Carbon nanodots prepared from o-phenylenediamine for sensing of Cu²⁺ions in cells

A carbon dots based fluorescent probe for selective and sensitive detection of hemoglobin

“…A c c e p t e d M a n u s c r i p t 9 To confirm the feasibility, CDs fluorescent probe was firstly utilized to detect HGB in synthetic samples which contained the above interfering substances. As indicated in Table 3, the values found for these synthetic samples were identical with the spiked values and the recoveries were obtained from 94.6% to 103.2%.…”

“…More attentions have been paid to CDs, including their synthesis and biochemical applications [6][7][8]. Recent studies based on the fluorescence variation of CDs in the detection process, CDs have been utilized to monitor many substances, such as Cu 2+ , Fe 3+ , methylmercury, and thrombin [9][10][11][12]. Vedamalai et al have developed a novel luminescence sensing system for Cu 2+ detection based on the fluorescence enhancement of CDs [9].…”

Red, Green, and Blue Luminescence by Carbon Dots: Full‐Color Emission Tuning and Multicolor Cellular Imaging

“…[9] To the best of our knowledge, however, only oPD has been used to prepare PL nanoparticles or CDs. [10] In this current study, we report on the preparation of multicolor PL CDs, having red, green, and blue (RGB; the three primary colors) emissions by using the three different phenylenediamines isomers, through a facile solvothermal method. The as-prepared CDs emit strong and stable luminescence in solution and in a polymer matrix under a single-wavelength ultraviolet-light excitation.…”

Red C-dots and C-dot films: solvothermal synthesis, excitation-independent emission and solid-state-lighting

“…The "top-down" route physically breaks macroscopic carbon materials into smaller nanomaterials, while the "bottom-up" route chemically generates C-dots through molecular selfassembly reactions from various small-molecule reagents. [9][10][11][12] Recently, the bottom-up route has attracted great attention and been widely used to prepare CDs since the precursor sources are abundant and the reaction is easy to operate.…”
