Sensory development for heavy metal detection: A review on translation from conventional analysis to field-portable sensor

In recent decades, contaminations with heavy metals ions have adversely affected the environment, food safety, and human health. Heavy metals, leaching to water sources from industrial effluents, can enter into aquatic chains of humans animals a variety anthropogenic sources. metal detection has been an intensive area research today. Both laboratory-based analytical instruments innovative sensor devices like electronic nose, tongue, bio/chemical sensors increasingly emerged meet demand for legislative actions on environmental pollution control early warning. These evolving technology developments particularly in nanotechnology become key contributing factors detection. This endeavor aims at exploring this field detail understand principles behind flourishing science summarize development technologies. article also gives brief review commercially available portable that potential next gold standard
