Advances in biophotonic sensors: Revolutionizing medical diagnostics and research

Sponsored Content by Avantier Inc.Reviewed by Andrea SalazarJun 21 2024 Biophotonic sensors and systems are optical devices developed to deliver point-of-care diagnostics for medical practitioners and health researchers. They allow researchers to detect, sense, identify, and understand biological systems at the cellular/subcellular level, allowing them to gain a deeper understanding of biological processes, conditions, and molecular changes.

For example, the lab-on-a-chip biosensors developed in response to the global COVID-19 pandemic helped combat the virus. The early spread of the disease was, in part, a result of inefficient testing protocols, and health researchers across the world worked hard to find a quick, reliable way to determine the presence of the virus.

Optical coherence tomography in dermatology Previously, medical practitioners had to perform a biopsy to determine the presence of malignant tissue on the skin, but current optical coherence tomography technologies allow for a rapid, simple diagnosis without any skin excision. It can image skin to a depth of 2 mm, and resolution can be between 15 and 3 μm.Biophotonics can also be employed during surgery to ensure full removal of problematic tissue.

Deep learning algorithms can also conduct matrix multiplication containing millions of parameters, resolving complex equations that enable denoising, semantic segmentation, disease recognition, and even pseudostaining. Every day, breakthroughs in AI technologies are accelerating processing techniques and the potential of these analytical methods.
