Problems solved by technology

Non-degradable microrobots are relatively difficult to remove from their environment and are therefore not particularly well suited for in vivo applications
On the other hand, degradable microrobots may have a relatively weak structure, making them unsuitable for hosting cells, etc.

Embodiment Construction

[0076] figure 1 A method 100 of fabricating a magnetically actuatable microrobot 10 for carrying and delivering cells in one embodiment of the invention is shown. Microrobots can carry cells and more. In one exemplary application, during the path of vascular tissue, microrobots can be guided inside the tissue using real-time photoacoustic (PA) and ultrasound (US) imaging techniques, enabling high-resolution detection of optical adsorption.

[0077] The microrobot 10 is fabricated using an optimized photocurable composite material comprising: a degradable component configured to provide degradability of the microrobot, a mechanical mechanism configured to provide mechanical strength or support for the microrobot. Or structural components, and magnetic components configured to provide magnetic actuation capabilities that enable microrobots to respond to magnetic manipulation. The composition of microrobot materials can be optimized based on the application, especially conside...

Abstract

The invention provides a magnetically-drivable microrobot and a method of making the magnetically-drivable microrobot. The method is suitable for carrying and delivering cells and includes photo-curing a photo-curable material composition to form a body of the magnetically-drivable microrobot. The photo-curable material composition includes a degradable component, a structural component, a magnetic component, and a photo-curing facilitation composition including a photoinitiator component and a photosensitizer component.

Description

[0001] Cross Reference Related References [0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 055,963 filed on July 24, 2020 and priority to U.S. Patent Application No. 17 / 128,345 filed on December 21, 2020 rights, the entire contents of which are incorporated in this application by reference. technical field [0003] The present invention relates to a magnetically actuatable microrobot and a method for manufacturing the magnetically actuatable microrobot. Background technique [0004] Microrobots are commonly used for biomedical applications in both in vivo and in vitro settings because they are small and can be controlled relatively easily. Some existing biomedical microrobots are non-degradable, while others are degradable. Non-degradable microrobots are relatively difficult to remove from their environment and are therefore not particularly suitable for in vivo applications. On the other hand, degradable microrobots may have a rela...
