The use of imaging technologies has been critical in deciphering biological phenomena,
structures, and mechanisms across a wide range of spatial scales. The spatial resolution of …

This review describes the growing partnership between super-resolution imaging and
plasmonics, by describing the various ways in which the two topics mutually benefit one …

The resolution of conventional optical elements and systems has long been perceived to
satisfy the classic Rayleigh criterion. Paramount efforts have been made to develop different …

In this article, we present an overview of aperture and apertureless type scanning near-field
optical microscopy (SNOM) techniques that have been developed, with a focus on three …

Heavy metal ions, such as Hg2+ and Ag+, pose severe risks in human health and the
environment. For sensitive detection and selective removal of Hg2+ and Ag+ ions, here, we …

The optical microscope is one of the oldest scientific instruments that is still used in forefront
research. Ernst Abbe's nineteenth century formulation of the resolution limit in microscopy let …

Nature is an important inspirational source for scientists, and presents complex and elegant
examples of adaptive and intelligent systems created by self-assembly. Significant effort has …

Biological and material samples contain nanoscale heterogeneities that are unresolvable
with conventional microscopy techniques. Super-resolution fluorescence methods can break …

Organelles are involved in many cell life activities, and their metabolic or functional
disorders are closely related to apoptosis, neurodegenerative diseases, cardiovascular …

Far-field chemical microscopy providing molecular electronic or vibrational fingerprint
information opens a new window for the study of three-dimensional biological, material, and …
