Nanoencapsulation of pesticide atrazine improves efficacy. However, this study discovered adverse bioreactivity in alveolar type 1 epithelial cells (a major recipient inhaled nano-sized particles), following exposure to nanoencapsulated atrazine.

A DNA capsule fitted with aptamer controlled target sensing has been "woven" using a 7308-base single-stranded DNA "thread" and 196 staple oligonucleotides. The capsule enables logic-gated molecular cargo delivery to targeted cell surfaces.

Currently, hepatitis B virus (HBV), upon attaching to human hepatocytes, is considered to interact first with heparan sulfate proteoglycan (HSPG) via an antigenic loop of HBV envelope S protein. Then, it is promptly transferred to the sodium taurocholate cotransporting polypeptide (NTCP) via the myristoylated N-terminal sequence of pre-S1 region (from Gly-2 to Gly-48, HBV genotype D), and it fi...

A facile strategy was developed here to prepare cross-linked polymeric nanocapsules (CP nanocapsules) with silica nanoparticles as templates. The silica nanoparticle@cross-linked polymer nanoparticles were prepared by the encapsulation of the silica nanoparticles by the one-pot approach via surface-initiated atom transfer radical polymerization of hydroxyethyl acrylate in the presence of N,N'-m...
