Automated Experimental Platform For Photonic Crystal Sensor Array

As a basic discipline,chemistry promotes the development and progress of human society.Despite rapid development,many chemical experiments still rely on frequent and complicated manual operations by scientific researchers.Moreover,too many manual operations have also brought some disadvantages,such as:the reproducibility of experimental results is not high,and some experimental operations are harmful to health.With the development of science and technology,automation technology has profoundly changed people’s production and lifestyle.At the same time,we believe that if these technologies are applied to the research and exploration of natural sciences,they will inevitably bring about a qualitative leap.In recent years,due to its periodic structure,photonic crystals have a photonic band gap,which can not only regulate the propagation of light,but also self-express signals,and has achieved rapid development in the field of new sensors.At present,the preparation of photonic crystals in the laboratory is done by manual operation,which not only requires high experimental experience,but also human error will cause the reproducibility of photonic crystal material preparation is not high,which will seriously affect the application and development of photonic crystals in the sensor field.Based on the potential application value of automation technology in scientific research,we decided to apply it to the practice of chemical experiments.We have built a set of automated experimental devices for photonic crystal sensor arrays,which can realize the automated preparation of photonic crystal materials by setting the experimental parameters of photonic crystal preparation under unattended conditions.Focusing on the automated preparation of photonic crystals,this paper has carried out the following two aspects of research work:(1)Designed and built a set of automatic preparation equipment for the photonic crystal positive template,and designed a set of corresponding software control programs for the automatic preparation equipment.Through the development of laboratory equipment:three-axis robotic arm,four-axis robotic arm,metal bath,injection pump and other equipment,the control of laboratory equipment has been realized.Through the automatic preparation device of the photonic crystal positive template,the automatic preparation of the photonic crystal positive template material has been successfully realized.The coding of the preparation steps of the photonic crystal positive template will help improve the repeatability and convenience of the preparation of the photonic crystal positive template material.(2)Based on the automatic preparation of photonic crystal positive templates,we designed and built a set of automatic preparation equipment for photonic crystal antitemplates,and designed a set of corresponding software control programs.Through the development of laboratory equipment:four-axis mechanical arm,6-channel switching valve,syringe pump,Lange pump,Xunfei pump,ultraviolet light source and other equipment development,the control of laboratory equipment has been realized.Through the automatic preparation device of the photonic crystal anti-template,the automatic preparation of the photonic crystal anti-template material has been successfully realized.The coding of the preparation steps of the photonic crystal antitemplate is realized,and the UI control interface is designed,and the automatic preparation of the photonic crystal anti-template can be conveniently carried out through reasonable parameter setting.Compared with traditional laboratory methods,the automated preparation device frees researchers from tedious experimental operations,significantly reduces experimental errors and improves the reproducibility of experimental results,showing the incomparable advantages of manual operation.It not only provides more abundant experimental information for scientific researchers,but also provides powerful tools for more experimental exploration in the future.
