Microchips’ Programmable Drug Delivery Technology

microchips' technology is based on proprietary reservoir arrays that are used to store and protect potent drugs within the body for long periods of time. These arrays are designed for compatibility with preprogrammed microprocessors, wireless telemetry, or sensor feedback loops to provide active control. Individual device reservoirs can be opened on demand or on a predetermined schedule to precisely control drug release or sensor activation.


MicroCHIPS Technology


Our reservoir-based platform can also be used in passive control systems without microprocessors or power sources. microchips' passive systems are designed to release or expose their contents based on the controlled degradation of polymeric matrices over time. These systems form the basis for miniature insertable devices that provide maximum flexibility for device placement.

Intellectual Property
Our intellectual property portfolio supports our platform technologies and commercial products in development with approximately 140 issued or pending patents. These patents range from microreservoir fabrication and control, to long-term implantable technologies and wireless communications, as well as protein and peptide formulations for challenging delivery conditions.

'Remote control contraceptive chip available by 2018'

 

Chip from MicrochipsThe chip would need replacing every 16 years (chip pictured is not the one described in the article)

A contraceptive computer chip that can be controlled by remote control has been developed in Massachusetts.

The chip is implanted under a woman's skin, releasing a small dose of levonorgestrel, a hormone.

This will happen every day for 16 years, but can be stopped at any time by using a wireless remote control.

The project has been backed by Bill Gates, and will be submitted for pre-clinical testing in the US next year - and possibly go on sale by 2018.

The device measures 20mm x 20mm x 7mm and will be "competitively priced", its creators said.

Convenience factor

Tiny reservoirs of the hormone are stored on a 1.5cm-wide microchip within the device.

A small electric charge melts an ultra-thin seal around the levonorgestrel, releasing the 30 microgram dose into the body.

There are other types of contraceptive implant available, the researchers noted, but all require a trip to a clinic and an outpatient procedure in order to be deactivated.

Someone across the room cannot re-programme your implant” - Dr Robert Farra

"The ability to turn the device on and off provides a certain convenience factor for those who are planning their family," said Dr Robert Farra from MIT.

The next challenge for the team is to ensure the absolute security of the device to prevent activation or deactivation by another person without the woman's knowledge.

"Communication with the implant has to occur at skin contact level distance," said Dr Farra.

"Someone across the room cannot re-programme your implant.

"Then we have secure encryption. That prevents someone from trying to interpret or intervene between the communications."

Huge range

The same technology could be used to administer other drugs.

Simon Karger, head of the surgical and interventional business at Cambridge Consultants, said that implanted technology like this faces a range of challenges and risks.

But he added that overall "the value to the patient of these types of implant can be huge and we foresee a future in which a huge range of conditions are treated through smart implanted systems".

Implanted devices could help people who forget to take medication at the correct time

The innovation comes at a time when governments and organisations around the world have agreed to try to bring family planning to around 120 million more women by 2020.

This challenge opens the door to this kind of implant technology being used in areas where access to traditional contraceptives is limited - a bigger priority, argued Gavin Corley, a biomedical engineer.

The ISS HD Earth Viewing Experiment

One of the latest missions from the ISS is kind of amazing. The High Definition Earth Viewing (HDEV) experiment consists of four cameras that have been attached outside of the ISS. Though temperature is controlled, the cameras are exposed to the radiation from the sun, which will allow astronauts to understand how radiation affects the instruments.

The experiment is being run in conjunction with High Schools United with NASA to Create Hardware (HUNCH) program that serves as outreach for students 9-12. Students participating in this program also helped design some aspects of the camera.

The cameras point down at Earth at all times, which makes for some breathtaking images. The feed will sometimes go down as the signal switches between the cameras, and it is hard to see when the ISS is on the dark side of the planet. If the cameras are down, the screen will be grey.

Watch the live stream here:

If the feed is down, feel free to take a look at some of the “best of” footage taken by the cameras so far:
