Mobile Instrumentation for the Detection and Sampling of Aerosol Particles

Hazardous airborne particles pose a risk for health and safety in a variety of environments and thus detection of these small particles is essential. Current particle magnification systems are bulky and require a lot of power for operation, making them unsuitable to easily detect and analyze small particles in mobile and personal settings.

Occupational Safety: Portable Exposure Assessment System for Prevention of Musculoskeletal Injury

CDC researchers have developed the Portable Exposure Assessment System (PEAS), a field-based, remotely deployed tool to monitor and provide early warning of working conditions that have a high likelihood of musculoskeletal injury. PEAS is a noninvasive, real-time, instrument-based system. Sensor technology simultaneously measures and collects data regarding the body loads and awkward postures imposed by package handling as well as driving-related, low-frequency vibrations.

Respirator Protection Devices and Methods to Detect and Remove Toxic Gases from the Air - Cobinamide Encapsulated Silica-based Materials for Respirator Canisters

A respirator protects the wearer from inhaling dangerous substances, such as chemicals and infectious particles. CDC developed devices and methods to detect and remove chemicals such as hydrogen cyanide, cyanogen, hydrogen sulfide, nitrite, and nitric oxide from the air for those wearing respirators. Cobinamide (a Vitamin B12 analog with a high affinity to cyanide) molecules are immobilized within a silica matrix that allows for the infiltration and containment of gaseous chemicals.

Near Real-time, Low-cost, Hand-held Sensors for Measuring Elemental Concentration of Airborne Particles for Indoor or Outdoor Air Quality Monitoring

Airborne particles can have great impact on air quality, weather, and human health. In particular, long-term inhalation of toxic particulate matter in workplaces could pose a significant health risk. NIOSH scientists have developed a new, low-cost approach based on application of atmospheric radio frequency glow discharge (rf-GD) optical emission spectroscopy for near real-time measurement of elemental concentration in aerosols. The method involves collection of aerosol particles on an electrode tip in a coaxial microelectrode system, followed by excitation of the particles using rf-GD.

Methods for near real-time aerosol chemical analysis for environmental and occupational monitoring

­Exposures to hazardous airborne particles can pose a significant health risk to those routinely exposed in ambient air and industrial work environments. Measuring chemical composition and concentration of aerosol particles is important to preventing worker exposures and protecting health.

Monoclonal Antibody for Specific Detection of the Transcription Factor Eos (Ikzf4) in Regulatory T Cells

Regulatory T cells (Tregs) are immune cells that keep the immune system balanced and prevent autoimmunity. Tregs depend on a protein called Eos (Ikzf4) that helps turn genes on and off for their development and function, but until now, antibodies used to detect and study Eos were unreliable.

EV-D68 Monoclonal Antibodies Isolated from Immunized Rhesus Macaques

Enterovirus D68 (EV-D68) has been linked to the widespread outbreaks of respiratory illness and acute flaccid myelitis (AFM) in the United States and Europe in 2014, 2016, and 2018. Although EV-D68 is now the most frequently encountered enterovirus (41.1% of cases), with an estimated global prevalence of 4%, there are no specific, FDA-approved therapeutic interventions targeting this virus.

Polyvalent Influenza Virus-Like Particles (VLPs) and Use as Vaccines

Influenza virus is a major public health concern, causing up to 500,000 deaths annually. The current strategy of reformulating vaccines annually against dominant circulating strains leads to variable protective efficacy and is unlikely to protect against novel influenza viruses with pandemic potential. Thus, there is a great need for a vaccine that provides “universal” protection against influenza viruses.
