Microsphere—Toward Future of Optical Microscopes

Abstract

Optical microscope is one of the most widely used imaging tools for its great flexibility, reliable design, and low cost. Optical microsphere nanoscope (OMN) is invented as a method that can greatly enhance the observation power of conventional optical microscopes. In this perspective, the promising outlook for this approach is briefly discussed. There exists a great freedom to apply this method in various applications. OMN has been successfully commercialized. Our past experience and strategies are summarized in this perspective, which serves as a good reference for the future technology entrepreneurs. Based on our story and model, the factors for success are listed. It can be used to evaluate other commercialization projects and find out the directions that require further improvement.

The first scientific report on the function of the spherical lens was in the works of Seneca (4 BC–AD 65), which described the function of transparent spheres to produce a magnified image. The continuous development of optics then led to the invention of optical microscopes, which opened the gate for many scientific discoveries (Croft, 2006Croft W.J.
