CORNELL (US) — Researchers are developing a small detector designed to quickly identify pathogens such as tuberculosis, chlamydia, gonorrhea, and HIV.

Dan Luo, professor of biological and environmental engineering at Cornell University, has devised a method of “amplifying” very small samples of pathogen DNA, RNA, or proteins using synthetic DNA. His colleague Edwin Kan, professor of electrical and computer engineering, designed a computer chip that quickly responds to the amplified samples targeted by Luo’s method.

The researchers will combine the two to make a portable device that can be used in harsh field conditions and report in 30 minutes what would ordinarily require transporting samples to a laboratory and waiting days for results.

Luo’s research group has found that DNA can be used like molecular-level Lego blocks. A single strand of DNA will lock onto another single strand that has a complementary genetic code. By synthesizing DNA strands that match over just part of their length, his team can assemble unusual shapes, in this case a Y. Attached to the base of the Y is a DNA strand or antibody designed to lock onto a pathogen. Attached to one of the upper arms is a molecule that will polymerize—chain up with other similar molecules—when exposed to ultraviolet light.

When a pathogen is added to a solution of these Y-DNA molecules, the matching receptors on the stem of the Y will lock onto pathogen molecules, but only onto part of them; the mix will contain two different Y-structures, each tagged to lock onto a different part of the pathogen molecule. The result, when the targeted pathogen is present, is the formation of many double-Ys linked together by a pathogen molecule, each assembly carrying two molecules capable of polymerizing.

When the mixture is exposed to a portable ultraviolet light, the polymer molecules at the ends of each double-Y link to those on other double-Ys, forming long chains that clump up into larger masses. This polymerization won’t happen, the researchers emphasize, unless a targeted pathogen is present to link two Ys together. A single Y with only one polymer molecule attached can only link to one other single Y, and no chain will form.

Kan’s new chip measures both the mass and charge of molecules that fall on it. The large clumps of Y-DNA have a much larger mass and charge than single molecules, and trigger the detector. The chip uses the popular and inexpensive CMOS technology compatible with other common electronic devices. A detector might, for example, be controlled and powered by a mobile phone, Luo suggests.

All this can be combined with nanofluidics to make a robust battery-operated testing kit, the researchers say. After further development they plan to conduct tests simulating field conditions in the developing world. Along with surviving hot or cold weather, Luo says, “It has to work in dirty water.”

The work will be supported by the Bill & Melinda Gates Foundation as part of the Grand Challenge program to develop “point-of-care diagnostics” for developing countries. The foundation has distributed $25 million to 12 teams, selected from more than 700 applicants. Various teams are working on different aspects of the technology, and eventually their work will be integrated to make a practical, low-cost testing kit, Luo says.

Best Handheld Ultrasound Devices Compared

Handheld ultrasound device is the future of all USG scanners. No wires, no more clutters. These devices are so user friendly, cozy and portable that any radiologist can hardly resist from getting one. We compare the best of them available in today.

1 Clarius Wireless Handheld Ultrasound Device

Clarius manufactures one of the most advanced handheld ultrasound device, which wirelessly streams data to most iOS and Android devices. You can see view live view on your iPad or Android screen with the help of a simple app. There is a cloud storage option also, and a digital library is just a touch away.

It has passed recently CE Mark approval for the commercial sale of the C3 and L7 Clarius Wireless Ultrasound Scanners for use by medical professionals. C3 Scanner is capable of multipurpose scanning of all parts of the patient’s torso, including the heart. The devices exhibit outstanding resolution with its convex array for abdominal and lung images. L7 is Linear Array Ultrasound Scanner and ideal for guiding procedures. Easy to sterilize and keep clean. One can easily get fine detail from 1 to 7 cms from L7. Both the devices come with full body metal jacket which gives a premium look. These devices have 45 minutes of active battery life and 7 plus hrs standby time.

2 Philips Lumify App Based Handheld Ultrasound Device

58af26c37cedb_philipshandheldultrasound.PNG.3493f3292c24bb55f939d7e8aaa81acf.PNG

Phillips Lumify handheld ultrasound probes are time tested device and connects to your tab or smartphone with a micro USB port. Its got a simple interface to manipulate and requires just an installation of the Lumify App. Lumify goes where you go, so you can start scanning without searching for equipment in the emergency department. It looks more or less like a standard ultrasound probe with a micro USB on the far end. Lumify doesn't need to be charged. Once connected, It is powered by your Android device. The Lumify app enables users to store scans, images and has the ability to share via email. It also has cloud based storage ability. The app only recognizes Lumify probes, and during first set up device registration is required. Unfortunately Lumify doesn't support iOS.

Lumify has three types of probes, S4-1, L12-4 and C5-2. Lumify S4-1 is suitable for Lung, Echo, Abdomen, Ob Gynae and FAST. Lumify L12-4 is meant for soft tissue, superficial, MSK and Vascular in addition to Lungs.

3 Fujifilms Sonosite iViz Handheld Ultrasound Device

58b0571c15df4_MobileUltrasoundDevice.jpg.be601d1cdad112a340fcd7e3a56a23b1.jpg

Unlike Claurius and Lumify, Fujifilm Sonosite is not compatible to Tab or Smartphones via apps. It comes with a 7 inch display system. The high-resolution touch screen and innovative thumb operated user interface helps the doctor quickly go through various modes and enables quick diagnosis. iViz supports a range of clinical applications, interchangeable transducers, and optimization controls allowing accurate assessment. The display unit can be easily held on left hand enabling the user operate with his thumb, while his right hand scans through the transducer.

Integrated Wi-Fi and Bluetooth connectivity allows iViz to connect to Hospital Medical IT Systems, Cloud Solutions or Patient Vital Sensors. There is a remotely diagnosing capability via secure cloud-based telemedicine solutions where patient information can be accessed iViz and send reports to the EMR, Other connectivity like Micro USB, HDMI ports, and audio ports allow iViz fully compatible to any other medical Info systems.
