Ultrafast Pulses Coherently Control Function in a Living Cell

Via Photonics Media | November 17, 2017

Researchers have used light to excite a light-sensitive channel in the membrane of optogenetic mouse neurons. When the channels were excited, they allowed ions through, which caused the neurons to fire. The researchers say the same technique could be used on cells that are naturally responsive to light, such as retina cells.

Previous research has demonstrated the use of coherently controlled light beams to regulate chemical reactions, but according to the University of Illinois team, their study is the first to use coherently controlled light pulses to demonstrate how living cell functions can be modulated via opsins, by modifying fundamental optical properties of light interacting with the retinal chromophore… Continue reading.

Surgical Probe Seeks Out Where Cancer Ends and Healthy Tissue Begins

Via MDT | September 15, 2015

A new surgical tool that uses light to make sure surgeons removing cancerous tumors “got it all” was found to correlate well with traditional pathologists’ diagnoses in a clinical study, showing that the tool could soon enable reliable, real-time guidance for surgeons.

The interdisciplinary research team led by Stephen Boppart, a University of Illinois professor of electrical and computer engineering and of bioengineering, performed the study on 35 patients with breast cancers at the Carle Foundation Hospital in Urbana, Illinois. The results appear in the journal Cancer Research.
One difficult but crucial determination for surgeons and tissue pathologists is figuring out where a tumor ends. A solid tumor may be easily identifiable, but the tissue around the main body of the tumor, known as the margin, may contain cancerous cells as well. Because of this, excess tissue surrounding the tumor is typically removed, but the question lingers of whether any cancer cells remain to re-emerge later as tumors.

“In almost all solid-tumor surgeries, there’s a question of margins,” said Dr. Boppart, who also is a medical doctor. “Typically, surgeons will remove the tissue mass that contains the tumor and will send it to the lab. The pathologist will process, section and stain the tissue, then examine the thin sections on microscope slides. They look at the structure of the cells and other features of the tissue. The diagnosis is made based on subjective interpretation and often other pathologists are consulted. This is what we call the gold standard for diagnosis.”

Engineers Use Reflected Light to Illuminate the Mystery of Ear Infections

Via Scientific American | June 4, 2012

When a person suffers from chronic ear infections the culprit may be a film of bacteria or other microorganisms that builds up behind the eardrum, not unlike dental plaque on unbrushed teeth. Antibiotics are not always effective against this so-called biofilm, so it helps doctors greatly to know whether it is present before prescribing a course of treatment. Whereas conventional scopes aren’t able to see beyond the surface of the eardrum, a team of researchers from the University of Illinois has developed a new tool that can shed some light on the situation.

The device uses a non-invasive imaging system called optical coherence tomography (OCT) to collect high-resolution, three-dimensional tissue images from beams of light sent into the ear canal. The system can scan through the eardrum to any biofilm behind it. The researchers, who liken the process to ultrasound imaging that uses light instead of sonic waves, described their work last week in the online Early Edition of the journal Proceedings of the National Academy of Sciences.

Nowhere to Hide: New Device Sees Bacteria Behind the Eardrum

Via University of Illinois News Bureau | May 29, 2012

Doctors can now get a peek behind the eardrum to better diagnose and treat chronic ear infections, thanks to a new medical imaging device invented by University of Illinois researchers. The device could usher in a new suite of non-invasive, 3-D diagnostic imaging tools for primary-care physicians.

The research team, led by University of Illinois electrical and computer engineering professor Stephen Boppart, will publish their advance in the online Early Edition of the journal Proceedings of the National Academy of Sciences the week of May 28.

Ear infections are the most common conditions that pediatricians treat. Chronic ear infections can damage hearing and often require surgery to place drainage tubes in the eardrum, and problems can persist into adulthood.

Studies have found that patients who suffer from chronic ear infections may have a film of bacteria or other microorganisms that builds up behind the eardrum, very similar to dental plaque on unbrushed teeth. Finding and monitoring these so-called biofilms are important for successfully identifying and treating chronic ear infections.
