"Self-repairing" nanoshell for cell protection.

Self-repair is nature's way of protecting living organisms. However, most single cells are inherently less capable of self-repairing, which greatly limits their wide applications. Here, we present a self-assembly approach to create a nanoshell around the cell surface using nanoporous biohybrid aggregates.

Amino acid-based biohybrids for nano-shellization of individual desulfurizing bacteria.

Amino acid-based biohybrids have been developed to self-assemble on the surface of desulfurizing bacteria to form nanothin and nanoporous shells. The shells not only endow the encapsulated cells with reusability, but also offer platforms to incorporate titania and magnetic nanoparticles to improve the desulfurizing activity and the separation efficiency.

Comparative analysis of essential components between the herbal pair - and its single herbs by GC-MS combined with a chemometric resolution method.

Comparative analysis of essential components in the herbal pair Radix Saposhnikoviae-Rhizoma seu Radix Notopterygii and its single herbs is performed using two-dimensional gas chromatography-mass spectrometry data coupled with a chemometric method, named alternative moving window factor analysis. Identification of the compounds is also assisted by comparison of temperature-programmed retention indices (PTRIs) on the OV-1 column with authentic samples. The experimental results show that the main volatile chemical components in the herbal pair are mainly from Rhizoma seu Radix Notopterygii, and the number of essential chemical components in the herbal pair is almost equal to the sum of the number in the two single herbs but with a different quantity.
