With their high-resolution and capability to image under aqueous solution, AFM is applied to investigate the structure of biomolecules and biological process in real time. From visualization of DNA and IgG to DNA transcription, the advances in sample preparation methods have made these events come true. In addition, AFM can be used in molecular recognition. This article illustrates these major achievements of AFM in biological studies.展开更多

The ordered structure arranged by the uniform pores and the pore-pore interconnectivity through the window channel is confirmed by SEM characterization. UV-Vis-near IR absorption experiment result reveals that the wavelength at the stop band peak is tunable within the whole visible spectrum via simply altering some parameters such as pH value and light incidence angle. This finding allows to design frequency-tunable photonic band gap materials.展开更多
