AI-based laser alignment for Flow Cytometry

Next generation flow cytometry Lasers have been historically the key light sources utilized in flow cytometry due to their ability to deliver the precise amount of energy needed to trigger the Stokes shift, which is the key phenomena underlying flow cytometry operation. For the same reason lasers and optical system in general are referred to as the “heart of flow cytometer”, since they are the integral component initiating the instrument operation. To ensure smooth and repeatable flow cytometer performance laser source needs to exhibit excellent Continue reading →

Photobiomodulation for pain treatment using ML6600

Background Photobiomodulation with low-level laser or light therapy is an effective treatment for pain. It has various effects, such as analgesic (pain-relieving) effects, anti-inflammatory effects, tissue regeneration promoting effects, and wound healing effects. Photobiomodulation can be used to relief both acute and chronic pain and has the advantage of being noninvasive and safe. Earlier studies have shown that photobiomodulation affects the activity of pain-transmitting nerves, even though the mechanisms are not fully understood. Because lasers are scattered and absorbed by biological tissues, the laser intensity Continue reading →Customer case University of Toyama is a Japanese national university located in Toyama City and Takaoka City and established in 1949.

Development of thermosensitive liposomes with the help of ML8500

Background The proper delivery and release of therapeutic drugs to a specific site or cell type is one of the main challenges in the treatment of diseases. Liposomes, which are vesicles composed of lipids, serve as carriers for drug delivery thanks to their long circulation time. This results to reduced toxicity in healthy tissues and improved therapeutic efficacy of encapsulated drugs. However, conventional liposomes can often be even too stabile, leading to insufficient drug release at the target site. Light activation can offer a solution Continue reading →Customer case Pharmaceutical Nanotechnology led by Professor Timo Laaksonen on controlled drug release and delivery using modern methods and materials. Particular interest lies in using light to both monitor nanomaterial behavior and to trigger e.g. drug release processes. Modulight products: ML8500, ML6600, MLAKIT Prof. Timo Laaksonen Dr. Tatu Lajunen Laser use: Light-triggered drug release studies from light-activated liposomes. ML8500 with 808 nm wavelength was used to induce the release of calcein from liposomes under different temperatures. The effect of different type of lipids on liposomal Continue reading →

Distributed Bragg Reflector (DBR) Laser Diodes

Introduction to DRB lasers Distributed Bragg Reflector (DBR) laser diodes are a class of single-frequency monolithic semiconductor lasers. Monolithic semiconductor lasers in general are small in size, mechanically robust, and have good power conversion efficiency. They also provide opportunities for hybrid integration with photonic integrated circuits (PICs). This application note provides an overview of DBR lasers, their principles of operation, their modal behavior, and their diverse applications. Principles of DBR Laser Operation A DBR laser is a semiconductor laser with one or several quantum wells Continue reading →
