Area of Science:

Analytical Chemistry
Supramolecular Chemistry

Background:

Amino acids are crucial biomolecules with diverse functions.
Distinguishing amino acids from their derivative amines is important in biological and chemical analysis.
Amino acid decarboxylases convert amino acids into amines.

Purpose of the Study:

To develop a "turn-on" fluorescent sensor array for detecting amino acids in aqueous solutions.
To investigate the array's capability in discriminating between amino acids and amines.

Main Methods:

Utilized a cucurbituril-based supramolecular system as a "turn-on" fluorescent sensor.
Employed a sensor array for simultaneous detection and analysis.
Applied multivariate statistical methods, including Linear Discriminant Analysis (LDA) and Hierarchical Component Analysis (HCA), for data interpretation.

Main Results:

The cucurbituril-based sensor array demonstrated effective "turn-on" fluorescence response for amino acid detection.
Multivariate analysis (LDA and HCA) successfully differentiated amino acids from their corresponding amines.
The sensor array showed high specificity in distinguishing these related compounds.

Conclusions:

The developed cucurbituril-based fluorescent sensor array is a viable tool for analyzing amino acids in water.
The array, coupled with multivariate analysis, offers a robust method for discriminating amino acids from amines, relevant to studying decarboxylase activity.
