A team of researchers from the Beijing Institute of Technology has conducted a comprehensive study on carbon-based stimuli-responsive nanomaterials, exploring their potential use in medical diagnosis and treatment. The findings, published on March 9 in Cyborg and Bionic Systems, analyze these nanomaterials' adaptability to changes in their internal or external environments.

Stimuli-responsive nanomaterials have recently drawn scientific attention due to their adaptability and potential in biomedical applications. They respond to various stimuli, including pH, temperature, enzyme, redox reactions, light, magnetic fields, and ultrasound, making them versatile "smart materials". By modifying their physicochemical properties, these materials can effectively react to changes in their environments, opening up new opportunities in advanced smart nanomaterials development.

The research team's paper reviews the categorization and applications of these nanomaterials based on their microstructures and properties. They also discuss their use in diverse fields such as bioimaging, tumor therapy, and more. They have segmented carbon-based nanomaterials into three major categories: carbon nanotubes, carbon nanospheres, and carbon nanofibers. This classification not only elucidates the different types of nanomaterials but also highlights the distinct synthesis and preparation methods.

The researchers also delved into the diverse applications of carbon-based stimuli-responsive materials. The materials' unique optical properties make them highly valuable for anti-counterfeiting and optical imaging applications. When conjugated with targeted detection reagents, their sensitivity increases, making them useful for disease diagnosis. These nanomaterials also serve as drug delivery carriers or therapeutic agents for disease treatments, including photothermal, photodynamic, and chemotherapy.

Despite the promising prospects, the safety of carbon-based stimuli-responsive materials is not yet fully understood due to insufficient clinical trials. Therefore, the authors propose further research in toxicology, pathology, and biodynamics to bolster the credibility of these materials and quell controversy.

The study contributes significantly to the understanding of carbon-based stimuli-responsive materials, their classification, and their potential application in biology and chemistry. While further research is needed, the team is optimistic about future developments. They expect the creation of novel synthetic methods or composite materials that will enhance the safety of carbon-based stimuli-responsive materials, leading to substantial benefits for human health.
