Portable Carbon Nanotube Biosensors
Mengmeng Xiao, Yuehua Ke, Zhi‐Yong Zhang, and co‐workers develop a multi‐functionalized carbon nanotube field effect transistor biosensor arrays with a portable data reading system for the on‐site single virus level detection of SARS‐CoV‐2. The biosensor arrays can detect SARS‐CoV‐2 virus antigens and the unamplified long chain RNAs simultaneously with a detection...
The rapid and sensitive detection of trace‐level viruses in a simple and reliable way is of great importance for epidemic prevention and control. Here, a multi‐functionalized floating gate carbon nanotube field effect transistor (FG‐CNT FET) based biosensor is reported for the single virus level detection of SARS‐CoV‐2 virus antigen and RNA rapidly with a portable sensing platform. The aptamers functionalized...
Epitaxial growth and controllable doping of wafer‐scale atomically thin semiconductor single crystals are two central tasks to tackle the scaling challenge of transistors. Despite considerable efforts are devoted, addressing such crucial issues simultaneously under 2D confinement is yet to be realized. Here, an ingenious strategy to synthesize record‐breaking 4 in. length Fe‐doped transition‐metal...
Inflammatory response plays an important role not only in the normal physiology but also in the pathology such as cancers. 7b, a novel naphthalimide-based DNA intercalator, has exhibited anti-inflammatory effects in phorbol12-myristate 13-acetate/phytohemagglutinin (PMA/PHA)-induced inflammatory responses of Jurkat T cells in our previous study. Here, we tried to further investigate its anti-inflammatory...
Because of small size and light mass, flip-chip bonding technology is widely used in packaging industry. The precision of bonder directly determines the quality of flip-chip. Based on theory of small displacement torsor (SDT), the tolerance model of the bonder with the thermal deformation is built. Compared with the tolerance model without thermal deformation, the influence of temperature on the bonding...
