Health, technological innovations (part two)

Here is the second part of the article on the latest technological innovations that come from the world of Health. In this part we talk about a new common language for magnetic resonance imaging, really special contact lenses and a new microscopy technique.

Contact lenses measuring Glucose, lactic acid, Ph and release drugs

Researchers at Purdue University have developed soft contact lenses that not only correct vision, but can also monitor glucose, medical conditions and be used for the relief of eye pain or medication delivery.

In the past it was not possible to use sensors or other soft contact lens technologies because the technology required a rigid planar surface incompatible with the soft, curved shape of a contact lens.

The Purdue University team, led by Chi Hwan Lee, an assistant professor of biomedical engineering and mechanical engineering, has created a new method to connect sensors and other small soft contact lens devices.

Sensors embedded in the soft contact lens detect glucose, lactic acid levels and pH values ​​continuously, providing information associated with diabetes, hypoxia and underlying ocular tissue health. Thanks to the possibility of combining silicon-based soft contact lenses with a variety of devices, many advanced eye care applications are now possible.

Monitor of the wearable vital signs for newborns

Neopenda, a Chicago-based medical device startup, is developing medical solutions for low-energy resources and has recently unveiled its first product, a wearable vital sign monitor for newborns. The company reported that nearly 3 million children die within the first month of life. Up to 98% of these deaths occur in developing countries and in many cases these deaths are preventable.

In some of these countries a lack of resources can lead to insufficient staff and health facilities. This means that it is difficult or impossible for healthcare personnel to monitor sick infants adequately to assess if they are in need and need treatment. To solve this problem, Neopenda has developed a wearable baby monitor that can continuously monitor vital signs such as heart rate, blood oxygen saturation and temperature. The device can then transmit this information via Bluetooth and an app

displays vital signs in an accessible format, highlighting if there are any potential health problems.


A common electronic language for magnetic resonance imaging

A group of chemists led by UNIGE (University of Geneva) has just created a common electronic language to share organic chemistry data with the entire international scientific community.

Scientists working in the field of organic chemistry have always been looking for new molecules that are created and studied using magnetic resonance. The standards used to re-transcribe the collected data are however specific to each laboratory or publication, making it difficult to electronically export the information and therefore use it by the scientific community. An international team led by chemists from the University of Geneva (UNIGE) has developed a new common electronic language around two main characteristics: it translates the data of each molecule in exactly the same way and simplifies the export from one information system to another. This means that chemists from all over the world can easily access data, which are also directly reusable, resulting in significant time savings for future research.

This study, published in the journal Magnetic Resonance in Chemistry (Wiley), paves the way for the creation of an international database with open access and specific tools, including the analysis of artificial intelligence.
The idea of ​​a common electronic language is closely linked to the desire to create a database with free access. This would allow chemists to find the exact composition of the molecules they are studying without having to redo the work that has already been done in the past, the information will be visible and available anywhere and at any time, saving time and money for research on organic chemistry.

New microscopy technique, visualize tissue images in real time

University of Illinois researchers have developed a new microscopy technique that can visualize living tissues in real time, without the need for dyes. The technique can obtain significant details, such as allowing researchers to see the movement of the vesicles, between cells. This approach could be used during surgical procedures to evaluate tissues of interest and has significant potential in tissue pathology, diagnostics and disease monitoring applications.

The system uses light pulses at different wavelengths to simultaneously visualize different tissue characteristics, the researchers called it "simultaneous label-free autofluorescence multi-harmonic microscopy" (SLAM). "Researchers are currently developing a portable version of the device.
