# Chemical-Sniffing Phones The NASA Homeland Security Cell-All Program for Sensing Chemicals By Katherinev123 | Published 2009-11-12 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/nasa-homeland-security-cell-all-program References: [nasa.gov](http://www.nasa.gov/centers/ames/news/features/2009/cell_phone_sensors.html) Now you can detect and distinguish between methane, ammonia, chlorine gas and other chemicals, thanks to the [NASA](https://www.trendhunter.com/trends/ar-nasa-app) Homeland Security Cell-All Program. NASA has created an [iPhone](https://www.trendhunter.com/trends/apple-1) application that acts as a [chemical sensor](https://www.trendhunter.com/trends/hafi). It uses a silicon-based sensing chip with sixteen nanosensors to sniff small amounts of chemicals. The chemical-smelling application from the NASA Homeland Security Cell-All Program could be used to acquire early information about a chemical attack, confirm suspicions of methane emissions from local factories, or just give users information about the chemicals present in their daily environments. ## Trend Insights (Trend Hunter) - Score: 2.9/10 - Popularity: 42% | Activity: 36% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### What's Driving This Trend - **Chemical Sensing Applications:** Developing smartphone applications with chemical sensing capabilities can revolutionize early detection of chemical threats and improve user safety. - **Nanosensor Technology:** Advancements in nanosensor technology have the potential to enhance the accuracy and sensitivity of chemical detection devices. - **Iot Sensor Integration:** Integrating chemical sensing capabilities into Internet of Things (IoT) devices can provide real-time monitoring and alert systems for various industries. ### Who This Affects Most - **Healthcare:** Adopting chemical-sensing smartphones can help healthcare professionals identify hazardous substances in clinical settings and improve patient safety. - **Environmental Monitoring:** Deploying chemical-sensing applications in industrial areas can help monitor air quality, detect pollutants, and ensure compliance with environmental regulations. - **Public Safety and Security:** Integrating chemical-sensing capabilities in surveillance systems can enhance threat detection and response measures at public venues and critical infrastructure. ## Related on Trend Hunter - [Smell-Based Disease Detectors](https://www.trendhunter.com/trends/diagnoze.md) - [Nicotine-Detecting Wearables](https://www.trendhunter.com/trends/skinworn-sensor.md) - [Scent-Detecting Robot Concepts](https://www.trendhunter.com/trends/sniff-robot.md) - [Smartphone Metal Detectors](https://www.trendhunter.com/trends/metal-detector1.md) - [Scent-Encapsulated Phone Cases](https://www.trendhunter.com/trends/aroma-scent-phone-case.md) - [Fabric-Analyzing Smartphone Devices](https://www.trendhunter.com/trends/nearinfrared-spectroscopy-system.md) - [Proactive Tracker Detection Apps](https://www.trendhunter.com/trends/detection-app.md) - [Narcotic-Identifying Drug Devices](https://www.trendhunter.com/trends/rigaku.md) - [Multipurpose Scent-Releasing Wearables](https://www.trendhunter.com/trends/nosewise.md)
