Abstract
Methods and systems are provided for aerosolization of individual building blocks of medical microrobots and subsequent in situ assembly into microrobots capable of medical intervention deep within lung tissues of a subject. The methods and systems of the disclosure may allow for microrobot-based therapy of pulmonary diseases that have previously been difficult to effectively treat using conventional therapeutic approaches.
Claims22
A method for delivering microrobots, comprising:
- (a) providing a liquid suspension comprising superparamagnetic particles of at least one microrobot building block;
- (b) aerosolizing the liquid suspension to form aerosolized droplets;
- (c) administering the aerosolized droplets into a target volume;
- and
- (d) applying a first magnetic field to the aerosolized droplets to cause the superparamagnetic particles to aggregate into microrobots in the form of microwheels.

A method for performing a medical intervention within a body of an animal subject, comprising:
- (a) providing a liquid suspension comprising superparamagnetic particles of at least one microrobot building block;
- (b) aerosolizing the liquid suspension to form aerosolized droplets;
- (c) administering the aerosolized droplets into a target volume within the body of the subject;
- and
- (d) applying a first magnetic field to the aerosolized droplets to cause the superparamagnetic particles within the target volume to aggregate into microrobots in the form of microwheels,
- wherein the microrobots are medical microrobots capable of performing a medical intervention within the target volume.
3 more elements
A system for delivering microrobots, comprising:
- a liquid suspension comprising superparamagnetic particles of at least one microrobot building block;
- a nebulizer, configured to aerosolize the liquid suspension to form aerosolized droplets and administer the aerosolized droplets into a target volume;
- and
- a magnetic actuation device, configured to apply a first magnetic field to the aerosolized droplets to cause the superparamagnetic particles within the target volume to aggregate into microrobots in the form of microwheels.
