MXenes are a class of 2D nanomaterials with versatile properties, but traditional synthesis methods produce nanosheets with varied sizes and multiple layers, limiting their effectiveness in applications such as bioimaging, biosensing, and photothermal therapy. This invention provides a process for synthesizing MXenes with a nanobipyramid morphology, resulting in ultra-small particles that offer increased surface area. This unique morphology enhances their suitability for biomedical and optical applications, particularly in biosensing and photocatalysis.
