After directly injected 10 nm golden nanoparticles (AuNPs) into the tarsal tunnel interstitial architecture of rats, AuNPs can be delivered to the brain bypassing the blood-brain barrier (BBB). With NaGdF4 NPs as agents, the magnetic resonance imaging (MRI) results displayed that the agents exited in the perivascular interstitial space of carotid arteries and brain vessels and demonstrated that the transportation to the brain was not through the blood circulation, but based on the interstitial architecture and interstitial stream. This kind of transportation exists throughout the whole body no matter in physiological or pathological status, which is the pathway not only connecting but also with high efficiency.

The stability of Li@atomic layer deposition (ALD)-carbon nanotube sponge (CNTS) electrodes relies on both the high-surface-area conductive framework and the robust ALD-Al2O3 surface protection layer, which decreases the effective areal current density and stabilizes the electrode/electrolyte interface for Li nuclei,respectively.

Near-infrared (NIR)-controlled cell adhesion: We constructed an NIR-responsive nano-biointerface by introducing a thermal responsive polymer onto a silicon nanowire array with photothermal property. The prepared nano-biointerface showed NIR-controlled reversible cell adhesion and release without the assistance of photosensitive moieties.
