Abstract

Provided are a protein-matrix microlens array diffraction device and a preparation method thereof. The protein-matrix microlens array diffraction device includes a matrix of a protein crystal. A largest side of the protein crystal has a length of 100 to 500 μm, a surface of the protein crystal where the largest side is located is processed to have an array of microlens-like protrusions, a distance p between two adjacent microlens-like protrusions of the array of microlens-like protrusions is in a range of 10 to 100 μm, a diameter d of the microlens-like protrusion is in a range of 2 to 10 μm, and a height h of the microlens-like protrusion is in a range of 0.05 to 2 μm.
