Smart Probe Captures Biomarker Sequence
A smart probe is a hairpin oligonucleotide, essentially a string of nucleic acids, that is labeled with a fluorophore on one end and tethered with successive guanosine residues on the other end. Extrinsic dye labels with suitable absorption are typically used for fluorescence quenching, which signals a reaction. But recent research has shown that guanosine moieties can provide effective fluorescence quenching for common fluorescent dyes due to guanosine’s low oxidation potential. Thus, guanosine is used as a quencher in smart probes, which can detect biomarkers of cancer and other conditions.

Multiplex Imaging Captures Cellular Processes
Ongoing innovations in optical microscopy have fueled life science research, allowing scientists to visualize how complex biological systems work and break down. These developments have required specifications beyond the need for high-resolution views of cells, tissues, organs, and organisms. There is also an ongoing search for new microscopy tools that are fast enough to capture high-speed motion pictures of biological dynamics and to have a high enough throughput to interrogate large populations of cells for unravelling the intricate cellular heterogeneity. Most importantly, the tools need to be gentle enough to ensure minimal risk of photodamage for monitoring long-term biological processes.

Laser-based Photoacoustic Method Provides Subcellular Insights
City University of Hong Kong researchers developed a multiwavelength optical resolution photoacoustic microscopy system based on a single laser source. The system enables simultaneous multicontrast imaging of hemoglobin concentration, blood flow speed, blood oxygen saturation, and lymphatic concentration. Information, at the level the new system is able deliver, provides subcellular insights useful for the study of disease models, such as in cancer research.

Light-Controlled Nanoparticles Support Noninvasive Nanomedicine
Scientists from ITMO University have developed a production method for bio-integrated optical nanomaterials based on Mie-resonant silicon nanoparticles. The nanoparticles used in the work are covered by biopolymer shells and can be controlled by heat. With light irradiation, the particles change their shape and color. The discovery is poised to support nanophotonic and nanomedicine applications and the development of noninvasive biosensors, signal systems, and nontoxic dyes.

Virginia Tech Lands $2.4M Grant to Optically Measure Brain Activity
Researchers at the Fralin Biomedical Research Institute at Virginia Tech Carilion School of Medicine received a $2.4 million National Institutes of Health grant to use optically pumped magnetometry to explore neural activity during face-to-face human interactions. The researchers will optically measure the brain’s magnetic signals in two research volunteers simultaneously as the volunteers interact, capturing the nuances of the brain’s signaling in real time.

Nanoflashlight Could Turn Mobile Devices into Powerful Biosensors
Researchers at MIT built a device that they describe as a “nanoscale flashlight” on a chip. Much like a spectrometer, the MIT team’s nanoflashlight shines a beam of light on a material, analyzes the light after it has passed through the material at several wavelengths, and captures the interactions of light with the material for each color.

Freeform Optics for Imaging: Manufacturing Methods
Thu, May 27, 2021 1:00 PM - 2:00 PM EDT
In this talk Matt Davies, Ph.D., of UNC Charlotte, and John Lambropoulos, Ph.D., of the University of Rochester, discuss the current methods employed for manufacturing freeform optics, as well as those methods’ comparative strengths and the limitations. In particular, they examine the need for post-processing (finishing) and its interactions with other manufacturing steps and methods. Part 2 of the 2021 Freeform Optics Series.
