TL;DR: This new protocol for creating an AOI in a microfluidic gut-on-a-chip may enable to demonstrate the key physiological interactions of obligate anaerobic gut microbiome with the host cells associated with intestinal metabolism, homeostasis, and immune regulation.

TL;DR: It is shown that PtAu and PdAu random alloy dendrimer-encapsulated nanoparticles have different catalytic activity trends for allyl alcohol hydrogenation, and these results have significant implications for predicting the catalytic performance of bimetallic nanoparticles on the basis of density functional theory calculations.

TL;DR: This work describes a general route for identifying selective substrates that can be used to understand the differential roles of members of the deacetylase enzyme family in complex biological processes and avoids perturbation of enzyme activity that has plagued fluorescence-based assays.

TL;DR: It is demonstrated the feasible use of Pt nanoparticles encapsulated inside amine-terminated fourth-generation polyamidoamine dendrimers as peroxidase-mimetic labels for sensitive colorimetric assays.

TL;DR: Highly enhanced stable electrogenerated chemiluminescence (ECL) of Ru(bpy)3(2+) with tripropylamine (TPrA) coreactant on indium tin oxide (ITO) electrodes modified with amine-terminated dendrimers encapsulating catalytic nanoparticles while maintaining optical transparency of ITO and feasibility of the modified ITOs to sensitive ECL-based assays is reported.
