Variable Falle: Kolloide aus Goldnanopartikeln mit einer Beschichtung aus Poly(N-isopropylacrylamid)-Mikrogel (pNIPAM) können Moleküle je nach Temperatur auf verschiedene Art fixieren (siehe Schema). Die poröse pNIPAM-Schale verhindert eine elektromagnetische Kopplung zwischen den Metallpartikeln, sodass bei Messungen der oberflächenverstärkten Raman-Streuung (SERS) hoch reproduzierbare Ergebnisse erhalten werden.
