Lipid structure which has been highly focused on is black lipid membrane (BLM) because it is suitable for ion channel activity evaluation. However, BLM could not be arrayed without residual organic solvent and has a limitation of the low surface area which causes the poor probability of protein reconstitution. In this work, we fabricated solvent-free 3D lipid structure array on Si microwells, which has high surface area and uniformity. Also, we showed high reactivity of the proposed structure to one of pore-forming proteins, α - hemolysin (α HL), compared with BLM. This platform will pave the new way for biosensing applications which require high reactivity and sensitivity to target molecules.

The content consisted of three interactive parts, a smart phone application, a smart block and a family tree game board. We designed the content to cover an exercise therapy method, an emotional stimulation method and a memory training method for the cognitive rehabilitation of patients. Since our content includes various treatment strategies, it could be applied to develop effective cognitive rehabilitation contents for improving long-term memory, working memory, concentration and fine motor skill.

However most studies on laser ablation and treatment only considered laser operating conditions like wavelength, output power and pulse duration. The laser ablation arises from photothermal effect by photon energy absorption. Chromophores like melanin exist as the absorber in the skin. In this study, we painted color to mimic chromophores on in-vivo and in-vitro skin models to demonstrate influence on the laser ablation by skin color. Water-based pens were used to paint color. Cross sectional images of the laser ablation were acquired by Fourier-domain optical coherence tomography (Fd-OCT). Light source to make ablation was a Q-switch diode-pumped Nd:YVO4 nanosecond laser (532nm central wavelength). Irradiated light energy dose of the laser could not make ablation craters in the control group. However experimental groups showed craters with same irradiation light energy dose. These results show painting on skin increased tissue damage by absorption in painted color without dyeing cells or tissues.
