Recently, researchers at the Federal University of Technology in Zurich, Switzerland, have developed the world's smallest autoinjector, called the "Liquid Force Microscope", which has a needle diameter of only one-fifth of the size of the hair, and can be directed to the cells without damaging the cells. Injection of drugs or deoxyribonucleic acid (DNA).
In this nano-scale auto-injector, there is a needle with a diameter of 200 nm. Under the microscope, the micro-pipette is activated, and the syringe can inject the drug into the cells. Researchers at the ETH Zurich said that the development of such nanoscale autoinjectors is a major advance in biological and pharmaceutical research, and it will have broad application prospects in the fields of medicine, chemistry and materials science.
Automated syringes are in the field of medical appliance technology and are safer, more clinical and economical than traditional syringes. Shanghai Medical Device Industry Association
