Scholarcy highlights

  • Emerging Smart Material forSince the fortuitous discovery of carbon dots in 2004, the interest in these luminescent nanomaterials has been increasing exponentially
  • Several stimuli-responsive properties of the CDs have been identified, which concurrently inspired to develop new strategies for the detection of a wide array of analytes with special efforts seen in environmental monitoring and healthcare applications such as the detection of toxic heavy metals, chemicals, and compounds/cells of clinical importance
  • The CD’s optoelectronic and surface chemical properties are seen as guiding factors for various sensitive stimuli-responsive signals, which led to acquire highly sensitive optical behaviours such as photoluminescence and chemiluminescence, and electrochemiluminescence in the detection processes
  • The optical response-based smart material properties of CDs are greatly influenced by the synthesis route of these 0-dimensional carbon nanomaterials
  • Despite the progress made, the smart material research on CDs is still in its infant stage compared to the other carbon nanomaterials
  • A simple and straightforward synthesis strategy is important for scaling up their production with uniform size and intended applications for commercial success
  • Elucidation of detailed mechanisms on the external stimuli led-change or generation of the optical properties will help developing
