Mechano-Bactericidal Nanopillar Surface: 2D Cross-Section

Cicada and dragonfly wings, and the nanotextured titanium coatings engineered to copy them, kill bacteria with geometry alone: a field of blunt nanopillars stretches an adhered cell's own membrane until it tears itself open, no antibiotic or toxic ion involved. This 2D companion to the 3D nanopillar array simulator keeps the exact same areal-strain and tension physics — computed independently per cell, not a flattened render of the 3D scene — but shows it as a pannable, zoomable side cross-section: a row of pillars with a membrane line that visibly sags over each bacterium as it settles, sliders for pillar spacing, pillar height, adhesion energy and baseline membrane tension all feeding the same ε(h), T(h) and overdamped-settling formulas, with live penetration-depth and membrane-tension readouts against the lysis threshold and a real burst effect when a cell's tension crosses it.
