LMP1 gene detection using a capped gold nanowire array surface plasmon resonance sensor in a microfluidic chip.

Surface plasmon resonance (SPR) nanowire array chips with a microfluidic system are an effective detection method for a rapid test device. This study investigated a capped gold nanowire array and a microfluidic test platform to provide a fundamental understanding of the kinetic binding of SPR nanowires and the surface gold refractive index. The device sensitivity of the SPR nanowire array was 485 nm RIU-1 and the detection limit was 4.

A Smartphone-based Diffusometric Immunoassay for Detecting C-Reactive Protein.

In this study, we developed a portable smartphone-based diffusometry for analyzing the C-reactive protein (CRP) concentration. An optimized fluorescence microscopic add-on system for a smartphone was used to image the 300 nm fluorescent beads. Sequential nanobead images were recorded for a period and the image data were used for fluorescence correlation spectrometric (FCS) analysis.

Removal of benzene and toluene by carbonized bamboo materials modified with TiO2.

Carbonized moso bamboo (Phyllostachys pubescens) was coated with TiO(2) nanoparticles to enhance its removal efficiency of harmful gases. Carbonized bamboo-TiO(2) composite (CBC) was prepared by heating mixtures of carbonized bamboo powder (CB) and TiO(2) nanoparticles, denoted as CBM, under nitrogen condition. TiO(2) nanoparticle and carbonized bamboo powder were mixed with the mass ratios of 1/1 and 2/1, respectively.
