A DNAzyme-mediated signal amplification biosensor for ultrasensitive detection of lead ions based on SERS tags

Abstract

The accumulation of trace heavy metals in the human body can be extremely damaging. Especially in the rapidly developing modern industrial society, heavy metal pollutants in the water environment are...

SERS-based microdevices for use as in vitro diagnostic biosensors

“…However, further research is required to assess SERS spectroscopy sensitivity and specificity for bioassays and optimize the technique for practical use in clinical settings. Additionally, 2D materials [52][53][54][55][56][57][58] and magnetic materials [59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74] have been introduced as efficient SERS nanotags (Fig. 2).…”

Challenges and opportunities for SERS in the infrared: materials and methods

“…224 While this procedure was originally established for the fabrication of nanoflares, 224,225 it has been seamlessly transferred to analogous systems such as SERS nanotags. 226,227…”

“…224 While this procedure was originally established for the fabrication of nanoares, 224,225 it has been seamlessly transferred to analogous systems such as SERS nanotags. 226,227 The systems described so far all make use of nanostars as the plasmonic component of the nanotag. This is because control of the hotspots formation via the use of intrinsic features such as nanostars branches is the preferred way of creating them in these analytical systems.…”
