology cell s and biological fluids . Biotextiles include implantible devices such as surgical suture s, hernia repair fabrics, artery arterial Medical grafting grafts , artificial skin and parts of artificial heart s. They were first created 30 years ago by Dr. Martin W. King, a professor in North Carolina State University s College of Textiles http www.tx.ncsu.edu faculty center directory detail.cfm?id 63 . Medical textiles are a broader group which also includes bandages, wound dressings, hospital linen, preventive clothing etc. Antiseptic biotextiles are textiles used in fighting against cutaneous bacteria l proliferation. Zeolite and triclosan are at the present time the most used molecules. This original property allows to fightinhibits the development of odours or bacterial proliferation in the diabetic foot. New developments In the new paradigm of tissue engineering , professionals are trying to develop new textiles so that the body can form new tissue around these devices so it s not relying solely on synthetic foreign implanted material.

In surgery , a biocompatible material sometimes shortened to biomaterial is a synthetic or natural material used to replace part of a living system or to function in intimate contact with living biological tissue tissue . Biocompatible materials are intended to interface with biological systems to evaluate, treat, augment or replace any tissue, organ anatomy organ or function of the body. Biomaterials are usually viability non viable Disambiguation needed date February 2012 , but may also be viable. A biocompatible material is different from a biological material such as bone that is produced by a biological system . Artificial hip s, vascular stent s, artificial pacemaker s, and catheter s are all made from different biomaterials and comprise different medical devices . Biomimetic materials are not made by living organisms but have compositions and properties similar to those made by living organisms. The calcium hydroxylapatite coating found on many artificial hips is used as a bone replacement that allows for easier attachment of the Implant medicine implant to the living bone . Surface functionalization may provide a way to transform a bio inert material into a biomimetic or even bioactive material by coupling of protein layers to the surface , or coating the surface with self assembling peptide scaffolds to lend bioactivity and or cell attachment 3 D matrix. Different approaches to functionalization of biomaterials exist. Plasma processing has been successfully applied to chemically inert materials like polymer s or silicon to graft various functional group s to the surface of the implant. Polyanhydrides are polymers successfully used as a drug delivery materials. Care should be exercised in defining a biomaterial as biocompatible, since it is application specific. A biomaterial that is biocompatible or suitable for one application may not be biocompatible in another.

The company specializes in applying hard coating to a wide range of substrate materials using a PVD process Physical vapor deposition . Depending on the application, different coating film materials can be produced, such as TiN Titanium nitride , TiC, TiNC grey, antracite, black , AlTiN violet, black or DLC Diamond Like Carbon . The coating is mainly used for industrial applications based on the different properties of the materials. However, the PVD process results in a finish such that many coatings are equally suitable for decorative purposes. In addition to their production, Micromy also conducts research in the T by facility. One of the applications of their research results is a new surface layer called micronite . Compared to conventional PVD coatings, micronite has outstanding tribological and corrosive properties. The coatings offered by Micromy include coatings approved for medical use under the guidelines of the United States Food and Drug Administration FDA . As such, they are suitable for sensitive applications like implants or drug manufacturing parts where biocompatibility is a requirement or where abrasive residue must be strictly controlled. Micromy offers a low temperature variant of the PVD process that makes it applicable for metal objects prone to heat deformation, or even polymer materials. Although most of the revenue is generated from contract work on customer objects or substrates, Micromy also offers a small portfolio of their own articles.

With wide ranging uses from Natural environment environment friendly biodegradable composites to biomedical composites for drug gene delivery, tissue engineering applications and cosmetic orthodontics . They often mimic the structures of the living materials involved in the process in addition to the strengthening properties of the matrix that was used but still providing biocompatibility, e.g. in creating scaffolds in bone tissue engineering. Those markets are significantly rising, mainly because of the increase in oil price, and recycling and environment necessities. Biocomposites are characterised by the fact that the petrochemical resin is replaced by a vegetable or animal resin, and or the bolsters fiberglass , carbon fibre or talc are replaced by natural fibre wood fibres, hemp , flax , sisal , jute ...

Bioceramics range in biocompatibility from the ceramic oxides , which are inert in the body, to the other extreme of resorbable materials, which are eventually replaced by the materials which they were used to repair. Bioceramics are used in many types of medical procedures. A primary medical procedures where they are used is Implant medicine implants ref J.F. Shackelford ISBN 0 87849 822 2 ref . This article is primarily concerned with rigid materials commonly used as Implant medicine surgical implants , though some bioceramics are flexible. The ceramic materials used are not the same as porcelain type ceramic materials. Rather bioceramics are closely related to either the body s own materials, or are extremely durable Mixed metal oxide metal oxides . History Prior to 1925 the materials used in implant surgery were primarily relatively pure metals. However these are not considered to be ceramics and are therefore outside the scope of this article. The success of these materials was surprising considering the relatively primitive surgical techniques.
