Medical

Background

At its core, the Medical Industry's goal is to protect human health and to treat and care for the afflicted. University of North Florida sensor technology can help meet this objective by revolutionizing the process of early detection and diagnosis. UNF sensors reduce labor costs, streamline data capture, and push forward early detection and diagnostics screening to the initial point of patient contact.

Potential UNF Sensor Applications

UNF medical sensor applications are varied and numerous. In addition to the potential uses listed below, contact us to learn how UNF sensor technology can be tailored to meet your particular needs.

Routine and Acute Diagnosis 

  • Potential for early detection of diseases such as lung cancer and tuberculosis.  
  • Doctor office, clinic and emergency room use of hand-held and remote devices for immediate detection of bacteria and viruses, potentially including MRSA and Influenza A (H1N1). 
  • Platform technologies can instantly perform diagnoses without sending samples to central laboratories.  

Emergency Response 

  • Emergency response patient narcotics monitoring and cadaver recovery. On-site, real-time accurate test results for multiple microbes or chemicals.  
  • Elimination of delays in diagnostic results, diminishing the need for diagnostics from centralized laboratories.  

Public Health 

  • Potential detection of viruses and bacteria harmful to human health in restaurants, lodging, and tourist attractions.  
  • Restaurant and grocery store monitoring of refrigeration systems for bacterial growth and viruses.  
  • Detection of poisons, chemical mixtures, and hazardous pollutant effluences.  
  • Water treatment monitoring for pools or water parks.  
  • Monitoring and identification of chemicals in drinking water supply and in U.S. waterways.  

Public Transportation/Public Safety 

  • Detection of non-terrorist disease/microbial outbreaks.  
  • Monitoring of subways, airplanes, cruise ships, and public areas for health and safety concerns.  

Sensor Technology Overview

UNF researchers have developed four types of advanced sensor technologies: two of which employ the use of next-generation nanocrystalline thin-film layers (oxide semi-conductive gas and enhanced quartz crystal microbalance sensors); one that is the first in its field (photoelectric chemical sensors); and one that has highly developed microbial sensing capabilities (photoelectric microbe sensors). All are patented or patent-pending and all are component-based, multi-functional platform technologies.

Nanocrystalline Enhanced Quartz Crystal Microbalance Sensors (NCQCM)

UNF NCQCM sensors are electronic "e-noses," or devices that can learn to recognize many mixtures or combination of mixtures and are capable of mimicking the human senses of smell and taste. This innovative technology can categorize and identify mixtures, and then determine the brand and if the brand fits within the standards of quality. UNF NCQCM sensors are patent-pending and, when used orthogonally with the UNF oxide semi-conductive gas sensors, provide an even higher level of superior selectivity and sensitivity. UNF NCQCM sensors are customizable and can be configured to detect a wide range of analytes and have been tested with over 160 mixtures including alcohol beverages (individual types and brands), teas (brands), marker pens (brands), vapors, food and fruit products, explosive materials, petroleum fuels, adulterated fuels, alkenes, volatile organic compounds, aldehydes, ketones, and esters. See the detailed list of detected analytes. The sensors work at room temperature; the response time of the sensors is in near real-time.

Nanocrystalline Oxide Semi-Conductive Gas Sensors (NOS)

UNF Nanocrystalline Oxide Semi-Conductive Gas Sensors have been configured to detect numerous mixtures, including industrial toxic chemicals, chemical warfare agents, explosive materials, gases/vapors, and volatile organic compounds (VOC). See the a detailed list of detected analytes. These sensors have increased sensitivity and can detect chemicals in the parts per million ranges, with some chemicals in the parts per billion ranges. UNF gas sensors can continuously operate on battery power due to their low power requirements, and under many conditions, they do not require a heater to operate.

Photoelectric Chemical Sensors (PECS)

UNF Photoelectric Chemical Sensors can be "taught" to identify many chemicals. To date, PECS have been configured to identify over 90 chemicals. See the detailed list of detected analytes. This technology is an updated and enhanced version of colorimetric sensors. PECS have multiple independent channels each capable of detecting different chemicals in near real-time using microprocessor-based embedded systems, outputting the sensed data in multiple digital formats. In addition, this technology's small size makes it very convenient and highly portable. 

Photoelectric Microbe Sensors (PEMS)

UNF Photoelectric Microbe Sensors are a multi-functional sensor recognition platform that detects a very wide range of microbes (both viruses and bacteria) with a single device. PEMS have multiple independent channels each capable of detecting different microbes in near-real time using microprocessor-based embedded systems. UNF PEMS result in a dramatic reduction of time, labor, and cost needed to detect and identify microbes. In addition, PEMS sensors can be combined with PECS to sense both chemicals and microbes simultaneously.
