As Biosensors Shrink, Their Potential Applications Grow
Early in his career, Benjamin Miller was focused on drug discovery and strategies for studying how potential medicines bind to their target proteins. There was only one problem: “All of the technology that was available for doing that was terrible,” said Miller, a biochemist and engineer at the University of Rochester. “So, we decided to start working to fix the problem.”

Quantitative Phase Microscopy Tracks Drug Therapies
Examining the cycle of life through the lens of a microscope is a fundamental practice in biology. As researchers have delved deeper into the microscopic world, a pursuit for higher resolution has ensued, leading to discoveries about the smallest constituents within cells. It was during this quest that the significance of light’s informational content became apparent, and some of the latest innovations in quantitative phase microscopy are tapping into this in a variety of applications.

Wavelength-specific Index Guides Laser Skin Treatment
Laser treatment has gained popularity for the treatment of skin blemishes. To improve the efficacy and reduce complications from laser treatment, a research group led by Osaka Metropolitan University developed an index of the threshold energy density, or fluence, for melanosome disruption, corresponding to the dependent wavelengths of the picosecond lasers used for treatment. The wavelength-specific irradiation index will help clinicians determine the optimal endpoint for pigmented lesion treatment based on numerical indicators.
