A HOMOGENEOUS BIOSENSOR FOR CARBOHYDRATE ANTIGEN 153 DETECTION IN HUMAN SERUM BASED ON UPCONVERSION FLUORESCENCE RESONANCE ENERGY TRANSFER

A homogeneous biosensor for carbohydrate antigen 153 detection in human serum based on upconversion fluorescence resonance energy transfer

Quantitative determination of carbohydrate antigen 153 (CA153) in human serum plays an important role in early diagnosis of breast cancer.In this work, a highly sensitive and selective biosensor for CA153 detection was developed based on a fluorescent resonance energy transfer (FRET) strategy, in which near-infrared (NIR)-excitable upconversion meg

BiFeO3-BaTiO3: A new generation of lead-free electroceramics

Lead-based electroceramics such as Pb(Zr.Ti)O3 (PZT) and its derivatives have excellent piezoelectric, asi178mc pyroelectric and energy storage properties and can be used in a wide range of applications.Potential lead-free replacements for PZT such as potassium sodium niobate (KNN) and sodium bismuth titanate (NBT) have a much more limited range of
