 Modulight Spotlights: LASER-SHARP RESEARCH – February 2023 The nomination for Laser-Sharp Research goes to Mäki-Mikola et al. at University of Helsinki for their development of a dynamic cell culturing platform for light-activation studies. The developed platform has a flow chamber connected to a peristaltic pump, which creates a flow that resembles the natural fluid flow at the cell surfaces. ML6500 laser was used to release calcein from liposomes to validate the suitability of the platform for light-triggered drug release. Compared to traditional static cell culture Continue reading →

Light-induced drug delivery with indocyanine green liposomes

Introduction to light-controlled drug delivery systems Study description It is important that light-triggered liposomes efficiently release their contents, while the liposome stability should be maintained in the absence of laser light. The aim of this study is to determine how liposomal stability and drug release are affected by liposomal formulation. Indocyanine green was used as the light-sensitizing compound in the liposomes since it is clinically approved light-sensitive agent. Three different liposomal formulations were prepared: Formulation A: ICG in the aqueous core, liposomes coated Formulation B: ICG in the liposomal Continue reading →Customer case Faculty of Pharmacy at University of Helsinki is specialized in top-level pharmaceutical research. Multidisciplinary research fields include clinical pharmacy, experimental drugs, nanomedicines, and pharmaceutical drug design. Drug delivery unit led by Professor Arto Urtti focuses on design and testing of advanced drug delivery systems especially for ocular indications.

 Modulight Spotlights: LASER-SHARP RESEARCH – August 2022 Impressive research on head & neck cancer was published by Obaid Lab for molecular imaging and optical nanotherapeutics, at University of Texas, Dallas. The group used Modulight’s ML6500 for a subtherapeutic modulation of tumor microenvironment of H&N. This significantly improved delivery of molecular imaging agent to the tumors as well as improved diagnostic accuracy in detecting tumor tissue by fluorescence. Since incomplete resection and consequent recurrences are common problem with current H&N cancer treatment, this discovery answers unmet Continue reading →

 Modulight Spotlights: LASER-SHARP RESEARCH – July 2022 Modulight congratulates Dr. Makoto Mitsunaga et al. Jikei University School of Medicine for publishing their promising results in Communications Biology journal. The team developed a next-generation light-based approach to tackle pathogens, called photoimmuno-antimicrobial strategy (PIAS). This technology was shown to eliminate a broad spectrum of different classes of pathogens, such as viruses, fungi, and bacteria. Unlike antibiotics, PIAS was also effective against drug-resistant pathogens and didn’t damage natural, beneficial microbiota in the host’s tissues. As COVID-19 pandemic and Continue reading →

   Modulight Spotlights: LASER-SHARP RESEARCH – February 2022 Photocure’s blue light cystoscopy is a routine procedure in the management of bladder cancer as it results in better tumor visualization and removal. However, this study found that the positive effects of blue light cystoscopy could extend beyond visualization and result in the induction of systemic antitumor immunity, which can be further boosted with immune checkpoint inhibitors. Modulight nominated this study because bladder cancer is highly recurring and progressive disease with more than 200,000 deaths worldwide annually. Thus, Continue reading →

Light delivery optimization for H&N cancer treatment

Results Illumination with one fiber Some level of tissue heating was observed at all used light intensities. At lower intensities (60-100 mW/cm), less than 5% of the tumor was subjected to >60 ⁰C temperature, a point where irreversible thermal damage will immediately occur (photothermal ablation). At intensities of 150-200 mW/cm, 15-20% of the tumor was at >60 ⁰C temperature. At 400 mW/cm, which is FDA-recommended light irradiance for iPDT, a substantial portion of the tumor, up to 60%, was above 60 ⁰C.   Above figures Continue reading →Customer case Roswell Park Comprehensive Cancer Center was founded in 1898 as the first institute in the US devoted exclusively to cancer treatment and research. It is also the place where photodynamic therapy (PDT) was developed in the late 1970s by Thomas Dougherty. The PDT center at Roswell Park is a leader in the use of photodynamic therapy for treating different cancers. Research work includes treatment planning and light dosimetry for interstitial and intraoperative PDT to improve the quality of life and survival of cancer patients Continue reading →

Protected: New approach for targeted PDT of glioblastoma

There is no excerpt because this is a protected post.Customer case Research in close collaboration with University Medical Center Utrecht, Erasmus Medical Center and Leiden University Medical Center. Research focused on the efficacy and mechanisms of targeted cancer photoimmunotherapy using nanobodies (antibody fragments). The advantage of nanobodies lies in the combination of their small molecular size, with high binding affinity for their targets, resulting to high accumulation at the tumor site, better tumor penetration and faster clearance from blood circulation. The aim is to target therapy to cancer cell-expressing antigens like EGFR (H&N cancer) Continue reading →

      Results PIAS-treated pathogens were effectively eradicated upon NIR illumination. The efficacy of PIAS was dependent on the NIR light dose, 50 J/cm2 eradicating all MRSA from the rat nasal tract (Figure 1). PIAS also saved all mice from fatal MRSA infections, similar to VCM+RFP antibiotics and even more effectively than VCM antibiotics alone (Figure 2). Unlike the antibiotics, PIAS acted selectively on the target pathogen and did not affect host’s normal intestinal microflora (Figure 3). Also generation of microbial resistance, common problem Continue reading →Customer case Research by: The Jikei University School of Medicine located in Tokyo, Japan and founded in 1881 is today one of the three major private medical schools in Japan.
