FIG 2.

Nanomechanics data of heat-treated T7 phages. Red and blue indicate indentation and retraction half-cycles, respectively. (a) Representative force versus indentation curve measured on a T7 phage particle that has been exposed to a temperature of 65°C for 15 min. (b) Data set containing 45 similar, overlaid force versus indentation curves collected in independent experiments on different phage particles heat-treated at 65°C. (c) Representative force versus indentation curve measured on a T7 phage particle that has been exposed to a temperature of 80°C for 15 min. (d) Data set containing 41 similar, overlaid force versus indentation curves collected in independent experiments on different phage particles heat treated at 80°C.
