Fluorescein-labeled starch maleate nanoparticles as sensitive fluorescent sensing probes for metal ions

open access: yes, 2014
Fluorescein 5(6)-isothiocyanate starch maleate (FISM) nanoparticles were prepared by covalently attached fluorescein 5(6)-isothiocyanate (FITC) with starch maleate.

Dual-tracer measurements of concentration profiles in the aqueous mass boundary layer [PDF]

open access: yes, 1995
A combination of two laser-induced fluorescence (LIF) techniques for measurements of vertical concentration profiles of dissolved gases and thus the investigation of micro-turbulence in the aqueous mass boundary layer at a free interface is presented ...

Fluorescein-Induced Allergic Reaction

open access: yes, 1998
Background: Adverse reactions following intravenous sodium fluorescein are very unusual and their mechanism is still uncertain. We report the case of a patient who suffered an adverse reaction during a fluorescein ocular angiography.
