Temp-controlled 'nanopores' may allow detailed blood analysis

to mistake one for another. So the team expanded their measurement capability by attaching gold nanoparticles to engineered nanopores, "which provides another means to discriminate between various molecular species via temperature control," Reiner says.

The team attached gold nanoparticles to the nanopore via tethers made from complementary DNA strands. Gold's ability to absorb light and quickly convert its energy to heat that conducts into the adjacent solution allows the team to alter the temperature of the nanopore with a laser at will, dynamically changing the way individual molecules interact with it.

"Historically, sudden temperature changes were used to determine the rates of chemical reactions that were previously inaccessible to measurement," says NIST biophysicist John Kasianowicz. "The ability to rapidly change temperatures in volumes commensurate with the size of single molecules will permit the separation of subtly different species. This will not only aid the detection and identification of biomarkers, it will also help develop a deeper understanding of thermodynamic and kinetic processes in single molecules."
