Summary: With the advancement of nanotechnology, nanozymes have emerged as potential substitutes for natural enzymes due to their unique properties of nanomaterials, such as high activity, easy preparation, low cost, and robust stability. However, the constant activity of nanozymes in biomedical applications poses a potential threat to normal tissues. To address this issue, stimuli-responsive nanozymes have been designed to manipulate their activities. This review discusses two types of stimuli-responsive nanozymes, including those with stimuli-switchable activities and those exhibiting responsive release from specific carriers. The biomedical applications of stimuli-responsive nanozymes in cancer therapy, antibacterial therapy, biosensing, and anti-inflammatory therapy are also briefly explored. Finally, the challenges and prospects in this field are addressed.

Summary: Ceria nanoparticles can induce the generation of nitric oxide in addition to scavenging it. This study demonstrates that ceria nanoparticles catalytically decompose S-nitrosoglutathione to produce nitric oxide, with a high release recovery rate and maintained crystalline structure. The newly discovered capability of ceria nanoparticles to generate nitric oxide from GSNO overturns the conventional concept of their role solely as NO-scavenging agents, and shows potential therapeutic effects in cancer cell suppression.

Summary: The study shows that CeO2 as a fuel-borne catalyst can reduce emissions and improve combustion efficiency. CeO2 significantly reduces soot and THC emissions at low load, but not as much at high load. A minor reduction in NOx emissions is observed at high load, with no significant difference in fuel consumption.
