Abstract As a 2D metamaterial, metasurfaces offer an unprecedented avenue to facilitate light‐matter interactions. The current “one‐by‐one design” method is hindered by time‐consuming, repeated testing within confined space. However, intelligent design strategies for metasurfaces, limited data‐driven properties, have rarely been explored. To address this gap, data iterative strategy based on deep learning, coupled with global optimization network proposed, achieve the customized of chiral metasurfaces. This methodology applied precisely identify different molecules in label‐free manner. Fundamentally from traditional approach collecting purely through simulation, proposed generation encompasses entire space, which inaccessible conventional methods. dataset quality significantly improved, 21‐fold increase number structures exhibiting desired circular dichroism (CD) response (>0.6). method's efficacy validated monolayer structure that easily prepared, demonstrating advanced sensing abilities enantiomer‐specific analysis bio‐samples.

Terahertz scattering scanning near-field optical microscopy is a robust spectral detection technique with nanoscale resolution. However, there are still major challenges in investigating the heterogeneity of cell membrane components individual cells. Here, we present novel and comprehensive analytical approach for detecting at single-cell level. In comparison to resolution topographical atomic force image, spatial terahertz amplitude image 3 times that former. This ultrafine enables compositional distribution membrane, such as extracellular vesicles, be finely characterized. Furthermore, via extraction absorption images specific frequencies, visualization difference analysis can presented detail. These findings have significant implications intuitive visual development disease evolutionary pathways.
