Molecularly imprinted polymer for Mucin 4 (MUC4) biomarker
Piloto, A.M.L.; Cerqueira, N.; Sales, Goreti(Introduction) Molecularly imprinted polymers (MIPs) were synthesized around quantum dots (QDs) to detect the protein biomarker MUC4, which is associated with pancreatic cancer (Kauretal.,2022; Mehrotraetal.,2024). In this approach, MIPs serve as biorecognition elements and are conjugated with cadmium telluride QDs to form the sensing system. The fluorescence of these imprinted polymers is quenched as MUC4 conc...
Ratiometric determination of CA19-9 using fluorescent carbon dots and yellow-em...
Rodrigues, E.; Piloto, A.M.L.(Introduction) Quantum dots (QDs) have high fluorescence, chemical stability and sensitivity and optical properties. Traditional QDs probes have a single peak, leading to some problems such as systemic errors due to detection conditions and fluorescence background and systemic instability. Ratiometric methods eliminate random changes in QDs fluorescence intensity and reduces optical fluctuations not caused by t...
