Tools for Analyzing, Controlling, and Simulating Biological Systems
Tue, Sep 16, 2025 1:00 PM - 2:00 PM EDT
It was discovered that one can physically magnify biological specimens by synthesizing dense networks of swellable polymer throughout them, and then chemically processing the specimens to isotropically swell them. This method, which is called expansion microscopy, enables ordinary microscopes to do nanoimaging – important for mapping molecules throughout cells, tissues, and organs. As a second example, Ed’s team serendipitously discovered that microbial rhodopsins, genetically expressed in neurons, could enable their electrical activity to be precisely controlled in response to light. These molecules, now called optogenetic tools, enable causal assessment of how neurons contribute to behaviors and pathological states, and are yielding new candidate treatment strategies for brain diseases. Finally, the development of new strategies such as robotic directed evolution, fluorescent reporters enable the precision measurement of signals such as voltage. To reveal relationships between different molecular signals within a cell, there is work of developing spatial and temporal multiplexing strategies that enable many such signals to be imaged at once in the same living cell.

Metrology in Manufacturing: How Smart, Inline Metrology Can Set Your Optical Assembly Program Up for Success
Wed, Sep 24, 2025 11:00 AM - 12:00 PM EDT
A successful optical assembly program depends on meeting goals for quality, cost, and delivery. This session examines how optical metrology—when strategically integrated throughout the manufacturing process—can directly support these objectives. From incoming component inspection to in-process checks and final functional testing, participants will explore where metrology adds the most value and where it may introduce unnecessary cost or complexity. The presentation will offer a balanced view of both benefits and limitations, empowering manufacturers to make informed decisions about metrology deployment. Real-world case studies will illustrate practical applications, helping professionals translate theory into effective process improvements. This session is especially relevant for those in manufacturing, quality, NPI, and engineering roles responsible for optical or optomechanical assembly production. Presented by Optikos.

Battling Heart Disease with Photonics – With Yuqi Zhou
Photonic technologies are already being used to battle cardiovascular disease, but emerging technologies could further advance the treatment and diagnosis of the world’s leading cause of death. Yuqi Zhou is an assistant professor at the University of Tokyo and the lead author of a study on photonics and cardiovascular health. Sitting down with All Things Photonics, she discusses the potential of these systems and the hurdles they still face.
