| 摘 要： | To date the most popular biosensor reported in the literature are those employing redox enzymes coupled with amperometric detection. For the construction of this kind of biosensors, a general, broadly applicable method for enzyme immobilization still needs to be discovered. One of recent trends is based on the use of new carriers, such as nanosized particles1,2. Amorphous selenium nanoparticles (SN) are demonstrated not only unique photoelectric, semiconducting and X-ray-sensing properties,…

| Abstract: | The well-distributed, stable selenium nanoparticles (10 nm) with good adhesive ability and biocompatibility were successfully synthesized by using the template of chitosan cross-linked with glutaradehyde. The resulting selenium nanoparticles were used as a new carrier for horseradish peroxidase to construct H2O2 biosensors with good performances. |
