چکیده
A highly sensitive and selective Hg probe 4 based on rhodamine-b was developed and characterized. In consideration of environmental and biological application, we connected a water soluble receptor group (sulfonated β-naphtol) and rhodamine-b together through hydrazine hydrate in high yield. The result turns out that this compound not only exhibits excellent sensitivity and selectivity toward Hg, but also shows well cell permeability and compatibility in vitro.

متن کاملSensitivity evaluation of rhodamine B hydrazide towards nitric oxide and its application for macrophage cells imaging.
A colorless and non-fluorescent rhodamine derivative, rhodamine B hydrazide (RH), is applied to detect nitric oxide and form fluorescent rhodamine B (RB). The reaction mechanism of RH with NO is proposed in this study. The probe shows good stability over a broad pH range (pH>4). Furthermore, fluorescence intensity of RH displays an excellent linearity to the NO concentration and the detection l...
