Abstract Carbon dots and Fe3O4@Au were synthesized to develop a new biosensor to detect DNA target. We investigated the photoluminescence property of carbon dots (CDs) in the presence of Fe3O4-capped Au (Fe3O4@Au). Firstly, we designed two dedicated

Optimizing the Efficiency of a Cytocompatible Carbon-Dots-Based FRET Platform and Its Application as a Riboflavin Sensor in Beverages

Autor: Roberto Sotolongo-García, Eustolia Rodríguez-Velázquez, Manuel Alatorre-Meda, Mercedes T. Oropeza-Guzmán, Antonio Tirado-Guízar, Georgina Pina-Luis

Publikováno v: Nanomaterials, Vol 11, Iss 8, p 1981 (2021)

In this work, the Förster resonance energy transfer (FRET) between carbon dots (CDs) as energy donors and riboflavin (RF) as an energy acceptor was optimized and the main parameters that characterize the FRET process were determined. The results wer

Maximum Entropy Method-Based Acceptor Triplet-State Fluorescence Correlation Spectroscopy Analysis for Determination of Donor–Acceptor Distance Distribution: Theory and Simulation

Autor: B. L. Chen, Z. Y. Guo, T. S. Chen

Publikováno v: IEEE Photonics Journal, Vol 7, Iss 3, Pp 1-10 (2015)

A maximum entropy method-based acceptor triplet-state fluorescence correlation spectroscopy (tsFCS) analysis, i.e., tsFCS fluorescence resonance energy transfer (tsFCS-FRET), was proposed to resolve the donor-acceptor distance (R) distribution of a F
