Based on the inhibitory effect of uric acid (UA) on luminol-Co(2+) chemiluminescence (CL) system, a sensitive method for the determination of UA at nanomolar level by flow injection (FI) CL was proposed. The proposed method was successfully applied to real-time monitoring of UA excretion in human 24 h urine with different food intake, showing that meats,(More)
A Novel bandgap reference based on CMOS technology is presented in this paper. The main feature of the circuit is the wide input voltage range. It consists of two stages based on voltage-connection, for the first stage an improved structure is adopted to provide the relative high output voltage and for the second stage an amplifier is used to ensure the(More)
