Focal point microenvironment

In core- (and focal point-) functionalized dendrimers, the catalyst can especially benefit from the specific microenvironment created by dendritic structures. Site-isolation effects can be beneficial for reactions that are deactivated by excess ligand, and can also prevent bimetallic deactivation pathways. 

After naphthalene (300 mg/kg i.p.) treatment of mice and epithelial repair, neuroepithelial bodies were significantly increased along the walls of the airways as well as on branch point ridges (Peake et al. 2000). Reynolds et al. (2000) provided the following evidence that the neuroepithelial body microenvironment serves as a source of airway progenitor cells that contribute for focal regeneration of the airway epithelium ...
