What is it about?
The COVID-19 pandemic has been disruptive in many ways. But, it had one silver lining: it united research communities in a search for solutions. They made a significant global effort to improve existing healthcare technologies. One such faction contributed to optical technologies. In a study, researchers marked out two pathways to help: 1. Develop quick solutions to address pressing needs. 2. Develop solutions for the future. These would help develop formulate the treatment for COVID-19; it would accelerate vaccine development as well. A new study explores these advancements. It tells us how photonics research has helped us deal with the pandemic. What did the authors find? The immediate solutions worked on improving disease control. This included fabrication of protective equipment, like: • Face masks and face shields; • Respirators for healthcare workers who were in close contact with those infected. Optical technologies proved useful in infection control as well. In fact, one of these, ultraviolet radiation, was among the CDC recommended methods for disinfection. Among the longer term solutions offered by optics, one was diagnosis and screening. Some optical techniques, like quantitative PCR, were indispensable in the diagnosis of COVID-19. Optics majorly contributed to screening for the disease as well. For example, pulse oximeters detected oxygen saturation. Infrared sensors detected fever. These signs helped screen suspected cases of COVID-19.

Why is it important?
Optical technologies have been almost omnipresent in the pandemic. They've helped in multiple areas and continue to do so. Further research in this field hints at a combination of optics and artificial intelligence (AI). This would increase the accuracy of existing technologies. How would that help us? AI with optics could result in accurate diagnostics. This increased accuracy aids clinicians in their treatment planning. It helps screen and monitor those with COVID-19. It could help automate infection control. The prospects are endless! KEY TAKEAWAY: Optics have helped in many ways during the COVID-19 pandemic. The field offered a chance to repurpose existing technologies in a short time. This way, it provided useful solutions to help manage the pandemic. Optics has contributed to improved infection control, diagnostics, and therapeutic development. It continues to do so and might be with AI in the future. This would vastly improve the accuracy of optical technologies.

Making microscopes affordable with a single lens and machine learning
While single lenses have difficulty focusing different colors, they can take detailed single-color images. By adding color to these images using machine learning, this study could make low-cost microscopes a reality.
Detecting multiple COVID-19 signatures at the single molecule level
The new sensing device designed by the authors can help us detect and prevent the spread of COVID-19 as well as other infectious diseases.
Artificial Intelligence: Could it be a game-changer in our fight against COVID-19?
AI has the potential to revolutionise healthcare. But for this to happen, our AI technology first needs improvement.
Internet of medical things: How can it help during pandemics?
The cost of healthcare services is growing worldwide. Developing IoMT and addressing its shortcomings will help ensure better medical care during the COVID-19 pandemic and beyond.
Switching targets from virus to host: an alternative approach for drug development
Targeting the host instead of the coronavirus can help develop more successful therapies with fewer side effects.
New sensor makes virus testing quicker and less invasive
Access to fast, accurate, and affordable diagnosis of COVID-19 infection is essential to contain the spread of viruses and prevent major outbreaks. A new biosensor could help reduce the seriousness of current and future viral infection outbreaks.
Rapid advances in diagnosis of COVID-19
New types of testing lend themselves better to cheap, quick, hand-held devices; smartphones are also helping to improve testing as well as things like monitoring and contact tracing.
