二维材料的分层是开发其独特性能的必要步骤。在这里，我们报告的形成稳定的胶体溶液的Ti3C2和Mo2Ti2C3MXene纳米片的堆叠多层MXene的存在下，白蛋白的分散和静电剥离。多层MXene分层成原子级薄的纳米片导致稳定的胶体溶液，由于白蛋白的吸附而具有良好的稳定性，这防止了少层纳米片的再聚集。级联离心用于产生单分散胶体。这项研究证明了一种可用于制备用于生物医学应用的MXene的加工方法。由于蛋白质吸附到纳米材料表面上在许多领域（包括医学、生物学、制药和环境工程）中起着重要作用，因此白蛋白涂覆的MXenes可以找到许多应用。
Delamination of two-dimensional materials is a requisite step for exploiting their unique properties. Herein, we report on the formation of stable colloidal solutions of Ti3C2and Mo2Ti2C3MXene nanosheets by the dispersion and electrostatic exfoliation of stacked multilayer MXenes in the presence of albumin. Delamination of multilayered MXenes into atomically thin nanosheets resulted in stable colloidal solutions with good stability due to the adsorption of albumin, which prevents re-aggregation of the few-layer nanosheets. Cascading centrifugation was used to produce monodisperse colloids. This study demonstrates a processing method that can be utilized to prepare MXenes for biomedical applications. Since protein adsorption onto nanomaterial surfaces plays a significant role in many fields, including medicine, biology, pharmaceuticals, and environmental engineering, albumin coated MXenes may find many applications.
