Alisa Becker from the University of Melbourne tells us about recent developments in which drugs are entrapped using layer-by-layer assembly of polymers that results in a thin multilayered film. 2010-07-29T16:43:00Z http://www.materialsviews.com/details/news/760189/Enzymatic_Moonshine_Development_of_Artificial_Selenoenzymes.html Enzymes are highly efficient biocatalysts that are essential for metabolism. The development of artificial enzymes, which mimic the functionality of their natural counterparts is the focus of much research attention. 2010-07-15T18:42:00Z http://www.materialsviews.com/details/news/760153/Hydrogel_Scaffolds_for_3D_Cell_Culture.html Use of RAD-16 peptide hydrogel as a biocompatible scaffold for cartilage engineering is presented, and the biomaterial is shown to be a promising candidate. 2010-07-15T14:32:00Z http://www.materialsviews.com/details/news/759101/Smaller_and_Sharper.html Nanoscale metal–organic frameworks have been developed for use as MRI contrast agents 2010-07-13T15:48:00Z http://www.materialsviews.com/details/news/758801/Nanoparticles_Shrink_Tumours_in_Mice.html Porous silica nanoparticles loaded with anticancer drugs are effective in killing tumours 2010-07-12T12:32:00Z http://www.materialsviews.com/details/news/758051/Adipose_Tissue_Engineering_Making_Fat.html Reconstructive surgery to treat burns and other disfiguring injuries, conditions, and procedures relies on adipose tissue engineering to be successful. A new hybrid biomaterial system could be used to improve the outcome of future reconstructive treatment. 2010-07-08T14:57:00Z
