摘要：

Whispering-gallery-mode microresonators enable materials for single-molecule label-free detection and imaging because of their high sensitivity to their microenvironment. However, fabrication and materials challenges prevent scalability and limit functionality. All-glass on-chip microresonators significantly reduce these difficulties. Construction of all-glass toroidal microresonators with high quality factor and low mode volume is reported and these are used as platforms for label-free single-particle imaging. © 2016 WILEY-VCH Verlag GmbH & Co.
