Carbon Nanomaterials-Based Electrochemical Sensors for Heavy Metal Detection

Waste-derived carbon nanodots for fluorimetric and simultaneous electrochemical detection of heavy metals in water

“…Based on the existing literature, electrochemical methods are less reported for the detection of heavy metal ions by using CNDs. 51,52 Unlike the fluorimetric method, the electrochemical one allows the simultaneous determination of these species. Hence, an electrochemical study was conducted to explore both the potential of electrochemical detection of heavy metal ions with the CNDs/SPCE sensor and their simultaneous detection.…”

Advancements in food quality monitoring: integrating biosensors for precision detection

“…39 Environmental conditions, such as temperature and pH, can impact the performance and longevity of biosensors, requiring careful storage and handling protocols. 40 In addition, standardization and regulatory considerations pose challenges in ensuring the consistency and reliability of biosensor measurements for regulatory compliance and widespread acceptance in the food industry. 41…”

Unveiling the potential of Ti3C2Tx MXene for gas sensing: recent developments and future perspectives

“…1,2 At present, several materials have been investigated and established for gas sensors, such as metal oxides (MO), carbon-based materials, metal-organic frameworks (MOF), conductive polymers, rare-earth oxides, etc. [3][4][5][6][7][8][9][10][11][12] Metal oxide semiconductor (MOS) can be classified into two types, n-type (e.g., ZnO, SnO 2 , TiO 2 , etc.) and p-type (e.g., SnO, CuO, WO 3 , etc.).…”
