Application of fluorescence resonance energy transfer to bioprinting

Diagnostics for SARS-CoV-2 infections

“…Furthermore, the labelled F1ab-LF* and F1ab-LB* primers react under the optimized conditions, and SARS-CoV-2 RNA is converted to cDNA with AMV-RT at 63 °C in 40 min. This reaction provides the material for subsequent LAMP amplification; the RT-LAMP system consists of the FITC products and digoxigenin, for the detection of F1ab and np primer 37 . RNA extraction is time consuming and expensive, and requires centrifugation steps, which EasyCOV RT-LAMP tests do not require.…”

A fluorescent aptasensor for highly sensitive and selective detection of carcinoembryonic antigen based on upconversion nanoparticles and WS2 nanosheets

“…Among all the above-mentioned analytical methods, the FRET-based homogeneous assay has attracted widespread attention because of its attractive advantages of high sensitivity, easy handling, single-step mix-andread analyses and time-saving. 7 Traditional uorescent materials (such as organic dyes) are prone to photobleaching and producing interference of scattered light and co-excitation of energy donors in FRET under the excitation of ultraviolet or visible light. In contrast, upconversion nanoparticles (UCNPs) are a new type of inorganic luminescent nanomaterials doped with rare earth ions, which can absorb infrared light and emit visible light.…”

Dominating Interlayer Resonant Energy Transfer in Type-II 2D Heterostructure

“…3 ET has already been proven as building block of many biological and chemical applications. [5][6][7][8] Despite the long history of discovery, 1 ET exploration is still on-going due to the fact that many promised applications are based on the idea of placing donor and acceptor in sub-nanometer proximity, to fully utilize the ET process. 9 Layered transition metal dichalcogenide (TMD) materials can be exfoliated down to atomically-thin monolayers (1Ls) and the optical bandgaps of these materials spans the broad range of near-infrared to deep ultraviolet in the electromagnetic spectrum.…”

“…When donor and acceptor are in close proximity and donor emission spectra overlaps with the acceptor absorption spectra, the excited state energy from the donor gets transferred to the acceptor via dipole–dipole interaction and subsequently released in the form of radiative energy emission from the acceptor. , ET, thus favorably occurs between parallel dipoles . ET has already been proven as the building block of many biological and chemical applications. − Despite the long history of discovery, ET exploration is still ongoing due to the fact that many promised applications are based on the idea of placing donor and acceptor in subnanometer proximity to fully utilize the ET process …”
