An ultrasensitive electrochemiluminescence (ECL) immunosensor was developed using PtAg@carbon nanocrystals (CNCs) as excellent labels based on carbon nanotubes-chitosan/AuNPs (CNT-CHIT/AuNPs) composite modified screen-printed carbon electrodes (SPCEs) for prostate protein antigen (PSA) detection. The CNCs were obtained simply by electro-oxidation of(More)
A facile and ultrasensitive electrochemiluminescent (ECL) immunosensor for detection of prostate-specific antigen (PSA) was designed by using CdTe quantum dots coated silica nanoparticles (SiO2@QDs) as bionanolabels. To construct such an electrochemiluminescence immunosensor, gold nanoparticles-dotted graphene composites were immobilized on the working(More)
Recently, there have been a number of studies on the association between cyclin D1 G870A polymorphism and nasopharyngeal carcinoma risk. However, the results of previous reports remain controversial and ambiguous. Thus, we performed a meta-analysis to explore more precisely the association between cyclin D1 G870A polymorphism and the risk of nasopharyngeal(More)
The Ti foil (0.1 mm thickness, 99.6 % purity, Goodfellow, England) was cleaned by using distilled water and acetone and dried off with N 2 gas. The bare Ti foil was anodized in an ethylene glycol solution containing NH 4 F (0.38 wt%) and H 2 O (1.79 wt%) and placed in a well-insulated bath for 3 h at 30 V and at 20 ℃ using a dc power supply (N5753A model,(More)
A molecular imprinted polymer thin film for photoelectrochemical (PEC) sensing of chlorpyrifos molecules was first constructed by electropolymerizing the o-phenylenediamine (o-PD) monomer and chlorpyrifos template molecule on gold nanoparticles-modified titanium dioxide nanotubes. The resulting PEC sensors were characterized by scanning electron microscopy,(More)
BACKGROUND To glean insights into the relationship among hepatitis B virus (HBV) genotype/subgenotypes, A1762T/G1764A mutations and advanced liver disease such as liver cirrhosis (LC) and hepatocellular carcinoma (HCC) in Southeast China. METHODS A case-control study was performed, consisting of chronic hepatitis B (CHB) patients (n=160), LC patients(More)
