Joint Work
Functional properties of the foundation and sunscreen products need to be long lasting because they are applied to the skin during long time in a day. Thus, the surface of the powder in cosmetics is coated with hydrophobic agents to make it water resistant. However, the water-resistant property of the powder makes it difficult to wash-off with water easily. To solve this problem, we focused on two types of poly(trimethylene carbonate) (PTMC) derivatives which show spontaneous surface rearrangements depending on wet or dry conditions. We found out that PTMC with poly(dimethylsiloxane) (PDMS-PTMC) and poly(ethylene glycol) monomethyl ether (mPEG-PTMC) showed change in contact angle because of the surface rearrangement of polymers under the wet condition. The response time under wet condition and change in contact angle were able to be controlled by the polymer chain length and blend ratio of PDMS-PTMC and mPEG-PTMC. PDMS-PTMC and mPEG-PTMC polymer-coated powder showed hydrophobic for a certain period, and then became hydrophilic after a certain period in water. Furthermore, by using a powder coated with PDMS-PTMC and mPEG-PTMC with the optimal polymer chain length and blend ratio for the powdery foundation, it is possible to develop a product that is both long lasting and easily wash-off.

A Rapid and Specific C-Reactive Protein Immunoassay Driven by an Electrophoresis System Based on Protein Enrichment in a 3D Filter Reviewed International coauthorship
Nanoscience and Nanotechnology Letters 9 ( 4 ) 425 - 432 2017.4
Joint Work
A rapid, sensitive and simple electrophoresis immunoassay was developed using a positive polyelectrolyte multilayer (PEM)-modified cellulose acetate (CA) membrane filter (PEM-CA). C-reactive protein (CRP), a cardiac and inflammation marker, was used as a measurement model. This rapid immunoassay was carried out using electrophoresis to drive the antigen movement, thus allowing local condensation of CRP in the proximity of an antibody-enriched PEM-CA filter. This overcame the diffusion resistance that normally dictates the time required for conventional ELISA. Moreover, electrophoresis could enhance the CRP specificity in a mixed solution of serum proteins because each protein has a unique electrophoretic velocity. The calibration curve for electrophoresis detection had a wide linear range of concentration from 0.013 to 50 nM, with a limit of detection of 33 pM, regardless of the presence of other proteins. The incubation time for antigen-antibody reaction was only 2 min, or about 1/30th of the time required for a conventional ELISA system. We conclude that this electrophoresis detection system should be developed further as a rapid, precise, and simple system for various immunosensors, using PEM-modified membrane filters.

Dual Electrophoresis Detection System for Rapid and Sensitive Immunoassays with Nanoparticle Signal Amplification Reviewed International coauthorship
Scientific Reports 7 42562 2017.2
Joint Work
An electrophoretic technique was combined with an enzyme-linked immunosorbent assay (ELISA) system to achieve a rapid and sensitive immunoassay. A cellulose acetate filter modified with polyelectrolyte multilayer (PEM) was used as a solid substrate for three-dimensional antigen-antibody reactions. A dual electrophoresis process was used to induce directional migration and local condensation of antigens and antibodies at the solid substrate, avoiding the long diffusion times associated with antigen-antibody reactions in conventional ELISAs. The electrophoretic forces drove two steps in the ELISA process, namely the adsorption of antigen, and secondary antibody-labelled polystyrene nanoparticles (NP-Ab). The total time needed for dual electrophoresis-driven detection was just 4 min, nearly 2 h faster than a conventional ELISA system. Moreover, the rapid NP-Ab electrophoresis system simultaneously achieved amplification of the specific signal and a reduction in noise, leading to a more sensitive NP-Ab immunoassay with a limit of detection (LOD) of 130 fM, and wide range of detectable concentrations from 0.13 to 130 pM. These results suggest that the combination of dual electrophoresis detection and NP-Ab signal amplification has great potential for future immunoassay systems.

Hydrophilic Polyelectrolyte Multilayers Improve the ELISA System: Antibody Enrichment and Blocking Free Reviewed International coauthorship
Polymers 9 ( 2 ) 51 - 64 2017.2
Joint Work
In this study, polyelectrolyte multilayers were fabricated on a polystyrene (PS) plate using a Layer-by-Layer (LbL) self-assembly technique. The resulting functional platform showed improved performance compared with conventional enzyme-linked immunosorbent assay (ELISA) systems. Poly(diallyldimethylammonium chloride) (PDDA) and poly(acrylic acid) (PAA) were used as cationic and anionic polyelectrolytes. On the negatively-charged (PDDA/PAA)3 polyelectrolyte multilayers the hydrophilic PAA surface could efficiently decrease the magnitude of the noise signal, by inhibiting nonspecific adsorption even without blocking reagent adsorption. Moreover, the (PDDA/PAA)3 substrate covalently immobilized the primary antibody, greatly increasing the amount of primary antibody adsorption and enhancing the specific detection signal compared with a conventional PS plate. The calibration curve of the (PDDA/PAA)3 substrate showed a wide linear range, for concentrations from 0.033 to 33 nM, a large specific signal change, and a detection limit of 33 pM, even though the conventional blocking reagent adsorption step was omitted. The (PDDA/PAA)3 substrate provided a high-performance ELISA system with a simple fabrication process and high sensitivity; the system presented here shows potential for a variety of immunosensor applications.
