NIR Fluorescence Captures Clear Images of Cancerous Tumors During Surgery
Despite the efficacy of surgery in cancer treatment, the disease can reappear. If the pathological report describes positive reactive margins in the area where surgery occurred, a second intervention may do more harm than good. Depending on the patient’s postoperative status, he or she may not be able to tolerate a second significant surgery. But near-infrared fluorescence can help to negate the need for more surgery.

Plasmonic Tip Detects Viruses’ Raman Signal
Scientists and health experts searching for a tool that will help in the diagnosis of COVID-19 today as well as prepare for the pandemics of tomorrow may soon find a solution in a suite of techniques based on the Raman effect. Raman spectroscopy relies on the optical read-out of rich and molecule-specific, fingerprint-like spectra of molecular vibrations. This technology can be applied to chemical identification and sensing. And now coherence-enhanced and plasmonic tip-enhanced Raman spectroscopies have been applied to diagnostics.

Opto-Refrigerative Tweezers Overcome Heat Damage to Particles
A tweak to optical tweezer technology introduced by researchers at the University of Texas at Austin fixes the problem of heat that affects the tool. The prolonged interaction with the laser beam can alter molecules and particles or damage them with excessive heat in optical tweezer technology. The tweak could lead to new research and simplify processes for using optical tweezers.

Fluorescent Sensors with Noncanonical Amino Acids Could Broaden Sensor Use in Biological Studies
Although fluorescence tools for biological study abound, some processes, such as the interactions between proteins and metabolites, are challenging to investigate with the tools that currently exist. However, a research group led by professor Jeremy Mills at Arizona State University (ASU) is working to change that by using a fluorescent noncanonical amino acid to generate new proteins.

Scientists Confirm Dynamin Molecular Motor’s Constriction Mechanism
A team at Kanzawa University used the measurement technique of single-molecule fluorescence resonance energy transfer, or smFRET, as well as a computable model, to develop a method that determined the strength of an individual dynamin motor. Dynamin, which refers to a family of biomolecules, is a protein that is a central player in endocytosis — a process that mediates the entry of diverse particles into cells, from nutrients to viruses. Its primary activity is to use guanosine triphosphate as fuel to constrict and cut membrane tubes.
