A University of Texas at Arlington electrical engineer has developed a novel cancer cell detection method that will improve early diagnosis through a tool that tracks cellular behavior in real time using nanotextured walls that mimic layers of body tissue.

Samir Iqbal, an associate professor in the Electrical Engineering Department, detailed his team's results in a recent Nature’s Scientific Reports paper called “Effects of Nanotexture on Electrical Profiling of Single Tumor Cell and Detection of Cancer from Blood in Microfluidic Channels.”

Iqbal worked on the project with Young-tae Kim, a UTA associate professor in the Bioengineering Department; Muhymin Islam, a STEM doctoral candidate; and engineering students Mohammad Motasim Bellah, Adeel Sajid and Mohammad Raziul Hasan.

Iqbal said his team noted the many layers of tissue in the human body and decided to develop something that would mimic that layering.

“The answer was in creating a nanotextured wall that fools blood samples into thinking its actual tissue,” Iqbal said. “We used inherent properties of the cell walls to create a diagnostic tool. The cancer cells behave differently as they come into contact with the nanotextured walls. They dance.”

Identifying those “dancing cells” will help doctors pinpoint cancer cells and start treatment earlier than allowed with current technology.

“Discovering the cancer earlier, before it metastasizes, is essential to surviving cancer,” Iqbal said. “Our device has the potential to do that.”

The published results stem from a 2014 $480,000 National Science Foundation grant that funded the design and creation of the device.

Iqbal has received nearly $1.4 million in grants since his arrival at UTA in 2007. Those grants included an NSF CAREER grant to create a nanoelectronic microfluidic biochip to detect biomarkers. He also directs the UTA Nano-Bio Lab and is an affiliated faculty for the UTA Bioengineering Department. Iqbal also is an adjunct professor in the Department of Urology at UT Southwestern Medical Center.

In addition to his numerous research accolades, Iqbal is a senior member of IEEE-USA, a member of Biomedical Engineering Society, American Physical Society, American Society of Mechanical Engineers and Biophysical Society. In 2013, Tau Beta Pi inducted him as an Eminent Engineer.

Khosrow Behbehani, dean of the UTA College of Engineering, said Iqbal’s research is groundbreaking.

“Dr. Iqbal and his colleagues are bringing engineering innovation to meet the challenge of early cancer detection," Behbehani said. “The research aligns with UTA’s Strategic Plan, particularly the focus on Health and the Human Condition. Dr. Iqbal’s device could greatly improve cancer survival rates, which is good news for humanity. There are very few people around the world whose lives have not been touched by this dreadful disease.”

BiosensorsBiosensors are devices used to detect an analyte using biological molecules specific to the analyte coupled to a detector. Biosensor instruments may be photometric, typically using surface plasma resonance (SPR), electrochemical or QCM (quartz crystal microbalance) biosensors. Biosensors should be selective, portable, robust and sensitive and have a fast response time. Systems may be manual or automated and usually have associated software.Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins. Find the best cell and tissue culture products, kits and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Lab-on-a-ChipLab-on-a-chip (LOC) technology uses microfluidic chips, such as microarrays, to perform biochemical assays on a small scale. Benefits of lab-on-a-chip include the small volume of sample required as well as the speed of analysis. In selecting lab-on-a-chip devices consider the assay, cost, reliability, sensitivity and signal to noise ratio.Data AnalysisData analysis hardware and software is available to make data processing straight-forward yet powerful. Data software can be used for math and stats, technical graphing and image analysis. In addition, software is available for specific data analysis of electrophoresis, densitometry, ELISA and DNA sequencing.Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.

Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.NanotechnologyNanotechnology, or nanotech, is an engineering technique using molecular scale functional systems. Applications of nanotechnology include medicine and medical devices, electronics, air and water purification, food science and energy production.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Automated Liquid HandlingAutomated liquid handling equipment is used to mix, dilute and dispense allotted volumes of liquid into microplates and other vessels automatically.
