报告摘要：
Laser-induced deposition (LID) is introduced as a powerful and versatile paradigm for creating nanostructured surfaces decorated with active metal nanoparticles, addressing urgent societal needs in healthcare, ecology, and food safety. The performance of next-generation optical and electrochemical sensors hinges on the controlled creation of such functional matter, and LID uses light as the primary synthetic tool to achieve this. By illuminating the interface between a substrate and a metal precursor solution, LID triggers a heterogeneous redox process that directly writes metal nanoparticles onto target surfaces. Precise control over laser parameters (wavelength, time) and precursor chemistry (metal type, concentration, solvent) enables fine tuning of nanostructure morphology and functionality. This laser-based synthesis is universally applicable, allowing hybrid materials to be created on diverse substrates, from flexible polymers to complex 3D architectures like silicon nanowires. Ultimately, LID transcends conventional fabrication as a versatile strategy for optically synthesizing functional matter on demand. We showcase the direct outcomes through LID-fabricated substrates that serve as high-performance SERS and electrochemical sensors for eco-toxicants and bioanalytes, including beta-amyloid, anthracene, glucose, paracetamol, and dopamine.
