Bridged silsesquioxanes (BS) is a family of hybrid silicas which are obtained by the hydrolysis-condensation of silylated precursors with bridging organics, (EtO)3Si-R-Si(OEt)3 (R = organic fragments). Thanks to the mild sol-gel reaction conditions, the relatively strong covalent Si-C bonds are maintained during the reaction, resulting in the formation of unique hybrids, which consist of a uniform distribution with stoichiometric Si/C ratio of covalently bonded organics interconnecting at least two silicon atoms.
These hybrid organic-inorganic materials combine the inherent properties of the organic fragments with those of the silica network (mechanical and chemical stabilities as well as high surface area and porosity). Accordingly to the variety of organic units that can be introduced in BS, one can tune the properties of the final materials for targeted applications (e.g. catalysis, optics, magnetic and imaging, etc.). Moreover, these hybrids can be structured in mesoporous materials when synthesized with a surfactant. The resulting hybrid is called Periodic Mesoporous Organosilicas (PMO).
In this presentation, the design of selected BS precursors will be shown. The role of the organics for catalysis applications, the self-directed structuring as well as template-mediated structuring of these hybrids, called PMO6, will also be addressed. The synthesis of functional hybrid mesoporous and of nano-PMOs will be presented and their use as drug carriers will also be presented.
Michel WONG CHI MAN is a senior researcher at the French National Centre for Scientific Research (Centre National de la Researche Scientifique; CNRS). He is an expert in organosilicon and hybrid silica chemistry and has published over 160 articles in peer-reviewed journals in these fields. His main research interests focus on the functionalization of hybrid silica (mainly bridged silsesquioxanes), which he develops in several different areas: Nano-structuring of hybrid silicas; catalysis; photoluminescent materials; stimuli-responsive hybrid silica nanoparticles for drug delivery.

The Fraunhofer Project Centre for Biomedical Engineering and Advanced Manufacturing (FPC-BEAM) is hosting a workshop on the challenges of developing clinical diagnostics in specific fields and opportunities for POC diagnostics. The two-day workshop will bring together various stakeholders for presentations, panels and open forums to discuss the ideal POC diagnostic, POC development and the support systems needed to bring these diagnostic healthcare solutions to market.
The Project Manager will provide daily leadership, direction, and operational management for the ORF grant. This individual will also function in the capacity of alliance and business development manager, liaising with all parties involved in the project (i.e. industry partners, researchers, and the university partners) to ensure the team is well-functioning and will work with MILO to protect and license IP, and guide business development efforts.
The Project Manager will organize and prepare materials for meetings of the Board of Directors and all other committees, and will be responsible for and ensure the execution of the actions approved by these committees.

One of our BI members David Latulippe just had a paper from his group accepted for publication in Biotechnology and Bioengineering. We are very pleased to provide access to our micro plate reader and gel imaging systems which are used by David Latulippe and his group.
We would like to thank MP Mike Lake, for touring the IIDR and the Biointerfaces Institute.

This study has been motivated by a major obstacle in the use of glassy and ceramic materials as injectable biocompatible carriers: Despite the fact that the vast majority of oxide-based biomaterials studies have been carried out on silica, no major pharmaceutical company has 'raised the glove' to get the FDA and the other regulatory agencies approval for this material as an injectable carrier of therapeutical components.
McMaster students had a chance to discuss autism awareness and the concept of a national autism strategy with a federal MP last week.
Mike Lake, MP for Edmonton-Mill Woods-Beaumont, holds autism awareness close to his heart and has been an active supporter of autism organizations, families and individuals across the country, sharing his story of life with his son Jaden, who has autism.

Brandon Aubie just wanted to connect more researchers with McMaster's Biointerfaces Institute. He ended up creating a whole new company. The self-described "math geek turned neuroscientist" has created what might just be the Match.com of research equipment and expertise, and the site is now taking off across the country.
It’s an online ‘library’ for research equipment that first began in the Biointerfaces Institute (BI), McMaster’s – and Canada’s – premier research facility for developing unique surfaces at the interface of biology and materials. The BI is home to a vast array of high-tech equipment, machines and instrument suites in a shared environment designed to connect researchers and industrial users from multiple disciplines.
remarkable discovery by a team of researchers at the Biointerfaces Institute at McMaster University will enable people all over the world to determine in seconds if their water is safe. Dr. Carlos Filipe, lead researcher at the institute and chair of chemical engineering, and Sana Jahanshahi-Anbuhi, a Ph.D. student in chemical engineering, describe this breakthrough discovery and how the research-focused student-centred environment within McMaster Engineering inspires innovation that transforms the world.
After Brandon Aubie earned his PhD at McMaster University, he joined the university’s Biointerfaces Institute, which opened in 2013 with $22 million in funding from the Canada Foundation for Innovation, the provincial government and industry partners. “We had tons and tons of really cool equipment that we figured everybody would want to use,” he recalls. “But we had a lot of trouble getting people to come in to our facility to use it.” The reason, he says, is that few people outside of the institute knew the equipment existed.
Billions of dollars in taxpayer funded research equipment sits idle in university and college labs across Canada and the world. Simultaneously, many researchers and businesses are eager to utilize these resources and form new collaborations.

At first, minty-fresh breath strips vowed to transform the way people prepared for a make-out session. But researchers say that the sugary, flexible material is actually capable of far more. The same stuff we use to freshen our breath could soon be deployed to detect dangerous chemicals and bacteria in drinking water.

A pair of University researchers have received a $600,000 CIHR award to develop a bioactive paper that aims to provide an inexpensive, point-of-care diagnostic tool to measure bronchitis in patients with airway diseases, such as asthma, COPD and chronic cough.
Dr. Parameswaran Nair, associate professor, Medicine, holds the CIHR Canada Research Chair in Airway Inflammometry. Dr. John Brennan is a Canada Research Chair in Bioanalytical Chemistry, and director of McMaster's new BioInterfaces Institute. The research is supported by AllerGen NCE, a national network for asthma and allergic diseases research, headquartered at McMaster.
