Molecular First Hyperpolarizabilities of a New Class of Asymmetric Squaraine Dyes [PDF]

open access: yes, 1994
The molecular first hyperpolarizabilities (β) of a series of asymmetric squaraine dyes have been measured by electric-field-induced second harmonic generation; the dyes have negative β-values whose magnitudes are comparable to 4-N,N-dimethylamino-4 ...

“Dye another day!” – dyes in ophthalmology

open access: yesIndian Journal of Ophthalmology, 2023
Background: Dyes are substances that are an integral part of ocular procedures and surgeries. In Clinical practice, dyes help in better visualization and aid in diagnoses of ocular surface disorders. In Surgical practice, dyes help in better resolution of the structures that are otherwise naked to the surgeon’s eyes.
