Microneedle Patch Make a Record as it Delivers Vaccine

Dec-20-19 A microneedle patch that delivers a quantum tattoo at the same time as a vaccination could help track vaccinated patients to save medication and time.

The team at MIT developed the ‘tattooing’ patch to make it easier to create and access a person’s vaccination record, particularly in developing countries. The system relies on a dye containing tiny quantum dots of semiconducting crystal that reflect specific wavelengths of light to mark different vaccines. The pattern is not visible to the naked eye, but a specially designed smartphone can be used to scan the skin and identify which vaccines have been administered.

According to MIT professor Robert Langer, “It’s possible someday that this ‘invisible’ approach could create new possibilities for data storage, biosensing, and vaccine applications that could improve how medical care is provided, particularly in the developing world.”
