© 2019 American Chemical Society. Biofilms are prevalent in chronic wounds and once formed are very hard to remove, which is associated with poor outcomes and high mortality rates. Biofilms are comprised of surface-attached bacteria embedded in an ex...

Journal of materials chemistry B, Materials for biology and medicine /, 7(22), 3497-3504. https://doi.org/10.1039/c9tb00679f

We report a large scale preparation of bioimprints of layers of cultured human leukemic HL60 cells which can perform cell shape and size recognition from a mixture with peripheral blood mononuclear cells (PBMCs). We demonstrate that the bioimprint-ce... Read More about Bioimprint aided cell recognition and depletion of human leukemic HL60 cells from peripheral blood.

Dual-functionalised shellac nanocarriers give a super-boost of the antimicrobial action of berberine (2018)
