FRET from ZnSe/ZnS QDs to coumarin dyes: Role of acceptor dipole moment and QD surface states on FRET efficiency

Theoretical Investigation of Two Antiemetic Drugs at DFT Level

“…The notion of dipole moment in physics and chemistry is expressed by the existence of many electrostatic dipoles (Dorohoi et al, 2019). It is a heteroclite distribution of electrical charges such that the barycenter of the positive charges does not coincide with that of the negative charges (Inamdar et al, 2018). The simplest dipole is therefore a pair of two charges, of opposite signs, separated by a non-zero distance (Pal, 2020b).…”

Turn-off/turn-on biosensing of tetracycline and ciprofloxacin antibiotics using fluorescent iron oxide quantum dots

“…It's noted that the FRET efficiency is related to the distance between the donor and the acceptor because energy transfer efficiency is inversely related to the sixth power of the bonding distance as the energy transfer efficiency decreases signicantly. 23 However, most of the FRET sensor research studies focus on organic uorophores, which have some shortcomings, including spectral crosstalk, 24 photobleaching, 25,26 and direct acceptor excitation, 26 which makes it difficult to avoid direct acceptor excitation at the excitation wavelength required to excite donor molecules effectively.…”

A highly sensitive fluorescent immunosensor for sensitive detection of nuclear matrix protein 22 as biomarker for early stage diagnosis of bladder cancer

“…During FRET, an excited donor uorophore transmits its excitation energy to the adjacent acceptor uorophore through long-range intermolecular dipole-dipole interaction upon the overlap of their respective emission and absorption spectra. [17][18][19] This study was conducted to develop a highly-sensitive and rapid FRET-based nano-biosensor to detect NMP22 in urine samples. The principle is based on energy transfer between two QDs, named as QD (D) (emission at 530) and QD (A) (emission at 610).…”
