Titania and silica have been recognized as potential drug delivery system (DDS) carriers. For this application, controllable biocompatibility the suppression of initial burst are required, which can be provided by a calcium phosphate (CP) coating. However, it is difficult to control morphology CP coating on surface carrier particles owing homogeneous nucleation CP. In study, we report developme...

A novel electrochemical immunosensor for sensitive detection of cancer biomarker prostate-specific antigen (PSA) has been reported based on nanoporous gold (NPG) and hollow mesoporous silica microspheres (HSMs). The immunoassay was conducted by following the typical procedure for sandwich-type immunoreaction. Nanoporous gold (NPG) foils were immobilized onto a glassy carbon electrode (GCE) for ...

Silicon as the negative electrode material of lithium ion batteries has a very large capacity, the exploitation of which is impeded by the volume changes taking place upon electrochemical cycling. A Si electrode displaying a controlled porosity could circumvent the difficulty. In this perspective, we present a preparative method that yields ordered arrays of electrochemically competent silicon ...
