Telescopic lens zooms with a wink

EPFL‘s Eric Tremblay and DARPA have developed contact lenses with integrated tiny telescopic lenses to boost vision. The lens is controlled by smart glasses that respond to the winking of an eye, and provides magnification of up to 2.8 times. This can be a visual aid for Age-related Macular Degeneration and other conditions, in addition to […]

DNA sensor detects cervical, bladder, kidney cancer

University of Twente MESA+ professor Wilfred van der Wiel is developing an electrode to detect cervical, bladder and kidney cancer in DNA. NanoGap is a 100 nanometer wide gap in a metal electrode with receptors that provide notifications when urine DNA is degraded.  Hypermethylated DNA is bound to the receptors.  By covering the DNA with metal particles, a live […]

Breath test to detect early stage lung cancer

University of Leicester and Owlstone Nanotech are developing a breath test to detect early stage lung cancer.  Clinical trials for the device will begin soon.  Last year ApplySci described a Cleveland Clinic developed sensor with a similar purpose.  The study is being led by Leicester’s Dr Salman Siddiqui. LuCID (Lung Cancer Indicator Detection), based on Owlstone’s GC-FAIMS (Gas […]

Smart bandage continuously measures pH and oxygen

Harvard professor Ali Khademhosseini, a doctor at Brigham and Women’s Hospital, is developing a smart bandage that determines a wound’s healing progress and distributes medicine accordingly. The prototype bandage looks like rubber, and has visible sensors tracking pH balance (for bacterial infection), and oxygen, automatically delivering oxygen or antibiotics topically.  Diabetic foot ulcers might be better treated this […]
