How to Make a Biocompatible Micro-Summer, Micro-Summer and How to Use These Micro-Summers

摘要

The present invention relates to a method of making a biocompatible micro-sweemer, the method comprising the steps of providing a photo crosslinkable biopolymer solution; Forming a solution capable of 3D printing by adding magnetic particles and a photoinitiator to the photocrosslinkable biopolymer solution; Applying a laser with a variable focus towards a 3D printable solution; Forming a biocompatible micro-sweemer having a predefined shape by changing the focus of the laser through the 3D printable solution; And applying a chemical linker to the biocompatible micro-sweemer having a predefined shape. The invention also relates to such micro-sweemers and methods of using such micro-swimers.
