The characteristics of nanoporous inorganic coatings on implants or on implantable devices are reviewed. The commonly used nanoporous materials, such as aluminum oxide (Al(2)O(3)), titanium oxide (TiO(2)) and porous silicon are highlighted with illustrative examples. The critical issues for sustained release systems are examined and the elution profiles of nanoporous coatings are discussed. The...

This paper presents a facile and efficient way to prepare carbon nanofibers ornamented with Au nanoparticles (Au/CNFs). Gold nanoparticles were first deposited in the channels of an anodized aluminum oxide (AAO) membrane by thermal decomposition of HAuCl4and then carbon nanofibers were produced in the same channels loaded with the Au nanoparticles by decomposition of sucrose at 230 °C. An elect...

The controlled production of magnetic nanowire arrays with outstanding characteristics is attracting much interest recently owing to their applications in emerging technologies related with magnetic information storage. Template electrodeposition is an efficient approaching method to fabricate these magnetic nanowires. In this paper, progresses and developments on the electrodeposition of magne...

Here, we present a systematic study about the effect of the pore length and its diameter on the specular reflection in nanoporous anodic alumina. As we demonstrate, the specular reflection can be controlled at will by structural tuning (i.e., by designing the pore geometry). This makes it possible to produce a wide range of Fabry-Pérot interferometers based on nanoporous anodic alumina, which a...

Atomic layer deposition (ALD) has been used in advanced applications where thin layers of materials with precise thickness down to the nanometer scale are needed. Using anodic oxidation, we prepared the porous alumina. Anodic oxidation was carried out in 5 C 0.3M oxalic acid with anodizing voltages (~ 40 V) and two step anodization method. SEM shows that, these porous anodic oxides are well ali...

We present a simple, efficient, and high-throughput methodology for the fabrication of ordered nanoporous polymeric surfaces with areas in the range of cm(2). The procedure is based on a two-stage replication of a master nanostructured pattern. The process starts with the preparation of an ordered array of poly(tetrafluoroethylene) (PTFE) free-standing nanopillars by wetting self-ordered porous...

Due to its special properties, amorphous carbon (a-C) materials have been reported to display novel functions for many potential optical [1,2], frictional [3] and electronic [2,4] applications. These include protective coating, ultra durable anti-reflection coatings [1,2], mechanical devices [2,3], and electron emitters [4]. The ability to fabricate a-C into desired physical shapes has attracte...
