The present invention provides a two-dimensional material nanosheets with a large area and a controllable thickness and a general preparation method therefor. As an intralayer heat transfer coefficient of a two-dimensional material is much higher than an interlayer heat transfer coefficient thereof, the two-dimensional material is uniformly heated and sublimated layer by layer by controlling the energy of the laser pulses, a thinning thickness is controlled by adjusting the action time of the laser pulses, and finally, a two-dimensional material film with a controllable thickness is obtained. At the same time, a sample displacement stage moving freely in a two-dimensional plane space can realize preparation of the two-dimensional material film with a large area. Compared with traditional methods, the present invention can control a sample thickness of the two-dimensional material film, has a high generality, and is suitable for all kinds two-dimensional materials.

Disclosed is a method of obtaining a protein-associated nanostructured complex (MRB-CFI-1) by chemical synthesis and antitumor use. The main use is in treating cancer, both in animals and humans. The complex has singular antitumor activity, and can potentially be used as a substitute and/or act as an adjuvant for other commercial antineoplastic drugs.
