摘要

摘要在这项工作中，制备了掺铜碳纳米粒子，其发射光谱范围很宽，并能在磁共振成像过程中改变水质子的弛豫时间。据我们所知，铜纳米粒子的弛豫度 r1 值最高，达到了 0.92 mM-1 s-1。所提出的碳纳米粒子是很有前途的生物成像双模态纳米探针。

Copper-Doped Carbon Nanoparticles as a Two-Modal Nanoprobe for Luminescent and Magnetic Resonance Imaging

In this work, copper-doped carbon nanoparticles with emission in a wide spectral range and the ability to change the relaxation times of water protons during magnetic resonance imaging were fabricated. A high relaxivity value r1 = 0.92 mM^–1 s^–1 was achieved, which is the highest value of r1 for copper nanoparticles, to our knowledge. The suggested carbon nanoparticles are promising two-modal nanoprobes for bioimaging.
