Summary: Researchers developed a fluorescent nanozyme by doping Mn atoms into PbS/CdS quantum dots, which showed excellent antioxidant activity and could effectively scavenge ROS, thus providing neuroprotective effects for traumatic brain injury treatment. Additionally, the nanozyme exhibited exceptional NIR-IIb fluorescence performance, allowing for dynamic monitoring of the blood-brain barrier status to guide precise treatment.

Summary: In this study, a NIR PL nanoparticle TRZD was synthesized, which exhibited excellent rechargeable NIR PL in vivo and could be used for long-term autofluorescence-free imaging. TRZD could inhibit the tumor growth of glioma models and provide a promising multifunctional nanoparticle for theranostics of brain diseases.

Summary: The blood-brain barrier (BBB) is crucial for maintaining homeostasis within the brain and is increasingly associated with various neurological diseases. MRI techniques, such as dynamic contrast-enhanced and dynamic susceptibility contrast MRI, are commonly used for noninvasive assessment of BBB integrity. Other alternative techniques targeting different aspects of the BBB, such as using endogenous markers like water and glucose, are also available. A comprehensive overview of current MRI techniques to assess BBB condition and potential applications in disease is provided, with discussions on improvements needed for clinical applicability.

Summary: Gliomas are the most common primary brain tumors in adults, and the difficulty in accurately imaging and determining the malignancy grade of gliomas has significant impact on diagnostic accuracy and subsequent surgery or therapy. The rapid development of emerging nanoprobes provides a promising opportunity for the precise imaging and therapy of gliomas, enabling efficient crossing of the blood-brain barrier and targeted treatment. Challenges and future directions in nanoprobe-based diagnosis and treatment of gliomas are also discussed.

Summary: Optical nanosensors based on single-wall carbon nanotubes are able to capture the dynamics of biochemical processes. A one-step phase separation approach has been developed to isolate monochiral (6,4)-SWCNTs from mixed SWCNT samples, enabling high-resolution imaging in the near-infrared spectrum using standard Si-based cameras. (6,4)-SWCNTs modified with (GT)(10)-ssDNA become highly sensitive to the neurotransmitter dopamine, allowing for fast and high-resolution imaging of dopamine release from cells.
