1. A handheld Surface-Enhanced Raman Spectroscopy (SERS) device for detecting phenylalanine (Phe) in a sample collected from a subject, the device comprising:
a laser generator configured to produce a laser beam;
a nanoporous anodic aluminum oxide (NAAO) substrate configured to receive the sample collected from the subject; wherein the laser beam reaches the sample on the NAAO substrate and is reflected or deflected to produce a light signal; and
a light sensor configured to receive the light signal reflected or deflected from the sample;
wherein the device is handheld and detects the Phe in the sample;
wherein the NAAO substrate comprises a multilayered nanoporous aluminum layer.
