U of T researchers demonstrate new class of solar-sensitive nanoparticle

University of TorontoNew research emerging from the University of Toronto’s Edward S Rogers Sr. Department of Electrical and Computer Engineering is developing and demonstrating a new class of solar-sensitive nanoparticle.

MaRS Innovation is working with Professor Ted Sargent, his research team and U of T’s Innovations and Partnerships Office (IPO) to incubate and commercialize this and other solar technologies. Their work was recently published in Nature Materials.

The paper’s publication was widely covered in the technical trades, including CNET.com, Tech Times, Compound Semiconductor.net and Gizmag, among others, and on the university’s website.

Here’s an excerpt from power-technology.com:

Led by post-doctoral researcher Zhijun Ning and Professor Ted Sargent, the research work resulted in the development of a new form of solid, stable light-sensitive nanoparticles, known as colloidal quantum dots.

Developed in collaboration with Dalhousie University, King Abdullah University of Science and Technology and Huazhong University of Science and Technology, the solar-sensitive nanoparticles are cheaper than the traditional panels, large and rectangular.

In addition to being cheaper, the colloidal quantum dots are more flexible solar cells, and better gas sensors, infrared lasers, infrared light emitting diodes and more.

Cellax profiled in SciBX; MaRS Innovation’s MSc PoP program cited in National Post supplement

CellaxThe Cellax technology was profiled in a recent issue of  SciBX (subscription necessary). MaRS Innovation is mentioned in the article as the technology’s commercialization agent.

Here’s an excerpt:

Ontario Institute for Cancer Research scientists have developed glycopolymer-conjugated docetaxel nanoparticles that outperform Abraxane in mouse models of breast cancer. The Ontario Institute for Cancer Research (OICR) is backing the program with $1.5 million to take it to the clinic. The expectation is that the product’s ability to target the tumor stroma rather than the tumor itself will differentiate it from Abraxane and other chemotherapeutic formulations.”

DLVR: Using personalized medicine and nature’s cellular toolkit to target cancer tumours

Every six weeks, MaRS Innovation’s marketing and communications manager writes a guest post for the MaRS Discovery District blog profiling MI’s activities or one of our start-up companies. This post coincided with World Cancer Day.

DLVR TherapeuticsWhat if you could use a cancer tumour’s proteomic profile to make it easier to target and destroy?

Targeting specific proteins on the surface of individual tumours—or, more precisely, targeting a cell receptor that naturally allows substances to pass into a cell—would allow clinicians to more effectively deliver drugs designed to deactivate cancer-promoting genes within the tumour, while minimizing the addition of toxins to the patient’s body.

Personalized medicine research in Toronto also benefited from a recent  $50 million donation to support Princess Margaret Hospital (part of the University Health Network). Read and watch the news announcement on BioTechnology Focus.

This is personalized medicine’s promise for cancer treatment: targeted therapies that stand a better chance of success, with reduced side effects, based on the unique profile of a patient’s tumour, either administered on their own or in combination with traditional chemotherapy.

OICR and MaRS Innovation announce funding to develop Cellax™, a nanotechnology-based cancer drug

CellaxTORONTO, ON (November 13, 2012) — The Ontario Institute for Cancer Research (OICR) and MaRS Innovation (MI) today announced $1.5 million in funding from OICR over three years to further develop Cellax, a nanoparticle drug that could offer an alternative to chemotherapy with fewer side effects.

“Cellax is promising because it provides a more targeted strategy for treating tumours, killing tumour cells while minimizing the effect on healthy tissue,” said Dr. Rima Al-awar, director, OICR’s Medicinal Chemistry Platform. “OICR is proud to invest in a technology that has such potential to one day improve quality of life for cancer patients.”

Cellax, invented by Dr. Shyh-Dar Li and his research team in OICR’s Medicinal Chemistry Platform group, is a drug-polymer conjugate based on Dr. Li’s proprietary NanoCMC™ technology. These polymers self-assemble into defined nanoparticles and, when injected, selectively accumulate in tumours. Because of this property, the drug is released where it is most needed, increasing therapeutic benefits and reducing the side effects associated with conventional chemotherapy.

Physicist pairs with pharmaceutical scientist to design nano-particles for cancer imaging

TORONTO (November 19, 2009) – In the drive to improve early detection and treatment of cancer, a pair of Toronto scientists has developed a unique technology that combines contrast agents with targeted, long-lasting nano-particles for use in multiple medical imaging platforms.

While contrast agents are routinely injected into patients to enhance the quality of medical images, different agents are currently required for various imaging modes (e.g. MRI, CT, PET) each with inherent strengths and limitations. By combining more than one contrast agent into a nano-particle for use in multiple types of imaging, not only are physicians and researchers able to use lower doses of contrast agents (with lower toxicity) but the nano-particle also enables targeted delivery to, and retention by, specific tumours.
