Fluorescent carbon quantum dots for effective tumor diagnosis: A comprehensive review

Carbon quantum dots (CQDs)-modified polymers: a review of non-optical applications

“…Based on these basic mechanisms, significant improvements in smart polymer performance, mechanical properties, and functional aspects are summarized in this review (Table S1†). Unlike previous reviews, 15–24 the optical characteristics and charge transfer behavior of CQDs and polymers are not in the scope of this review.…”

Carbon quantum dots in bioimaging and biomedicines

“…The need for efficient multimodal imaging probes is growing, combining various imaging modalities like magnetic resonance (MRI), photoacoustic (PA), and imaging using computed tomography (CT) ( Prabhuswamimath, 2022 ; Rajasekar et al, 2022 ; Kanungo et al, 2023 ; Latha et al, 2023 ). PA imaging is a hybrid method of imaging that combines optical and ultrasonic modalities for deep tissue penetration and great spatial resolution ( Rajasekar et al, 2022 ; Latha et al, 2023 ). CQDs exhibit substantial absorption coefficients in the red to near-infrared spectrum when used as PA contrast agents and can transform light into heat ( Ge et al, 2015 ; Prabhuswamimath, 2022 ).…”

Reinforcement using undoped carbon quantum dots (CQDs) with a partially carbonized structure doubles the toughness of PVA membranes

“…The addition of CQDs changes the crystallization dynamics, phase segregation, and crystal growth as it serves as a crosslinking agent. 5,6 In addition, CQD composites have an advantage over other nanoreinforcements as they do not require surface modications or dispersing agents. Furthermore, their high surface area causes stress dissipation, thus enhancing the mechanical strength of the polymeric structures, i.e., increasing their strength and elongation.…”
