ML8500 – automatic biomedical illumination


Automatic Biomedical Illumination System

ML8500 is the world's most versatile illumination device for in-vitro studies. ML8500 can support up to 7 different wavelengths simultaneously, flexible control of illumination parameters, and built-in incubation chamber for cells studies in normoxic and hypoxic conditions.

Automatic system for illuminating well plates

ML8500 is a great tool for sequential illumination of multi-well sample plates and optional fluorescence imaging/measurement. Prepare your samples, load into ML8500, and fully automatic system takes care of the rest. Operating the biomedical illumination system is very easy with an intuitive touch screen interface and Modulight’s cloud.

The system supports multiple illumination stations that illuminate different sized areas in the sample. For example, one station can be for Petri dish that is up to 95 mm in diameter and another for 96-well plates that illuminates each well separately with specific duration and intensity. Different illumination stations can be delivered for various well plates (24, 96, 384, 1536 wells) and a total of 4 illumination stations can be fitted in one system.

Device can be further equipped with environmental control for optimized cell-based assays. Hypoxia feature also enables conducting cell experiments in physiologically relevant conditions, since tumors are often hypoxic which affects the efficacy of oxygen-dependent therapies like photodynamic therapy.

Flexible illumination of single wells or larger areas with ML8500

ML8500 supports illumination of individual wells as well as as larger areas on a well plate. This enables both flexibility of parameter control between samples, as well as significant time savings when running illumination protocols with many samples.

ML8500 case examples

ML8500 in developing standardized photosafety screening for FDA

The Huang Laboratory in the University of Maryland Fischell Department of Bioengineering (BIOE) has partnered with Modulight Corp. to establish new standardized guidelines for drug photosafety testing using Modulight ML8500.

ML8500 automatic system for illuminating well plates will be used and further optimized to serve as a platform for the standardized drug phototoxicity screening. ML8500 will also support big data acquisition, analysis, and sharing in Modulight Cloud ecosystem.

Development of heat shock protein 90-targeted PDT for inflammatory breast cancer

Background: A novel photo-activated drug, HS Here, a novel targeted drug was developed for breast cancer by combining clinically approved verteporfin with a small molecule inhibitor of heat shock protein 90.

Modulight’s solution with ML8500: ML8500 was used to study optimal parameters for drug’s activation in a high-throughput manner. Highly aggressive MDA-MB-231 breast cancer cells were seeded on 96-well plates, incubated with different concentrations (0-3 µM) of either verteporfin or HS201, and illuminated with 689 nm wavelength laser at various doses (0-30 J/cm2) in different wells. Also different drug-light intervals (0, 3, and 6 hours) were studied with escalating light doses (0-120 J/cm2).

Osmium-based anticancer photosensitizer with highest hypoxic activity reported to date

Background: Hypoxia presents a major challenge in the treatment of cancer, as low oxygen conditions make malignant tissues simultaneously more aggressive and less susceptible to standard treatments. To address this issue, a novel hypoxia-active photosensitive drug was developed for treatment of hypoxic tumors.

Modulight’s solution with ML8500: ML8500 provided optimal conditions for characterization of the drug using 525 nm and 630 nm wavelengths. In the first experiment, irradiance was constant at 300 mW/cm2 and fluence was varied between 10-300 J/cm2, while in the second experiment, fluence was at 100 J/cm2 and irradiance varied 25-300 mW/cm2 mW/cm2mW/cm2.

Fully automated illumination study series for modern cancer drug development

Background: The study of photoactivated drugs requires a controlled and systematic sample illumination process.

Modulight’s solution with ML8500: Novel photosensitive drug was characterized for a pharmaceutical company using ML8500 automated illumination system connected to ML7710 medical laser. The goal was to investigate the effect of irradiance and light dose on a cancer cell line while keeping the photosensitive drug dosing constant.

Development of thermosensitive liposomes with the help of ML8500

Motivation: Passive drug release from liposomes is erratic and inefficient, so light-triggered release offers attractive possibilities for efficient drug release at desired place and time.

Modulight’s solution with ML8500: Light-sensitive molecule indocyanine green was incorporated into liposome, releasing contents when illuminated with a laser light. Light-triggered release was studied by irradiating liposomes with ML8500 and was precisely controlled by strength and duration of the illumination.

ML8500 for hypoxia

Background: Hypoxia is a state in which oxygen is not available in sufficient amounts at the tissue level. In vitro study conditions should ideally resemble physiological conditions as closely as possible (e.g. tumor centers are often hypoxic)

Modulight solution with ML8500: ML8500 an incubation chamber optimized for hypoxic experiments. Hypoxia dynamics, optimal gas flow rate, and different oxygen concentrations were optimized to be used for drug studies with ML8500
