This New Smartphone-Based DNA Test Could Help Track Disease in Real Time

Posted by in categories: 3D printing, biotech/medical, computing, mobile phones

Scientists typically use a method known as polymerase chain reaction (PCR), but it requires bulky and expensive equipment and considerable expertise to perform correctly. That means DNA samples collected in the field normally have to be sent to dedicated laboratories for testing, which makes it hard to detect diseases or harmful pathogens quickly.

A new testing system developed by researchers at the Army Medical University in China may help to fill that gap by allowing on-the-spot DNA tests in as quick as 80 minutes. According to the researchers, their test achieves 97 percent accuracy using simple 3D printed parts that attach to a standard smartphone and weigh less than 100 g rams (0.22 pounds).

At the heart of the system is an “i-chip” just four centimeters long that includes integrated sample preparation, DNA amplification, and signal detection modules. The various reagents required to carry out the test can be pre-loaded in the device, and the researchers showed that these could be kept for up to ten weeks at room temperature without loss of performance.

Pocket-sized device tests DNA in blood samples for genetic conditions

Posted by in categories: 3D printing, biotech/medical, genetics, mobile phones

It is now possible to use a cheap, lightweight and smartphone-powered DNA detector to identify DNA in blood, urine and other samples, on the spot.

At the moment, testing to identify DNA is usually done in laboratories using expensive, specialised equipment. To make this process faster and cheaper, Ming Chen at the Army Medical University in China and his colleagues developed a portable DNA detector made of 3D-printed parts that attach to a standard smartphone.

Why DIY 3D-Printed Face Masks and Shields Are So Risky

Posted by in categories: 3D printing, biotech/medical, education, government

An interesting cautionary note on the well-intentioned effort to supply personal protective equipment (PPE), such as masks, via 3D printing. I’ll confess that I have not thought through all the implications.


“One of the hospitals calls it ‘the garage PPE,’” said Sarah Boisvert, founder of 3D-printing school Fab Lab Hub, who works with hospitals to 3D-print materials. “This is a far more complicated problem than just making Christmas ornaments for your family.”

Lovett readily admits that he is not an expert. But he and others who want to help are stymied in part by a lack of clear government regulation around simple designs.

Coronavirus: snorkling mask becomes ventilator

Posted by in categories: 3D printing, biotech/medical

Charlotte Valve to convert snorkeling mask into ventilator, 3D print guide available for free on their website, approved by the EU for widespread use, and is already being used in Italy.

I’m not an expert or a doctor or a mechanical engineer. I share this with the best of intentions. If you have any questions, I hope someone else can expand on that for you.

Best of luck to all of us.

Indian Army has disinfectant drone, UV gun that kills virus in seconds in its Covid arsenal

Posted by in categories: 3D printing, biotech/medical, computing, drones

The cost of the sanitiser would be Rs 800, and the Army can turn out 10 pieces a day.

The third innovation is a 3D-printed mask priced at Rs 1,200 apiece. Other products being devised include thermal scanners and anti-aerosalination boxes to keep doctors safe. The boxes are made up of transparent acrylic sheets and kept over patients to protect doctors and other healthcare workers from infection. Holes cut into the box help medical staff administer treatment to the patient without coming into direct contact.

The Army is just one of several sections across Indian society that are trying to chip in for the country’s battle against coronavirus, from scientists who have banded together to bust myths to IITians churning out cost-effective and innovative solutions to ease the burden on the healthcare framework.

Speedy 3D Printer Could Revive Algae Biofuel, With Coral Bonus

Posted by in categories: 3D printing, sustainability, transportation

Algae biofuel certainly faces an uphill battle these days, what with the global oil price crash and competition from electric vehicles. Nevertheless, there may be a glimmer of hope for algae biofuel fans, in the form of an ultra-fast 3D printer housed in a California laboratory. In an interesting sustainability twofer, the same machine might also spit out an assist for the world’s ailing coral reefs.
