A stable magnetic nanocomposite of collagen and superparamagnetic iron oxide nanoparticles (SPIONs) is prepared by a simple process utilizing protein wastes from leather industry. Molecular interaction between helical collagen fibers and spherical SPIONs is proven through calorimetric, microscopic and spectroscopic techniques. This nanocomposite exhibited selective oil absorption and magnetic t...

The interface between biosystems and nanomaterials is emerging for detection of various biomolecules and subtle cellular activities. In particular, the development of cost-effective and sequence-selective DNA detection is urgent for the diagnosis of genetic or pathogenic diseases. Graphene-based nanocarbon materials, such as carbon nanotubes and thin graphene layers, have been employed as biose...

Single-walled carbon nanohorn (CNH) is a type of nanocarbon that is a single-graphene nanometer-sized pseudo tubule with a diameter of 2-5 nm and a length of 40-50 nm. About 2000 CNHs assemble to form a spherical aggregate with a diameter of about 100 nm. CNHs have low toxicity and their potential medical applications have therefore attracted much research attention. In this report, we show tha...

We coated graphitic nanocarbons by thermal chemical vapor deposition (CVD) on silicon flakes recycled from the waste of wafer manufacturing processes as an active material for anode lithium ion battery (LIB). Ferrocene contains both iron catalyst and carbon, while camphor serves additional carbon source. Water promotes catalytic growth nanocarbons, including nanotubes (CNTs), fibers (CFs), film...
