Abstract

/Ag core-shell heterojunction nanowire array with the optimal composition exhibits a PIERS enhancement factor of up to 47 times, approaching the highest reported value to date, and an extraordinarily long relaxation time of over 84 days, which is far superior to those of other material substrates. These unparalleled characteristics provide a reliable, rapid, and convenient technique for the detection of low-concentration biochemical substances.
