An immunoassay based on fully autonomous, self-propelling microengines

Table of contents imageIn this recent publication, Joseph Wang et al. report the first example of a self-propelling antibody functionalized catalytic microengine for targeting and delivering target proteins in a microfluidic device.

The microengines, 8 µm long, were prepared by a template-based electrodeposition of multilayer polymer/ Pt/ Ni microtubes.  The outermost polymer layer (PEDOT: PEDOT-COOH) facilitates the immobilization of the antibodies for biomolecular recognition, the innermost Pt layer catalyses the breakdown of the hydrogen peroxide fuel, thereby releasing oxygen bubbles that propel the microengines through the microfluidic chip.  Finally, the intermediate Ni layer is used to guide the microengines through the chip via magnetic guidance.

The authors demonstrated that the microengines could be used for the direct, real-time visualisation of antibody-protein binding events on the surface of Staphylococcus aureus bacterial cells.  The autonomous transport of antibody-functionalized microengines in a lab-on-a-chip (LOC) format allows the user to avoid laborious and time-consuming washing steps associated with conventional immunoassay protocols.  The authors envisage that the LOC self-propelling microengines could be potential tools for medical diagnostics and food safety analysis.

Filling the space

Biomineral nanoparticles are space-filling
Li Yang, Christopher E. Killian, Martin Kunz, Nobumichi Tamura and P. U. P. A. Gilbert
Nanoscale, 2011, 3, 603-609

Scientists in the US have tried to answer the question of whether biominerals are mesocrystals or not.

Sea urchin biominerals are known to form from aggregating nanoparticles of amorphous calcium carbonate, which then crystallize into macroscopic single crystals of calcite. The group measured the surface areas of these biominerals, finding them to be comparable to those of space-filling macroscopic geologic calcite crystals. These biominerals are therefore different from synthetic mesocrystals, which are always porous. Based on this results, the group proposes that space-filling amorphous calcium carbonate is the structural precursor for echinoderm biominerals.

Mollusk shells, corals, and echinoderm biominerals have remarkable mechanical properties, making them the object of many studies to shed some light on their formation mechanisms.
