The Purdue researchers developed an electronic chip that can read signals from several nerve endings and wirelessly transmit them without needing a battery or any other component. Energy is created by an on-chip antenna simil...
Device detects mosquito-borne diseases
A startup created by Purdue University professors is developing a sensor that can detect dangerous mosquito-borne tropical diseases faster and at a lower cost than current methods, giving health officials time to take action before the viruses are transmitted to humans. SMK Diagnostics has created biosensor technology to identify and monitor diseases such as Zika, which set off a global health crisis in 2015 and 2016, and dengue, which cause...
Soft contact lenses to monitor glucose and deliver medications
Purdue University researchers have developed soft contact lenses that not only correct vision but also can monitor glucose and medical conditions and be used for ocular pain relief or drug delivery. Sensors or other technology previously couldn’t be used for soft contact lenses because the technology required a rigid, planar surface incompatible with the soft, curved shape of a contact lens.
Solving America’s medication adherence epidemic
A Purdue-affiliated startup is developing a low-cost, high-tech solution to address the nationwide health crisis of Americans failing to take their medicine as prescribed. The Internet of Things system reminds patients to take medications and quickly alerts caregivers or providers when intervention is needed.
A safer approach to sterilising medical tools
Purdue University researchers have developed a device that uses cold plasma technology that could transform how medical tools are sterilised. The device generates cold plasma, which has high potential to be used in the fields of sterilisation and disinfection, through pure direct current high voltage instead of the conventional radio frequency or pulsed DC power.
Minimally invasive method could better treat cancer
Purdue University researchers have developed a minimally invasive technique that may help doctors better explore and treat cancerous cells, tissues and tumours without affecting nearby healthy cells. The method, called PLASMAT - Plasma Technologies for a Healthier Tomorrow - combines three emerging techniques that appear promising in the fight against most types of cancer.
Technology could help pregnant women detect health complications
Purdue University researchers are developing an app and wearable technology to enable pregnant women to use a smartphone to detect whether they have or are susceptible to a condition that could lead to serious health complications for them or their unborn child. The team, led by Craig Goergen, an assistant professor in Purdue’s Weldon School of Biomedical Engineering, is developing a low-cost automated early detection sensor of preecla...
Smartphones turn into detectors for foodborne illnesses
Purdue University researchers have developed detection technology that allows a typical smartphone to analyse produce for foodborne pathogens such as E. coli O157:H7, which has been linked to a deadly outbreak in romaine lettuce. The technology involves both hardware – a smartphone cradle – and software in the form of an application that is downloaded on the phone. The combination allows the smartphone to be used as an on-site lu...
Far-red fluorescent silk can kill harmful bacteria
A silk hybrid material attacks bacteria when illuminated by a green light, thanks to a far-red fluorescent protein researchers transferred to its genetic makeup. The all-natural material would be safer than conventional photocatalytic, or light-activated, means to kill harmful pathogens such as bacteria, which use potentially biohazardous semiconductors and require cancer-causing ultraviolet light for activation.
Model provides better understanding of cancer spread
Purdue researcher Luis Solorio has helped create a lifelike cancer environment out of polymer to better predict how drugs might stop its course. Previous research has shown that most cancer deaths happen because of how it spreads, or metastasises, in the body. A major hurdle for treating cancer is not being able to experiment with metastasis itself and knock out what it needs to spread.
'Quantum material''s shark-like ability to detect electrical signals
A 'quantum material' that mimics a shark's ability to detect the minute electric fields of small prey has been shown to perform well in ocean-like conditions, with potential applications from defense to marine biology. The material maintains its functional stability and does not corrode after being immersed in saltwater, a prerequisite for ocean sensing. Surprisingly, it also functions well in the cold, ambient temperatures typical of seawat...
Deep learning helps detect cracks in nuclear reactors
A system under development at Purdue University uses artificial intelligence to detect cracks captured in videos of nuclear reactors and represents a future inspection technology to help reduce accidents and maintenance costs.
