Photoimmunotherapy is increasingly used to treat unresectable metastases, but many innovations are lost in translation due to heterogeneous treatment effects. This study integrates targeted nanotechnology, fluorescence-guided intervention, and a medical laser system to Continue reading →

Pioneering study confirms benefits of Modulight’s technology and photoimmunotherapy for ovarian cancer

A study published in Science Advances has for the first time scientifically demonstrated the potential of fluorescence-guided photoimmunotherapy enabled with Modulight’s laser platform and cloud technology. The study, a collaboration between the University of Maryland (UMD) and Modulight, confirms the benefits of targeted nanomedicine, Modulight’s medical laser system, and fluorescence-guided intervention in both achieving better treatment outcomes and predicting tumor response. “We have already published over a hundred scientific articles on our website from world-leading research groups that have used Modulight products in their studies.

Fluorescence endoscopy

Fluorescence endoscopyFluorescence endoscopy is the latest advancement in endoscopy technology, which uses specialized dyes to highlight specific areas of interest and provide better visibility and image quality during procedures. This technology has revolutionized the way we view the inside of the body, enabling doctors to obtain more detailed images of the gastrointestinal tract, lungs, bladder, and reproductive organs.Endoscopy Endoscopy is a powerful tool in diagnosing and treating a wide range of medical conditions. With its minimally invasive approach and high accuracy, it has become a Continue reading →

Fluorescence imaging & endoscopy for tumor visualization and diagnostics

Several fluorescent agents have been approved for fluorescence based diagnosis & intraoperative imaging: Dye generic name Countries Excitation Detection Indications Indocyanine Green (ICG) Worldwide 800 nm Near-infrared (820 nm) Multiple uses: lymphatic mapping, tissue perfusion, visualization of biliary ducts and blood veins, retinal angiography Fluorescein Worldwide 490 nm Green fluorescence (525 nm) Fluorescein angiography or angioscopy (ophthalmology) Methylene Blue Worldwide 665 nm 688 nm Endoscopic polypectomy, chromoendoscopy, lymphatic drainage 5-ALA Hydrochloride (converted to Pp-IX) Worldwide 400 – 410 nm Red fluorescence (620 – 710 nm) Continue reading →Introduction to fluorescence imaging Fluorescence is a phenomenon where substance that has absorbed certain wavelength of light emits it back at another wavelength. These substances are called fluorophores or fluorescent dyes. The emitted light has a longer wavelength than the absorbed one since some energy of the photon is lost in the process. The difference in wavelengths between absorbed and emitted light, called Stokes shift, allows very low background for fluorescence detection by separating it from the excitation light. The process of fluorescence generation is Continue reading →

Flow cytometry

Introduction Flow cytometry is a widely used method in biomedical research and increasingly also in clinical diagnostics. It is a powerful and rapid technique to analyze physical and chemical properties of single cells or particles as they are suspended in liquid and pass in a narrow line across laser beams. Fluorescence together with scattered laser light is then filtered, detected, and analyzed on the other side of the sample. In addition to analysis, many flow cytometers can also sort and purify cell populations of interest Continue reading →Introduction Flow cytometry is a widely used method in biomedical research and increasingly also in clinical diagnostics.
