The author regrets that a citation meant to be included in the Reference list was instead incorporated into the text itself.
The sixth paragraph of the article should read:
“Fortunately, advances in technology offer solutions to the issues of both cost and scarcity. Using standard consumer 3D-printers, my team and I were able to generate and assemble 1000 durable, re-wearable, high-filtration respirators with a cost in materials of only approximately $1−2 each, we distributed the 3d printed respirators to the homeless in Miami.7
Printed out of cheap polylactic acid or thermoplastic polyurethane and secured firmly with elastic straps fastened with a proprietary plastic backplate, these respirators used high-efficiency particulate air filters comparable to those used in N95s. In recently published research in The American Journal of Medicine
, we established via fit testing trials employing a particle counter that these masks offered a superior fit factor to even N95s and were more likely to fit a large variety of face shapes and sizes.8
Accordingly, the numbering of the citations should be re-ordered as follows:
