Rodlike liquid metal gallium-based colloidal motors with broad light absorbance and photoluminance were prepared by a simple sonication crushing method. These colloidal motors could autonomously move at a speed of ca. 35 body lengths per second in the presence of an acoustic field, and could also actively seek and be internalized by cancer cells, which could be marked in real time through the photoluminance effect. Such liquid metal colloidal motors have promising applications in biomedical fields. More information can be found in the Full Paper by Qiang He et al.

通过简单的超声破碎方法制备了具有宽光吸收和光致发光的棒状液态金属镓基胶体电机。这些胶体马达可以以大约 10 倍的速度自主移动。在存在声场的情况下，每秒 35 个身体长度，并且还可以主动寻找并被癌细胞内化，这可以通过光致发光效应实时标记。这种液态金属胶体马达在生物医学领域具有广阔的应用前景。更多信息可以在 Qiang He 等人的 Full Paper 中找到。
