Abstract
This study explored the responses of cotton fabrics functionalized with lactate-responsive and non-responsive polymers, focusing on color and pattern changes. Circular samples, conjugated with lactate-responsive polymers and stained with indigotrisulfonate, showed distinct color shifts from blue to colorless as lactate concentration increased. This effect was linked to dye release triggered by lactate binding to boronic acid groups in the polymer. In contrast, samples with non-responsive polymers displayed minimal color changes. RGB analysis of photographs revealed significant R-value shifts in lactate-responsive samples, suggesting potential for semi-quantitative lactate detection via simple measurements. Additionally, facial pattern samples visualized the lactate response, transforming a smiling face into a crying face with rising lactate levels. Similar results were observed with another anionic dye, Acid Red 18. These findings demonstrate the promise of designing wearable lactate sensors that enable easy, burden-free monitoring.
期刊介绍:
Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied.
Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media.
The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
