"trace amounts of magnetic spiral chiral molecular nanohelices (cinchonine or cinchonidine) adsorbed onto metal nanoparticles' surface during metal ion electrochemical reduction achieves spin polarization exceeding ~80%, rare in inorganic systems... when exhibit right-handedness, preferentially allow 1 direction of spin to pass, while opposite spin cannot... chiral spintronics platform, chiral magnetic nanostructure architecture... controls handedness/ number of strands (double, multiple helices)... scalable, energy-efficient spintronics"
