Abstract

The invention discloses a droplet microlens mixed solution and droplet microlens array preparation methods, a deformation method, an imaging method and a signal enhancement method. The droplet microlens mixed solution method comprises the steps: dropwise adding a droplet solution which is not dissolved in water into deionized water at a room temperature according to a volume ratio of 1: 9 to obtain a pre-solution; and putting the pre-solution into an ultrasonic oscillator, making oscillation for 2-10 minutes at a frequency of 20-80KHz, and taking out the oscillated solution to obtain a mixed solution with a droplet microlens. The preparation method disclosed by the invention is few in used materials, simple in process and short in time; and the prepared droplet microlens can be flexibly manufactured into a droplet microlens array as required; and controllable tensile deformation, sub-wavelength imaging of various experimental samples and enhancement of fluorescence signals can be performed.

Description

technical field [0001] The invention belongs to the field of optical technology, and relates to a droplet microlens mixed solution, a preparation method of a droplet microlens array, a deformation method, an imaging method, and a signal enhancement method. Background technique [0002] In microlens technology, dielectric microspheres are widely used in the fields of biophotonics and photochemistry because of their special optical properties. Traditional single dielectric microspheres have the disadvantages of limited mobility and small field of view when used directly as microlenses. Therefore, a microlens array film with dielectric microspheres embedded in elastomers is proposed to improve work Efficiency, but this method lacks flexibility for the detection of special target samples. Moreover, most of the existing dielectric microspheres used for spherical microlenses are solid materials such as silicon dioxide, titanium dioxide, or barium titanate. Most of the preparatio...
