Microbe Monopoly: Go Directly to Jail
• A Cell for a Cell: Using multiphoton lithography, scientists can now fabricate a 3D nanoscale isolation chamber around a single cell in just over a minute! Only 25 μm × 25 μm in length and breadth (or 0.00098 inch per side), and 10-12 μm in height, this prison cell is made of protein particles that can be photo-activated to set into a solid hydrogel. The prisoner is treated kindly, with breathable, bio-compatible windows built into the walls which allows the cell to feed and breed. Indeed, the scanning EM image on the extreme right shows the walls bulging with daughter cells that have divided and filled the chamber. Overcrowding of prisons seems to be an issue even in the cellular world, sigh .
• Targeted Traps: While current methods allow single cells to be trapped on nanopatterned surfaces, selection is random. This new method allows specific cells, such as one with a particular phenotype (or appearance), to be captured and investigated. In another word, profiling. double sigh (Enough of anthropomorphism 🙂
