Swimming upstream on sound waves (w/video)

Scientists have succeeded in propelling microvehicles against a fluid flow using ultrasound. In future, these tiny vehicles are set to be introduced into the human bloodstream, thereby revolutionising the field of medicine.

Assessing nanomaterial movements and nanomaterial-induced responses in lymphatic vessels

Nanoparticles used in drug delivery systems, bioimaging, and regenerative medicine migrate from tissues to lymphatic vessels after entering the body, so it is necessary to clarify the interaction between nanoparticles and lymphatic vessels.

Tuning electrode surfaces to optimize solar fuel production

An electrode material with modified surface atoms generates more electrical current, which drives the sunlight-powered reactions that split water into oxygen and hydrogen - a clean fuel.

In new step towards autonomous materials, researchers design patterns in self-propelling liquid crystals

Researchers have been developing 'active' materials that have the ability to move on their own. Now, they have taken the next step by showing that the movement in one such active material - liquid crystals - can be harnessed and directed.
