McMaster University has developed a process whereby ordinary inkjet printers can be given a special cartridge containing DNA-based bio-ink that produces paper sensors patterned after the codenames of pathogens.
Sensors that identify infectious disease and food contaminants may soon be printed on paper using ordinary office inkjet printers. Researchers at McMaster University have developed a prototype that could lead to a commercial product in the next few years which helps doctors and scientists in the field quickly detect certain types of cancer or bacterial and respiratory infections or monitor toxin levels in water.
“In the published paper, we detect ATP (adenosine triphosphate), which is a marker of bacterial contamination, and PDGF (platelet derived growth factor), which is a marker for cancer,” Brennan explained. “We can print the letter ‘A’ for ATP and ‘P’ for PDGF, so that the letter encodes the compound detected. This allows us to do something we call multiplexing, where we can use any combination of letters or symbols to allow detection of many different targets on a single test strip.”
Just think of the applications for this product, they are far reaching and would save many lives in developing world countries.
Do you have the expertise to save lives by developing advanced detection tools for the medical field?
Travel can be risky – monetary crises, allergies to unusual foods, unsafe drinking water…and being a potential robbery target as you navigate unfamiliar locales. Not that I’m advocating fear of traveling! I love to go exploring anywhere and everywhere. Sometimes, just getting there carries risks, too.

With global concern about the spread of diseases, this young man’s invention may make the air we breathe safer for everyone – and it has applications far beyond commercial flights. What adaptations can you envision?
Freedom includes the right to go where one wishes – unfettered and unafraid. At least, that’s the concept… When one is hampered by a physical impairment, travel becomes more challenging. A short walk can become nightmarish when you are unable to clearly see the dangers that lie in your path.
Read about Alex Deans, and his prize-winning invention. On June 2nd, he received the 2015 Weston Youth Innovation Award from The Ontario Science Centre. At age 12, he identified a need to be met and worked on his own to acquire the skills and knowledge to address it.
He’s now 18, and the end result is:
Providing assistance for the visually impaired, the system works like a GPS, using ultrasonic sensors and smartphone technology to help in navigation for a human rather than a car. To take on a project that was wholly altruistic in nature is truly remarkable. Although the product is not yet available on the market, it is on its way. And I, for one, am confident that Alex has more in store for us in the future!
Infant mortality was a serious concern in almost every country during centuries and decades gone by. While medical technology in developed countries has radically reduced the rate of infant deaths in a great many places, in developing countries, it remains a serious problem. Take a look at a proposed affordable medical technology, developed by seniors at Rice University (in Houston, TX in the United States), which they have designed to address the situation…

Neonatal hypothermia, a condition in which an infant’s core body temperature is less than 35C, is a dangerous health condition that often compounds illnesses and may lead to death. In the developing world, access to affordable, effective incubators is limited. Our project is to develop an innovative, low-cost neonatal incubator for the developing world that focuses specifically on temperature feedback and safety.
There are many funding opportunities available to those who are interested in exploring the pathways of the entrepreneur. Here’s one to take a look at…
Here’s their newest challenge: StartEdu 3 Application Opens on July 1, 2015. The StartEdu Competition is a nationwide program looking to identify, mentor, incubate, and invest in the most promising early-stage education startups that are serving India’s masses.
From the B. V. Bhoomaraddi College of Engineering & Technology website
“LabInApp, a CTIE start-up, participated in a competition called StartEdu by Unitus Seed Fund. LabInApp got short-listed in top 11 educational start-ups across India. Many of these startups are from IITs and IIMs !! In the end, LabInApp (previously Intuitive Labs) has won the StartEdu competition. And now eligible for one crore investment.”
