Embodiment 1
[0041] The preparation method of the graphdiyne nanomaterial modified by bovine serum albumin comprises the following steps:
[0042] (1) the graphdiyne powder is placed in an agate mortar and ground for 10 min;
[0043] (2) the graphdiyne after grinding is dispersed in ultrapure water to form the aqueous solution of graphyne, and the aqueous solution concentration of graphyne is 1mg / mL;
[0044] (3) the graphdiyne aqueous solution is carried out ice-bath ultrasonic crushing in the ultrasonic crusher, the ultrasonic crushing time is 12h, and the crushing power is 400W, obtains the aqueous solution of the graphdiyne nanomaterial;
[0045] (4) the graphyne nanomaterial is dispersed in ultrapure water to obtain an aqueous solution of the graphyne nanomaterial, and the aqueous solution concentration of the graphyne nanomaterial is 1 mg / mL;
[0046] (5) dissolving bovine serum albumin in ultrapure water to obtain an aqueous solution of bovine serum albumin, the concentration of th...
