What is Portable smartphone platform based on tunable chiral fluorescent carbon dots for visual detection of L-Asp and L-Lys about?
Amino acids are involved in many physiological processes such as neurotransmitter transmission, protein synthesis and immune regulation, which play an indispensable role in life science. However, accurate monitoring of amino acid metabolism still faces a huge challenging due the lack of robust detection approaches. Herein, threecolor emission tunable fluorescent carbon dots (CDs) were successfully synthesized by a simple one-step solvothermal treatment using classical precursors. These multi-color CDs exhibited a bright and steady luminescence shifting from blue to red under UV-vis light excitation. Detailed characterization by various precision instruments demonstrated that the unique structure of the prepared polychromatic emission CDs was composed of sp 2 hybrid carbon nucleus and part of sp 3 hybrid carbon atom. These CDs displayed low cytotoxicity and excellent multi-color cell imaging ability at single wavelength excitation. Moreover, the chiral structure on the surface of the red emissive carbon dots (R-CDs) was well preserved at temperatures far below the melting point of the chiral precursor. Especially, the chiral red emissive CDs (R-L-CDs) as sensitive and selective fluo
