METHOD OF MAKING A BIOCOMPATIBLE MICRO-SWIMMER, MICRO-SWIMMER AND METHOD OF USING SUCH A MICRO-SWIMMER

摘要

The present invention relates to a method of making a biocompatible micro-swimmer, the method comprising the steps of: providing a photo cross-linkable biopolymer solution; adding magnetic particles and a photo initiator to the photo cross-linkable biopolymer solution to form a 3D-printable solution; applying a laser with a variable focus directed at the 3D-printable solution; varying the focus of the laser through the 3D-printable solution to form the biocompatible micro-swimmer with a predefined shape; and applying a chemical linker to the biocompatible micro-swimmer having the pre-defined shape. The invention further relates to such a micro-swimmer and to a method of using such a micro-swimmer.
