Mami Aizawa; Hiroki Iwase; Toshio Kamijo; Akira Yamaguchi, Corresponding, The condensation of globular myoglobin (Mb) at the pore entrances of mesoporous silica (MPS) with a series of pore diameters (4.2, 6.4, 7.7, and 9.0 nm) was examined by differential scanning calorimetry (DSC) and contrast-matching small-angle neutron scattering (CM-SANS) experiments. The DSC measurements were performed to estimate the amount of Mb adsorbed at two different adsorption sites, namely, the pore interior and the pore entrance regions. The CM-SANS measurements were conducted to observe condensation of Mb molecules at the pore entrance regions. Notably, the nanopore entrance with a diameter close to twice that of the Mb diameter was found to be the specific cavity to facilitate the condensation of globular Mb. The Mb condensation occurred at the entrances of the 6.4 nm pore during the adsorption uptake from concentrated Mb solutions, whereas the adsorption uptake from diluted Mb solutions induced the condensation of Mb at the entrances of the 7.7 nm pore.
J. Phys. Chem. Lett., Sep. 2022, [Reviewed] - 〔Major achievements〕Giant Carbon Nano-Test Tubes as Versatile Imaging Vessels for High-Resolution and In Situ Observation of Proteins
Tracy T. Chuong; Toshihiko Ogura; Norihito Hiyoshi; Kazuma Takahashi; Sangho Lee; Keita Hiraga; Hiroki Iwase; Akira Yamaguchi; Kiyoto Kamagata; Eriko Mano; Satoshi Hamakawa; Hirotomo Nishihara; Takashi Kyotani*; Galen D. Stucky; and Tetsuji Itoh, Cryogenic electron microscopy is one of the fastest and most robust methods for capturing high-resolution images of proteins, but stringent sample preparation, imaging conditions, and in situ radiation damage inflicted during data acquisition directly affect the resolution and ability to capture dynamic details, thereby limiting its broader utilization and adoption for protein studies. We addressed these drawbacks by introducing synthesized giant carbon nano-test tubes (GCNTTs) as radiation-insulating materials that lessen the irradiation impact on the protein during data acquisition, physical molecular concentrators that localize the proteins within a nanoscale field of view, and vessels that create a microenvironment for solution-phase imaging. High-resolution electron microscopy images of single and aggregated hemoglobin molecules within GCNTTs in both solid and solution states were acquired. Subsequent scanning transmission electron microscopy, small-angle neutron scattering, and fluorescence studies demonstrated that the GCNTT vessel protected the hemoglobin molecules from electron irradiation-, light-, or heat-induced denaturation. To demonstrate the robustness of GCNTT as an imaging platform that could potentially augment the study of proteins, we demonstrated the robustness of the GCNTT technique to image an alternative protein, d-fructose dehydrogenase, after cyclic voltammetry experiments to review encapsulation and binding insights. Given the simplicity of the material synthesis, sample preparation, and imaging technique, GCNTT is a promising imaging companion for high-resolution, single, and dynamic protein studies under electron microscopy.

山口 央; 内田達也; 伊奈知美; 能智公久; 寺前紀夫, Lead, We have developed an apparatus for the measurement of second harmonic generation (SHG) spectra that provide direct evidence on the electronic structures of interfacial species. By applying the measurement apparatus, we have studied molecular association of rhodamine B (RB) at a heptane/water interface and trimethylchlorosilane (TMS) modified-quartz/water interfaces with a different coverage. The observed SHG spectra at the heptane/water interface showed red-shift of the peak maxima compared to the absorption maximum of monomeric RB in the bulk aqueous phase, and these spectra indicated predominant formation of in-plane associates in which the electronic transition dipoles of each monomer were arranged parallel to one another. At the TMS-modified-quartz/water interface, spectral shape of SHG spectra was almost same with that found in the heptane/water interface when the surface density of TMS was high. In contrast, with decreasing the surface density of TMS, the red-shifted peak due to the in-plane associates become weaker, and other peaks due to a sandwich dimmer appeared. We confirmed that the association form of RB depended on the surface density of TMS., The Japan Society for Analytical Chemistry

In this study, we demonstrate that the Au particle modified probe DNA monolayer can enhance the surface plasmon resonance (SPR) signal for measuring hybridization of unlabeled DNA molecules. The Au particles adsorbed on single stranded (ss)- and double stranded (ds)-DNA monolayers have different optical interaction with surface of Au thin film, and this difference induces the enhancement of the SPR signal., Oxford University Press (OUP)
Chemistry Letters, 01 Feb. 2002, [Reviewed] - Photo-electrochemical Deposition of Platinum on TiO2 with Resolution of Twenty Nanometers using a Mask Elaborated with Electron-Beam Lithography
Saulius Juodkazis; Akira Yamaguchi; Hidekazu Ishii; Shigeki Matsuo; Hitoshi Takagi; Hiroaki Misawa, We report the patterning of Pt on a TiO2-rutile single crystal (the fundamental absorption band starts at 396 nm) by direct deposition from a water solution of H2PtCl6 (10–20 mmol/dm3) using laser beam writing at 390–396 nm, or by Hg-lamp illumination (i-line at 365 nm). Pt deposition was corroborated by microchemical analysis. A resolution of the Pt patterning down to 20-30 nm was achieved. To create a Pt pattern with resolution of twenty nanometers, we employed a mask elaborated with electron-beam (EB) drawing lithography. The mask was transparent to the writing illumination. The Pt was reduced from the solution by laser beam scanning over resist-covered regions, while the pattern was formed in the openings of the resist. Separation of the growth and illumination regions, typically, by 0.5–2 µm, facilitates the deposition of reproducible, high-aspect-ratio patterns. It is demonstrated that Pt was deposited through a process of diffusion of the light-excited carriers. The possibility of fabrication of a three-dimensional Pt pattern by the overgrowth of the resist is discussed., IOP Publishing
