JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Adding antibodies to photodynamic therapies can bolster their efficacy, according to research conducted by Texas A&M University and the University of São Paulo. The work reviewed the existing approaches to photodynamic therapies and provided a model to help expedite development of photodynamic therapies as a rapid response to emergent pandemics. In photodynamic therapy (PDT), photosensitizers composed of dyes and other light-reacting compounds are typically administered intravenously or are applied topically to the area where treatment is needed; they are then absorbed by...Read full articleRelated content from Photonics MediaARTICLESLaser-irradiated Coating Augments Nonsurgical Treatment of ObesityA multi-institutional research team in South Korea has enhanced the existing functionality of appetite-suppressing implants in the stomach with photodynamic therapy, coating such an implant with...BioPhotonics Jul/Aug 2022 IssueTemperature-based Method May Improve Detection of Skin CancerAn imaging technique developed by researchers at the Institut national de la recherche scientifique (INRS), can measure temperature in 2D, without contact, and in real time.

Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookWHITEPAPERSUnderstanding Virus Mechanisms – One Particle at a TimeSingle-molecule microscopy techniques facilitate direct study of molecular mechanisms, enabling leaps in understanding surrounding how viruses assemble, disassemble, and interact with their hosts.
