General description
Application
- A novel and efficient voltammetric sensor for the simultaneous determination of alizarin red S and tartrazine: Utilizing buffer concentrates, this study develops a poly(leucine) functionalized carbon paste electrode. It demonstrates the crucial role of buffer solutions in enhancing the accuracy and sensitivity of voltammetric sensors in environmental and biochemical assays (Moulya et al., 2024).
- Nitrocellulose for Prolonged Permeation of Levofloxacin HCl-Salicylic Acid In Situ Gel: Research grade buffer concentrate is employed to maintain pH stabilization during the formulation of nitrocellulose-based in situ gels, improving drug delivery systems for pharmaceutical applications (Khaing et al., 2024).
- The development of lateral flow devices for urinary biomarkers to assess kidney health: This study integrates high-purity buffer concentrates for the optimal performance of lateral flow devices, underscoring their importance in clinical diagnostics and biochemical assays (D′Souza et al., 2024).
- Determination of lamotrigine in human plasma by HPLC-PDA: Buffer concentrates are crucial in the forensic analysis of lamotrigine levels in plasma, illustrating their significance in enhancing the reliability and accuracy of pharmaceutical testing (Sánchez-Sellero et al., 2024).
- On-Chip Electrochemical Sensing with an Enhanced Detecting Signal Due to Concentration Polarization-Based Analyte Preconcentration: The use of buffer concentrates is essential in creating on-chip electrochemical sensors, facilitating significant advancements in analytical chemistry through improved detection signals (Park et al., 2024).
