Biomining for Mother Nature’s Superlenses

Not Accessible

Your library or personal account may give you access

Abstract

Conventional optical microscopes are restricted by a predetermined limit beyond which it is impossible to resolve distinct points in the objective field. The origin of this limited resolution is associated to the optical diffraction and the loss of evanescent waves in the far field. As a result, objects below this diffraction limit, such as subcellular structures in biology and nanochips in semiconductors, cannot be seen. To overcome this problem, many solutions have been introduced over the past decades, comprising of super-oscillatory lens, Pendry negative index superlens, plus many more including our own all-dielectric superlenses which achieved a record resolution of 50nm in 2011 [1], and have since accomplished 45nm with mSIL in 2016 [2]. A problem accompanying many of today’s superlenses is the requirement for complex manufacturing processes, with chemical synthesis and photolithography. Subsequently, superlenses become inaccessible to non-professionals.
