ML7710 for photoactivated treatment of lung cancer

Deadliest cancer Precision with photoactivation Photoimmunotherapy with ML7710 offers a clinical therapeutic option for NSCLC patients even with advanced disease stage. Besides laser light, this therapy involves photoactivated drug, which can be activated precisely at the tumor site with laser fibers, hence minimizing drug effects to healthy tissues. Smaller invasiveness compared to surgery can enable patients to stay less time recovering at the hospital. It can also be repeated if needed multiple times without cumulating toxicities, unlike radiation therapy. Some previously inoperable tumors can decrease Continue reading →Deadliest cancer Lung cancer is the leading cause of cancer deaths worldwide, with more than 2.2 million cases and 1.8 million deaths each year [1]. Lung cancer can be divided into two types, small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), with the latter accounting for about 85% of all lung cancer cases. NSCL is usually less sensitive to chemo- and radiotherapy and in many cases tumor cannot be removed surgically or has spread from lungs to distant sites at the time 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.

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
