Frontier Leadership Program for Engineering Students in Gunma University
Shunichi Ishijima,Naoto Shimizu,Tsuyoshi Masuda,Yoichi Seki,Seiji Tobita 한국공학교육학회 2012 공학교육연구 Vol.15 No.4
In this paper, the purpose and overview of the “Frontier Leadership Program for Engineering Students through Joint Participation of Higher Education and the Industrial Sector” (FLC: Frontier Leadership Course) in Gunma University is reported together with our achievements during the last three years. The purpose of this special educational program is to promote and educate selected students who are highly motivated to learn science & mathematics and to become an active leader in industrial sectors or research institutes. The activity can be divided into two categories: “Student-Proposed Stream” and “Advanced Research Stream”. These activities were found to be useful to cultivate student’s leadership and global communication ability. Furthermore, most of the FLC students cultivated the excellent academic performance and five students among them will be allowed to skip their fourth undergraduate year and enter directly into our graduate school.

<P>Colloidal Au-amplified surface plasmon resonance (SPR), like traditional SPR, is typically used to detect binding events on a thin noble metal film. The two major concerns in developing colloidal Au-amplified SPR lie in 1) the instability, manifested as a change in morphology following immersion in organic solvents and aqueous solutions, and 2) the uncontrollable interparticle distance, determining probe spacing and inducing steric hindrance between neighboring probe molecules. This may introduce uncertainties into such detecting techniques, degrade the sensitivity, and become the barricade hampering colloidal Au-based transducers from applications in sensing. In this paper, colloidal Au-amplified SPR transducers are produced by using ultrathin Au/Al<SUB>2</SUB>O<SUB>3</SUB> nanocomposite films via a radio frequency magnetron co-sputtering method. Deposited Au/Al<SUB>2</SUB>O<SUB>3</SUB> nanocomposite films exhibit superior stability, and average interparticle distances between Au nanoparticles with similar average sizes can be tuned by changing surface coverage. These characteristics are ascribed to the spacer function and rim confinement of dielectric Al<SUB>2</SUB>O<SUB>3</SUB> and highlight their advantages for application in optimal nanoparticle-amplified SPR, especially when the probe size is smaller than the target molecule size. This importance is demonstrated here for the binding of protein (streptavidin) targets to the probe (biotin) surface. In this case, the dielectric matrix Al<SUB>2</SUB>O<SUB>3</SUB> is a main contributor, behaving as a spacer, tuning the concentration of Au nanoparticles, and manipulating the average interparticle distance, and thus guaranteeing an appropriate number of biotin molecules and expected near-field coupling to obtain optimal sensing performance.</P> <B>Graphic Abstract</B> <P>An innovative colloidal Au-amplified surface plasmon resonance (SPR) transducer is achieved by a using remarkably stable and space-tunable Au/Al<SUB>2</SUB>O<SUB>3</SUB> nanocomposite film. This study indicates that the Au/Al<SUB>2</SUB>O<SUB>3</SUB> nanocomposite film is very promising; it simultaneously overcomes the instability and uncontrollable interparticle distance, which are the current bottlenecks hampering the application of SPR sensors. <img src='wiley_img/1616301X-2010-20-1-ADFM200901232-content.gif' alt='wiley_img/1616301X-2010-20-1-ADFM200901232-content'> </P>

<P>Monolayered Au/SiO<SUB>2</SUB> nanocomposite films with a high Au particle number density and insulating property were prepared by radio frequency magnetron co-sputtering to develop a new substrate for molecular conduction measurement. The topologies of Au nanoparticles distributed in the SiO<SUB>2</SUB> matrix were statistically evaluated by morphology observation using a field emission scanning electron microscope (FE-SEM) and the Voronoi diagram of a circle set by regarding the Au nanoparticles as a circle generator. The mean Au particle size and the interparticle distance between neighbours increased with deposition time. However, the fraction of the neighbouring Au nanoparticle combinations having interparticle distance shorter than a certain length increased as the deposition time increased. The results also demonstrated that many conducting paths several tens of nanometres long can be created by attaching conductive molecules 2.4?nm long between the Au nanoparticle combinations. Thus this suggests that the nanocomposite substrate can provide a facile way to measure conducting properties of molecules.</P>
