The photochemical activity of black phosphorus (BP) in near‐infrared (NIR) light controlled in situ biomineralization is investigated. Owing to the excellent NIR absorption, irradiation with NIR light not only promotes degradation of BP into PO₄³⁻, but also enhances the chemical activity to accelerate the reaction between PO₄³⁻ and Ca²⁺ and promote in situ biomineralization. Mineralization of hydrogels is demonstrated by the preparation of BP incorporated hydrogel (BP@Hydrogel) which delivers greatly improved biomineralization performance under NIR illumination. The biomineralization process which can be controlled by modulating the light irradiation time and location has a high potential in controlling the mechanical properties and osteoinductive ability in tissue engineering. This study also provides insights into the degradation, photochemical activity, and new biological/biomedical applications of BP.

黑磷的光化学活性用于近红外光控制的原位生物矿化。

研究了黑磷（BP）在近红外（NIR）光下原位生物矿化控制下的光化学活性。由于优异的近红外吸收，近红外光照射不仅促进BP降解为PO ₄ ³⁻，而且增强化学活性以加速PO ₄ ³⁻和Ca ²⁺之间的反应并促进原位生物矿化。水凝胶的矿化通过掺入 BP 的水凝胶 (BP@Hydrogel) 的制备得到证明，该水凝胶在近红外照明下可大大提高生物矿化性能。可以通过调节光照射时间和位置来控制生物矿化过程，在控制组织工程的机械性能和骨诱导能力方面具有很高的潜力。这项研究还为 BP 的降解、光化学活性和新的生物/生物医学应用提供了见解。
