The editor and his collaborating authors have written a state-of-the-art reference on micro- and nanospheres with applications in physics. This useful book should be of interest to graduate students in physics, optics and biomedical engineering as well as researchers involved with nanotechnology.

Beyond an introduction to whispering-gallery modes (WGMs), which are necessary for light coupling in glass microspheres as optical resonators, the reader can easily progress to applications in high-resolution biosensing for detecting molecules, viruses and biomarkers. Application-oriented readers will also benefit from a chapter on optical WGM micro-resonators applied to microwaves and millimeter waves, as well as from sections on energy applications of glass microspheres that address hydrogen storage and targets for nuclear fusion.

Additional topics include optical frequency conversion in microspheres, like third-order sum–frequency generation and chemical synthesis of dielectric nanospheres, such as gold silica nanospheres for artificial opals as well as coatings for sensing applications. Furthermore, the development of microsphere lasers, glass beads and ball lenses should attract a wide readership.
