“…Figure 3d displays the amperometric responses on GOx/PtNPs-TH-MWCNTs (r TH-Pt = 0.10 : 1)/ Au at 0.5 V to successive additions of glucose, and the time required to reach 95 % of each steady-state response is within 5 s. The GOx/PtNPs-TH-MWCNTs (r TH-Pt = 0.10 : 1)/Au electrode exhibits a linear response to glucose in the concentration range from 1.65 mM to 11.1 mM (r 2 = 0.999), with a sensitivity of 0.14 A M À1 cm À2 and a detection limit of 0.05 mM (S/N = 3). The sensitivity here is probably the greatest one for first-generation GOx-based glucose biosensing to date [35][36][37][38].…”

Thionine (TH) adsorbed on multiwalled carbon nanotubes (MWCNTs) increases the load and dispersion of platinum nanoparticles (PtNPs) generated by chemical reduction of H 2 PtCl 6 with NaBH 4 . Under the optimum conditions, the PtNPs-TH-MWCNTs/Au electrode electrocatalyzed the reduction and oxidation of H 2 O 2 with high sensitivity, and after glucose oxidase (GOx) adsorption it responded to glucose concentration with a sensitivity of 0.14 A M À1 cm À2. The cyclic voltammetric cathodic peak current for NO 2 À reduction on PtNPs-TH-MWCNTs/Au responded linearly to NO 2 À concentration from 0.5 to 150 mM, with a sensitivity of 5.52 A M À1 cm À2 and a detection limit of 0.2 mM.

“…Additionally bio-devices with noble metal or nanomaterials, such as gold (Au), platinum (Pt) and Carbon nanotubes (CNTs) on the surface, are often used in bio-technology by exerting good functions like detecting antibody [1] or catalytic reaction [2]. And, the nano-structuration technologies for functional surface are also required to increase these functions [3]. Therefore, the process for the functional surface is importance in the fabrication of bio-and medical devices.…”

Abstract. Microforming has been received much attention in the recent decades due to the wide use of microparts in electronics and medical purpose. For the further functionalization of these micro devices, high functional surface with noble metals and nanomaterials are strongly required in bio-and medical fields, such as bio-sensors. To realize the efficient manufacturing process, which can deform the submillimeter scale bulk structure and can construct the micro to nanometer scale structures in one process, the present study proposes a combined process of microforming for metal foils with a selective chemical vapor deposition (SCVD) on the active surface of work materials. To clarify the availability of this proposed process, the feasibility of SCVD of functional materials to active surface of titanium (Ti) was investigated. CVD of iron (Fe) and carbon nanotubes (CNTs) which construct CNTs on the patterned surface of active Ti and non-active oxidation layer were conducted. Ti thin films on silicon substrate and Fe were used as work materials and functional materials, respectively. CNTs were grown on only Ti surface. Consequently, the selectivity of the active surface of Ti to the synthesis of Fe particles in CVD process was confirmed.

To demonstrate feasibility of this proposed process, feasibility of SCVD of functional materials onto active surfaces of titanium (Ti) was investigated. CVD of iron (Fe) and carbon nanotubes (CNTs) which construct CNTs on the patterned surfaces of the active Ti and non-active Ti oxidation layers were conducted.

Consequently, selectivity of the active surface of Ti to the synthesis of Fe particles in CVD was confirmed.
