A ratiometric luminescence sensing platform based on lanthanide-based silica nanoparticles for selective and sensitive detection of Fe³⁺ and Cu²⁺ ions

Abstract

Detection of Fe(III) and Cu(II) in water is highly desirable because their abnormal levels can cause serious harms to human health and environmental safety. In this work, a novel terbium-containing...

One-pot in situ functionalization of cellulose in a CO2 switchable solvent for the fluorescent detection of Fe3+

“…6,11–19 In particular, fluorescent sensors developed with natural polymeric materials have gained increasing attention because they are sustainable, eco-friendly, biodegradable, and cost-effective. 20,21 As the most abundant renewable raw material, 22 cellulose is one of the most commonly used starting materials for the development of fluorescent sensors. 23–30 For example, Wang et al 11 synthesized a new fluorescent probe for Fe 3+ by the condensation reaction of dialdehyde cellulose and a coumarin derivative, which exhibited a distinct “off” fluorescence response to Fe 3+ .…”
