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 →

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 →

Effects and side-effects of plasmonic photothermal therapy in brain tissue

Published in: Cancer Nanotechnology Authors: Yue He, Kristoffer Laugesen, Dana Kamp, Salik Ahmad Sultan, Lene Broeng Oddershede, Liselotte Jauffred    Published in: Cancer Nanotechnology Authors: Yue He, Kristoffer Laugesen, Dana Kamp, Salik Ahmad Sultan, Lene Broeng Oddershede, Liselotte Jauffred   Laser was used for plasmonic photothermal therapy (PPTT) studies using gold nanoshells in brain tissue phantom and different porcine cerebral tissues. The electromagnetic field of a laser beam resonates with the plasmonic field of the nanoparticles, which absorb the incident light. The absorbed energy is dissipated as heat and causes hyperthermia in tumor.   Read the article here

Platinum nanoparticles: a non-toxic, effective and thermally stable alternative plasmonic material for cancer therapy and bioengineering

Published in: Nanoscale Authors: Akbar Samadi, Henrik Klingberg, Liselotte Jauffred, Andreas Kjær, Poul Martin Bendix, Lene B. Oddershede    Published in: Nanoscale Authors: Akbar Samadi, Henrik Klingberg, Liselotte Jauffred, Andreas Kjær, Poul Martin Bendix, Lene B. Oddershede   They have used laser to study effectiveness of platinum nanoparticles (PtNPs) for photothermal cancer therapy using ovarian cancer cell lines. They demonstrated that PtNPs are non-toxic themselves but upon laser irradiation kill effectively cancer cells.   Read the article here
