The use of ionic implantation in the synthesis nano palladium for biosensors

Abstract

The rapid development of biosensor technologies and the expansion of the requirements determine the necessity for scientists to search of new materials and new technologies.1–5 Moreover, these problems are caused not only by the interest of scientists in this topic, but also by an increase attention of industrial and medical workers.6 The development of biology, pharmacy, medicine and, in particular, biochemical and biophysical methods of analysis and control leads to the search for new designs of electrochemical, photosensitive, thermal sensors and biosensors.3,7–9 Recently, a promising direction in biosensor material science is the use of nanomaterials, such as nanoparticles, nanocomposites, nanotubes, etc.3,4,7,8,10 The most common non-organic components of nanoparticles are precious metals (Au, Pt, Pd) deposited on various supports (steel, polymer, etc.).3,4,7,8 However, the effectiveness of biosensors also depends on the technology of active particles producing. In this respect, ionic implantation proved to be very successful. This technology permits to modify the surface layer of various materials –supports (most often metals, alloys) by introducing target ions (Ti, Ni, Cr, Al, etc.)11–14 and thereby create substrates for the active components deposition. Thus, the aim of the work is to study the possibility of ionic implantation using in the synthesis of palladium nanoparticles in the aspect of obtaining materials for biosensors.
