(PhysOrg.com) -- The power and resolution of lens-based optical microscopes have improved by orders of magnitude since their invention around 1595. Nevertheless, relying on a high-magnification lens for image clarity has limitations that become more relevant as larger and larger sample volumes need to be viewed. Moreover, achieving these advances in lens-based optical microscopy has increased their size and complexity. At the same time, microfluidic systems are becoming increasingly sophisticated while decreasing in size, creating a need for miniaturized optical microscopy that can be integrated onto a lab-on-a-chip to allow simultaneous analysis and imaging of small biological samples.
