Background:

• Copper (Cu²⁺) poses significant risks to human health and aquatic ecosystems.
• Effective methods for detecting and monitoring copper in water are crucial for environmental safety.
• Existing detection methods often lack the desired speed, sensitivity, or economic viability.

Purpose of the Study:

• To develop and evaluate a novel fluorescent sensor for the detection of copper cations (Cu²⁺).
• To assess the sensor's performance in various environmental conditions and its selectivity towards copper.
• To establish a rapid, sensitive, and cost-effective method for copper detection in water samples.

Main Methods:

• Synthesis of a poly(amidoamine) dendrimer modified with a naphthalimide fluorescent derivative.
• Evaluation of the sensor's fluorescence properties in solvents of varying polarity.
• Testing the sensor's response to different metal cations, including copper (Cu²⁺).
• Quantification of copper detection limits in aqueous solutions.

Main Results:

• The dendrimer-naphthalimide system exhibited significant fluorescence changes upon interaction with copper cations.
• The sensor demonstrated high sensitivity, enabling the detection of copper at low concentrations.
• The system showed selectivity for copper over other tested metal cations.
• The sensor's performance was stable across different solvent polarities.

Conclusions:
