| 520 | |a Abstract This work presents the development of a novel electrochemical sensor for caffeine detection in sports drinks, utilizing molecular imprinting technology with surface-imprinted nanoparticles. Key to this study is the synthesis of caffeine-imprinted polypyrrole nanoparticles via electropolymerization, which displayed a high specific surface area (25 $ m^{2} $/g) and efficient template binding. The sensor exhibited a notable linear detection range from 30 to 150 µM and a significantly low limit of detection at 2.5 µM. Characterization of the nanoparticles was rigorously conducted using SEM, FTIR, and BET analysis. Optimized sensing conditions were established at pH 5, with a 5 min accumulation time and a scan rate of 50 mV/s, ensuring high sensitivity and selectivity. Practical application was demonstrated through the accurate detection of caffeine in commercially available sports drinks, with recovery rates ranging from 97.6 to 101.5%. This research underscores the potential of molecularly imprinted polymer-based sensors in simplifying and enhancing the detection of caffeine in complex matrices, offering a promising tool for health monitoring and sports performance analysis. | ||

Abstract This work presents the development of a novel electrochemical sensor for caffeine detection in sports drinks, utilizing molecular imprinting technology with surface-imprinted nanoparticles. Key to this study is the synthesis of caffeine-imprinted polypyrrole nanoparticles via electropolymerization, which displayed a high specific surface area (25 $ m^{2} $/g) and efficient template binding. The sensor exhibited a notable linear detection range from 30 to 150 µM and a significantly low limit of detection at 2.5 µM. Characterization of the nanoparticles was rigorously conducted using SEM, FTIR, and BET analysis. Optimized sensing conditions were established at pH 5, with a 5 min accumulation time and a scan rate of 50 mV/s, ensuring high sensitivity and selectivity. Practical application was demonstrated through the accurate detection of caffeine in commercially available sports drinks, with recovery rates ranging from 97.6 to 101.5%.

Key to this study is the synthesis of caffeine-imprinted polypyrrole nanoparticles via electropolymerization, which displayed a high specific surface area (25 $ m^{2} $/g) and efficient template binding. The sensor exhibited a notable linear detection range from 30 to 150 µM and a significantly low limit of detection at 2.5 µM. Characterization of the nanoparticles was rigorously conducted using SEM, FTIR, and BET analysis. Optimized sensing conditions were established at pH 5, with a 5 min accumulation time and a scan rate of 50 mV/s, ensuring high sensitivity and selectivity. Practical application was demonstrated through the accurate detection of caffeine in commercially available sports drinks, with recovery rates ranging from 97.6 to 101.5%. This research underscores the potential of molecularly imprinted polymer-based sensors in simplifying and enhancing the detection of caffeine in complex matrices, offering a promising tool for health monitoring and sports performance analysis.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Molecularly imprinted polymers</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Polypyrrole nanoparticles</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Electrochemical sensing</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Caffeine analysis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sports nutrition</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wei, Dongmei</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of food measurement and characterization</subfield><subfield code="d">Springer US, 2012</subfield><subfield code="g">18(2024), 5 vom: 15.

Electrochemical detection of caffeine in sports drinks based on molecular imprinting technology |
| abstract |
Abstract This work presents the development of a novel electrochemical sensor for caffeine detection in sports drinks, utilizing molecular imprinting technology with surface-imprinted nanoparticles. Key to this study is the synthesis of caffeine-imprinted polypyrrole nanoparticles via electropolymerization, which displayed a high specific surface area (25 $ m^{2} $/g) and efficient template binding. The sensor exhibited a notable linear detection range from 30 to 150 µM and a significantly low limit of detection at 2.5 µM. Characterization of the nanoparticles was rigorously conducted using SEM, FTIR, and BET analysis. Optimized sensing conditions were established at pH 5, with a 5 min accumulation time and a scan rate of 50 mV/s, ensuring high sensitivity and selectivity. Practical application was demonstrated through the accurate detection of caffeine in commercially available sports drinks, with recovery rates ranging from 97.6 to 101.5%. This research underscores the potential of molecularly imprinted polymer-based sensors in simplifying and enhancing the detection of caffeine in complex matrices, offering a promising tool for health monitoring and sports performance analysis. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
