Controllable preparation and high properties of fluorescence and surface enhanced raman spectra encoded poly(glycidyl methacrylate) microsphere

open access: yeseXPRESS Polymer Letters, 2019
Novel fluorescence and SERS encoded microspheres based on poly(glycidyl methacrylate) (PGMA) microspheres were developed by a controllable approach. The microspheres were encoded by four fluorescence dyes and three surface enhanced Raman spectra (SERS ...

Influence of the photonic nanojet of microspheres on microsphere imaging

open access: yesOptics Express, 2017
The imaging properties of BaTiO3 glass (BTG) microspheres in the diameter range of 5-50 µm which are fully immersed in a polydimethylsiloxane layer are experimentally studied. Our experimental results show that for both Blu-ray disc samples and the single-layer hexagonally close-packed microsphere array samples, with the increase of the diameter of BTG

Microsphere probe: combining microsphere-assisted microscopy with AFM

open access: yesOptics Express, 2023
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 ...

Formation and Characterization of Pseudo-Lignin Microspheres during High-pressure Water Pretreatment

open access: yesBioResources, 2015
Microspheres were generated after subjecting corn stem rind to high-pressure water pretreatment. These microspheres can be divided into two categories according to their location: free microspheres and adsorbed microspheres.
