Two-photon dyes for real-time imaging of lipid rafts are provided. The two-photon dyes emit fluorescence with high intensity in the environments of cell membranes and can be used to clearly discriminate the hydrophobic and hydrophilic domains of the cell membranes. Therefore, the use of the two-photon dyes enables satisfactory imaging of actual lipid raft domains. In addition, since the two-photon dyes show no cytotoxicity, they can be suitably used in bioimaging applications, for example, real-time imaging of lipid rafts over a long period of time.
提供了用于实时成像脂质微囊的双光子
染料。这些双光子
染料在细胞膜环境中发出高强度的荧光,可以清晰地区分细胞膜的疏
水和亲
水区域。因此,使用双光子
染料可以令人满意地成像实际脂质微囊区域。此外,由于双光子
染料不显示细胞毒性,它们可以适当地用于
生物成像应用,例如长时间的实时成像脂质微囊。
