In-vitro and in-vivo illumination

In Vitro and In Vivo illumination

Modulight provides a versatile and comprehensive product family for in-vitro and in-vivo illumination. Modulight lasers are used in many cell research laboratories worldwide to study photodynamic therapy (PDT). PDT utilizes photosensitizers that can be activated with specifically designed light sources – reactive oxygen is created at the target due to light activation.

Photosensitizers are also used in targeted drug delivery, and light activation is used for releasing the drug from the cargo. The PDT is on the verge of bringing another revolutionizing tool to be used in the treatment of glioblastoma, uveal melanoma, bile duct, pancreatic, and many other cancers.

Modulight’s in-vitro and in-vivo product family enables illumination of anything. We make lasers with variety of wavelengths, ranging from 400 to 2000 nm. Thus, we can support the research of all existing photosensitizers.

Photobiomodulation for pain treatment using ML6600

Customer case University of Toyama is a Japanese national university located in Toyama City and Takaoka City and established in 1949. It is comprised of 3 former national universities Toyama University, Toyama Medical and Pharmaceutical University, and Takaoka National College. Naoya Ishibashi Daisuke Uta Modulight products: ML6600 Laser use: Studying pain treatment with photobiomodulation. Links to articles:     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 Continue reading →

Phototruncation cell tracking with near-infrared photoimmunotherapy using heptamethine cyanine dye to visualise migratory dynamics of immune cells

Published in: eBioMedicine Authors: Hiroshi Fukushima, Aki Furusawa, Seiichiro Takao, Siddharth S. Matikonda, Makoto Kano, Shuhei Okuyama, Hiroshi Yamamoto, Peter L. Choyke, Martin J. Schnermann, Hisataka Kobayashi A new method called phototruncation-assisted cell tracking (PACT) can be used to noninvasively track migration of immune cells to understand anti-cancer immunity mechanisms. PACT is based on irreversible photo-induced truncation reaction, transforming Cy7 into Cy5 when exposed to NIR light (780 nm). PACT was used in this study to monitor spatiotemporal migration of immune cells between tumor and Continue reading →

Development of thermosensitive liposomes with the help of ML8500

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 →

Essential products for in vivo, in vitro, and preclinical applications

ML8500 – automated biomedical illumination device – provides targeted illumination for microplates. Each well is automatically and sequentially illuminated with a specific dose, irradiance and wavelength. Environmental parameters, like carbon dioxide content and temperature, can be adjusted. Optional fluorescence monitoring and cell imaging are also available. ML8500 supports various microplates (24/96/384/1536) and petri dishes. Illumination programs can be created remotely, and collecting data from the cloud can be conveniently done from the office – no need to control the illumination at the lab. Cloud connection enables also the remote support, service, and upgrades.

ML7710 is the most versatile oncology laser system for PDT studies, and the same product can be used for in-vitro/vivo studies and clinical therapies (CE mark, FDA approval for some combination therapies). The ML7710 is a cost-effective solution for long-term study plan including pre-clinical and clinical phases – using the same device from first phase studies to clinical tests makes regulatory work faster. The ML7710 is used already in many clinics and in well-known cancer centers worldwide. We provide internet connectivity, remote diagnostics, cloud services, and low-cost upgrades.

Modulight Illumination Kit is a series of accessories that enable uniform, parallel illumination of petri dishes and well plates. The whole sample plate is illuminated simultaneously in a specially designed illumination chamber. The laser light source can be an ML7710, or very compact but powerful ML6500 and ML6600 laser modules. ML6500 enables the use of one wavelength and ML6600 up to 3 wavelengths.  These laser sources can be used together with different light delivery options, e.g., SMA connected fiber with a frontal diffuser at the end. Most popular option among in vitro studies is to have our Illumination Kit sample stage that enables illumination of the well plate.

Modulight provides also many different and customized sample stage designs which can be tailored to fit any illumination target. We provide support for dose calculation and calibration, and our lasers have simple graphical user interfaces or they can be controlled from the computer. Products are supported with full suite of services from calibration to on-site training.

Illumination solution can be customized to your needs:

  • Wavelength can be selected between 400 – 2000 nm
  • Irradiance and dose can be adjusted
  • Different sample stages supporting the use of microplates, petri dishes, and possibility for customized
  • Handpiece enables in vivo subcutaneous illumination, option for spot size adjustment
  • We provide many different medical fiber options
  • Controlled and repeatable illumination, support for dose calculation
  • Possibility to use 1-8 different wavelengths
  • Pulsing possible in ms – µs range
  • On-site training
  • Regular calibrations and device support
