Modulight Spotlights: LASER-SHARP RESEARCH – February 2023

 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. Light is studied as an important tool to control the drug delivery to the target tissues.

Ophthalmic laser platform utilizing AI to enhance treatment planning of liposomal drug release

Presented in: SPIE BIOS 2022 Authors: Eero Koivumäki, Laura Vesala, Jukka-Pekka Alanko, Timo Tanila, Petteri Uusimaa, Modulight Corporation (Finland)    Presented in: SPIE BIOS 2022 Authors: Eero Koivumäki, Laura Vesala, Jukka-Pekka Alanko, Timo Tanila, Petteri Uusimaa, Modulight Corporation (Finland)   Delivery of pharmaceuticals to the eye posterior poses a major challenge in ophthalmology. A promising drug delivery platform is indocyanine green (ICG) liposomes, which absorb near-infrared light resulting in a release of pharmaceutical molecules. The Modulight ophthalmic laser platform has been designed for treatments targeting the eye posterior and can also excite the absorption band of the liposomes. The laser connects with Modulight Cloud, enabling Continue reading →

Modulight Spotlights: LASER-SHARP RESEARCH – October 2021

   Modulight Spotlights: LASER-SHARP RESEARCH – October 2021 This time we wanted to highlight Professor Tebello Nyokong’s team at Rhodes University, since their latest research tackles two big unmet needs in cancer therapy: tumor hypoxia and side effects of the drugs. The team designed multifunctional liposomes that can locally generate oxygen within tumors to alleviate hypoxia, which is a significant contributor to resistance to radio- and chemotherapies. These nanodrugs also hold the potential to reduce problematic side effects of standard cancer therapies as a result of Continue reading →
