Overview

Optical microscopy, both transmission and
fluorescence, has limited spatial resolution due to well-known limits of
diffraction. In addition, few methods are available to increase spatial
resolution. The invention describes a novel and a simple method of
increasing optical resolution. The present technology can be
specifically used to image subwavelength features in the sample such as
cells, bacteria and integrated circuits etc.

Applications

Optical and/or fluorescence microscopy. Scanning
probe microscopy. Photolithography. Semiconductor manufacturing and
quality control.

Advantages

Offers high resolution imaging microscale objects
such as organelles inside the cell Better approach than that involving
lens with negative refraction materials. Allows imaging distant from the
film and throughout a subwavelength structure. (Ex. single cell)

Stage of Development

Proof of concept validated.
