摘要:
A display sheet includes a display layer that has a first display layer having multiple first containers each containing a first electrophoretic particle group and a second display layer disposed on one surface side of the first display layer and having multiple second containers each containing a second electrophoretic particle group. Each of the multiple first containers overlaps at least one of the multiple second containers in a planar view of the display layer.
摘要:
There is provided an ICG-loaded polymer nanoparticle that is dynamically stable, prevents the leakage of contained ICG and the resulting discoloration, and has a high molar absorbance coefficient. The particle contains a hydrophilic dye having a sulfonate group and a hydrophobic polymer, and the particle further contains at least one of a lipid having a positively charged region, a nicotinic acid derivative and a thiamine derivative.
