Graphene-based biosensors for detection of bacteria and their metabolic activities
Graphene, which is a recently discovered single-atom-thick planar sheet of carbon atoms perfectly arranged in a honeycomb lattice, has great potential in biosensing owing to its extraordinary electrical, physical, ...
Ultra-sensitive and wide-dynamic-range sensors based on dense arrays of carbon nanotube tips
Electrochemical electrodes based on dense and vertically aligned arrays of multi-walled carbon nanotubes (MWCNTs) were produced. The open tips of individual hollow nanotubes are exposed as active sites while ...
Detecting metabolic activities of bacteria using a simple carbon nanotube device for high-throughput screening of anti-bacterial drugs
In this contribution, we demonstrate a simple carbon nanotube device to electrically detect the presence of bacteria (Escherichai coli) with high sensitivity (<100 cfu/mL) and the glucose triggered metabolic ...
Micro- and nanotechnologies for study of cell secretion
Cell secretion or exocytosis is a fundamental and ubiquitous cell function in which intracellular vesicles (50-100 nm in diameter) fuse with the plasma membrane and release their content into the extracellular space. ...
A graphene nanoribbon network and its biosensing application
Graphene oxide nanoribbons (GONRs) have been prepared by chemically unzipping multiwalled carbon nanotubes (MWCNTs). Thin-film networks of GONRs were fabricated by spray-coating, followed by ...
