Probe vector for accurately detecting viruses as well as preparation method and application of probe vector

The invention discloses application of a probe carrier for accurately detecting viruses, which comprises the following steps: dispersing boron nitride nanotubes in deionized water, adding a nucleic acid primer to prepare a primer-nano material dispersion liquid, then adding a polyethylene glycol diacrylate solution, a polyethylene glycol solution and an ultraviolet light initiator solution, and uniformly stirring to obtain the probe carrier for accurately detecting the viruses. Preparing a first prepolymer solution; adding a nucleic acid probe into the dispersion liquid of the graphene oxide/carbon nanotube composite particles, then adding a polyethylene glycol diacrylate solution, a polyethylene glycol solution and an ultraviolet light initiator solution, uniformly mixing, and then adding an acrylic acid modified nucleic acid primer solution to prepare a second prepolymer solution; dropwise adding the first prepolymer solution onto a PDMS substrate for photo-crosslinking, and then dropwise adding the second
