Tyndall-Effect-inspired assay with gold nanoparticles for the colorimetric discrimination and quantification of mercury ions and glutathione

Interpreting the Therapeutic Efficiency of Multifunctional Hybrid Nanostructure against Glioblastoma

“…The prepared PTX@ANG/FA-NPs were characterized initially via scattering mechanism under laser-beam irradiation, and a bright “channel” could be observed in the solution of PTX@ANG/FA-NPs, indicating a promising Tyndall effect, see Figure (a). This is a new nanosensing method for naïve, subtle, definite, visual detection of PTX@ANG/FA-NPs that showed better result compared to a previous one. , Then TEM exhibited sphere or similar spherical morphologies with diameters 100–200 nm in aqueous sodium cholate solution as shown in Figure (b). The morphology was novel and ideal for drug delivery.…”

Cucurbituril-protected dual-readout gold nanoclusters for sensitive fentanyl detection

“…This observation was consistent with the literature, where TE showed a clear correlation with colloidal size in the solution. 23,24 We further utilized this unique the TE response for FEN detection with the naked eye. As shown in Fig.…”

Tyndall-effect-based colorimetric assay with colloidal silver nanoparticles for quantitative point-of-care detection of creatinine using a laser pointer pen and a smartphone

“…However, the LSPR-based colorimetric signaling still suffers from unsatisfactory visually-distinguishing ability and the requirement of expensive desktop equipment like UV-vis spectrometer to realize quantitative determination. 31 To response these challenges, more recently, our group has used the Tyndall effect (TE) of colloidal AuNPs to demonstrate an alternative approach for highly sensitive, low-cost and equipment-free quantification of metal ions including Ag + , 32 small biomolecules like cocaine 33 and glutathione, 34 and interferon-γ protein marker 33 with significantly enhanced colorimetric signaling efficiency. The TE, one of basic optical features of a colloid which is named for the 19th-century British physicist John Tyndall, generally indicates a “visible light path” originated from the scattering of a light beam by the colloidal nanoparticles.…”
