Microsphere probe: combining microsphere-assisted microscopy with AFM.

In recent years, microsphere-assisted microscopy (MAM) and atomic force microscope (AFM) have been rapidly developed to meet the measurement needs of microstructures. However, the positioning of microspheres, the inability of AFM to touch the underlying sample through the transparent insulating layer, and the challenge of AFM fast positioning limit their use in practical measurements. In this paper, we propose a method that combines MAM with AFM by adhering the microsphere to the cantilever.

Thin head atomic force microscope for integration with optical microscope.

We present a novel thin head atomic force microscope (AFM) that can be easily integrated with an upright optical microscope (OM). The optical beam detection unit in the AFM used an obliquely incident laser beam onto the cantilever, reducing the AFM head's effective thickness to 7.3 mm.

Synthesis of two-dimensional TiCT/Au nanosheets with SERS performance.

This study proposes a new method for the preparation of novel MXenes/metal composites with unique chemical properties using reducing agent action. The effect of the reduction reaction time on the preparation conditions of ${{\rm Ti}_3}{{\rm C}_2}{{\rm T}_x}/{\rm Au}$TiCT/Au nanocomposites is studied, and the contribution of the prepared nanocomposites to the surface Raman reinforcement is analyzed. This study further explores the application of MXene in surface-enhanced Raman spectroscopy.
