An Implanted Tooth That Can Feel

Advanced Science, EarlyView.
To endow the implanted tooth with masticatory perception, herein we demonstrate that a 3D‐printed piezoelectric‐core/robust‐sheath implanted tooth can rebuild the sensing feedback, serving as “mechanoreceptors” in converting the mechanical chewing force to electrical signals, and up to brain through surrounding alveolar nerve system.

Liquid Metal Nanotransformers for Drug‐Resistant Pan‐Cancer Therapy in Patient‐Derived Organoids

Advanced Science, EarlyView.
Pan‐cancer therapies are severely limited in drug‐resistance patients due to genetic mutations and other factors, resulting in poor therapeutic outcomes and constrained clinical benefit. Liquid metal nanotransformers, a new class of shape‐transformable nanomaterials capable of dramatic morphological changes, offer a promising physical strategy to ...
