DEFINED MICRO-THERMAL DOTS

Ideal covert barcodes for innoxious application should have small sizes, large
capacity, can be added into object without being notices and re-collected readily
for rapid readout. One particular area in need of such barcode is biobanking,
where biological samples are collected at an exponential growth rate, and error
in labeling could ruin the whole system. This article reports a new method to
label specimen in a covert, innoxious and high fidelity way by using water
insoluble polymer microdots containing magnetic nanoparticles (for easy
collection) and a panel of phase change nanoparticles (for high capacity
labeling). The lithographically generated microdots can be distributed evenly in
solution, and each of solution contains over a thousand tiny microdots, each one
has a unique identification number registered to one sample or object. The
microdots are non-toxic, stable in solution without losing particles for a long
term of time, and can be transferred together with sample, re-collected with
magnet, and decoded with differential scanning calorimetry.
