| Description | FD-1080 free acid, an NIR-II region fluorophore (Ex=1064 nm, Em=1080 nm), facilitates in vivo imaging [1]. |
| In vitro | FD-1080在连续激光照射下展现出卓越的光稳定性。其量子产率为0.31%，与胎牛血清(FBS)结合形成FD-1080-FBS复合物后，量子产率可提高至5.94%[1]。 |
| In vivo | FD-1080在1064纳米NIR-II激发下展示了高于650纳米至980纳米NIR激发的深层组织穿透能力和卓越成像分辨率。借助此特性，实现了对小鼠活体左后肢血管、腹部和脑血管的深层组织和高分辨率成像，能够穿透完整的皮肤、组织和颅骨。FD-1080还能通过动态成像记录清醒及麻醉状态小鼠肝脏呼吸性头尾运动，从而定量监测呼吸频率[1]。 |
