Photophysical properties of carbon quantum dots

Luminescent carbon quantum dots derived from syzygium cumini seeds with endogenous anti-oxidant and cytotoxic potency including in vitro photoluminescence and live cell imaging

“…Owing to distinctive optical features, the abundance of surface passivated active groups (such as hydroxyls, carboxylates, amines, and amides), high stability, and electron mobility, carbon dots have drawn significant attention and have been regarded as a novel material in the realm of carbon chemistry. 1 CDs exhibit several advantages, notably photoluminescence, excellent quantum yield, minimal toxicity, nanoscale size, remarkable biological compatibility, and abundant resources. 2 Carbon dots encompass diverse applications such as sensing (of ions, amino acids, and many other charged particulates), catalysis, super capacitance, solar cells, 3 and biomedicine.…”

Efficient and eco-friendly detection of gabapentin using nitrogen-doped carbon quantum dots: an analytical and green chemistry approach

“…1,2 They are characterized by their good biocompatibility, bright luminescence, high hydrophilicity, low cytotoxicity, and tunable photoluminescence. 3,4 These properties make them highly versatile and suitable for numerous applications including bioimaging, drug delivery, tumour diagnosis, catalysis, sensors, and even in cancer therapy. [5][6][7][8][9] Furthermore, carbon quantum dots are known for their low toxicity and low cost of production, making them an attractive alternative to other types of quantum dots such as semiconductor quantum dots or commercial organic dyes.…”

Review of Carbon Dot-Based Drug Conjugates for Cancer Therapy

“…The change in the concentration of the precursor used and surface passivating agents leads to differences in the fluorescence properties, size, and surface functionalization of CDs. , CDs-based targeted nanodelivery applications for cancer therapy have sparked interest in the past decade due their biocompatible nature. However, the current literature lacks a comprehensive review on CDs-based anticancer drug conjugation and delivery for therapeutic applications.…”
