Hydrogel porosity controlling DNA-directed immobilization of gold nanoparticles revealed by DNA melting and scanning helium ion microscopy
(Royal Society of Chemistry, 2012-04-07)Immobilization of nanomaterials is important for many applications, including sensor development, biomaterials design and catalysis. DNA-directed immobilization has been widely used because of its high specificity and ... -
Visual detection of lead(II) using a label-free DNA-based sensor and its immobilization within a monolithic hydrogel
(Royal Society of Chemistry, 2012-02-07)Lead is highly toxic and its detection has attracted a lot of research interests. In recent years, DNA has been used for Pb2+ recognition and many fluorescent sensors with low to sub-nM detection limits have been reported. ...
