Fluorescent Imaging: Smartphone Microscope Can Detect a Single Virus

Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair. Aydogan Ozcan, a professor of electrical engineering and bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, and his team have created a portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the need for bulky and expensive microscopes and lab equipment. The device weighs less than half a pound.

Using Liquid, Nanoscale Lenses to Detect Viruses or Nanoparticles

By using tiny liquid lenses that self-assemble around microscopic objects, a team from UCLA's Henry Samueli School of Engineering and Applied Science has created an optical microscopy method that allows users to directly see objects more than 1,000 times smaller than the width of a human hair.

Lensfree Optical Tomography

Light microscopy has traditionally relied on lenses to create microscopic images of small objects. Exploiting the recent advances in sensor technologies and digital processing algorithms, lensfree on-chip holographic microscopy takes a different approach to achieve high-resolution optical imaging without compromising the field-of-view. Along these lines, here we present a lensfree optical tomography approach for high-throughput on-chip 3D microscopy applications. more

Portable, Dual-Mode Microscope: Holograms Instead of Lenses

A compact, light-weight, dual-mode microscope that uses holograms instead of lenses have been built by researchers at the University of California at Los Angeles (UCLA), USA. To serve remote areas of the world, doctors, nurses and field workers need equipment that is portable, versatile, and relatively inexpensive. The team describes the new device in a paper published in the open-access journal Biomedical Optics Express.

Lens-free Optical Microscope: High-resolution 3-D Imaging on a Chip

A lens-free optical microscope system has been created by UCLA researchers. Without using a lens the scientists have redefined the concept of a microscope. The system is small enough to fit in the palm of a hand but powerful enough to create three-dimensional tomographic images of miniscule samples.
