WVU biomedical engineer receives $1.2 million to improve early detection of tick-borne infections

A group led by a West Virginia College biomedical engineer is working to ramp up and reimagine how medical professionals diagnose tick-borne infections similar to Lyme illness.
Soumya Srivastava, assistant professor on the Benjamin M. Statler Faculty of Engineering and Mineral Sources, is growing a device that extra rapidly detects tick-borne ailments by way of a blood pattern on a single chip. Srivastava’s mannequin goals to detect illness inside one to 2 weeks after the onset of an an infection, whereas current approaches depend on a symptom-based questionnaire – which could ask if an individual has a fever or a rash – and assessments that are not dependable till no less than a number of weeks after an infection.
Srivastava’s undertaking was just lately awarded $1.2 million as a joint initiative between the Nationwide Science Basis and the Nationwide Institutes of Well being.
Tick-borne pathogens could be handed to people by the chunk of contaminated ticks. These ticks can carry micro organism, viruses or parasites. Srivastava’s efforts might produce a much-needed device within the struggle in opposition to tick-borne diseases, which have ballooned in recent times. Lyme illness instances now hover round 30,000 a yr within the U.S., up from 22,000 in 2010, in response to the Facilities for Illness Management and Prevention.
Tick-borne illness can result in severe morbidity and mortality, and it has elevated considerably within the final 15-20 years within the U.S. This undertaking will create a fast, delicate and label-free diagnostic device to enhance early detection and their co-infections so as to scale back problems and loss of life from undiagnosed and late-diagnosed illness.”

Srivastava’s analysis will contain cross-disciplinary use of microfluidics, sensors and machine-learning. These elements will allow improved analysis of tick-borne infections by way of a non-invasive, reasonably priced, fast and user-friendly device.
After accumulating a blood pattern from a affected person, the device will analyze the cells. All cells have a set of dielectric properties like permittivity and conductivity which can be distinctive for cell membrane and cell cytoplasm, Srivastava defined. These properties are closely depending on the state of the cell, similar to whether or not it’s regular or irregular.
The distinctive properties rely upon the form and dimension of the cell; if the membrane is tough, clean or leaky; and what’s occurring inside the cell inside.
“We mainly are measuring these properties on our microfluidic chip,” she mentioned, “and {the electrical} sign coming from the sensor will assist us decide if there’s an an infection or not. This system is named dielectrophoresis.”
As soon as a number of drops of blood enter the gadget, an electrical subject will type them based mostly on the state, dimension and form of the cells. The sorted cells could have a baseline worth of capacitance that may present up by the sensor and thus we are able to conclude the kind of an infection, Srivastava mentioned.
“Machine-learning is utilized to make this device sturdy and delicate to detect a number of an infection inside couple of minutes.”
What makes the undertaking extra distinctive is its potential to detect a number of tick-borne infections directly, and in a well timed style.
“Moreover, our platform will detect anaplasmosis, babesiosis, and Lyme illness at an early stage non-invasively in comparison with the opposite obtainable methods that take a look at 4 to 6 weeks after the event of an infection,” Srivastava mentioned. “Most assessments obtainable presently are symptom-based and signs develop 4 to 6 weeks after a tick chunk. Our platform can detect these ailments early on, inside one to 2 weeks, in underneath half-hour utilizing a transportable diagnostic device. If profitable, this device could also be helpful for quite a lot of well being functions past tick-borne ailments.
“Fast detection might scale back the danger of hospitalization, physician’s visits and stop the illness from progressing right into a continual, life-long situation.”
