Electrochemical Detection and Characterization of Nanoparticles with Printed Devices

Abstract: Innovative methods to achieve the user-friendly, quick, and highly sensitive detection of nanomaterials are urgently needed. Nanomaterials have increased importance in commercial products, and there are concerns about the potential risk that they entail for the environment. In addition, detection of nanomaterials can be a highly valuable tool in many applications, such as biosensing. Electrochemical methods using disposable, low-cost, printed electrodes provide excellent analytical performance for the detectio… Show more

“…QDs are composed of different metallic semiconductors, such as, Cd, Pb, or Zn, which have a good electroactivity, and can be electrochemically detected. [ 102 ] Lin's group reported a QDs‐based EC LFA for sensitive detection of cotinine in serum. In this LFA sensor, cotinines were conjugated with QDs and capturing cotinine antibodies were immobilized on the T line.…”

“…Quantum dots (QDs) are crystalline nanoparticles that can be relevant as electrochemical detection labels in cancer biomarker assays because of the excellent electroactivity of the employed metals. 47 In a study, magnetic beads (MBs) were suspended in EDC/NHS solution and deposited on a screen-printed carbon electrode (SPCE) and HER-2 analyte solution was added to this modified electrode. Finally, the QD solution was immobilized on MBs/SPCE.…”

“…In some cases, the molecules surrounding AgNPs could prevent electron transfer between AgNPs and the electrode. Thus, the digestion pathway is followed for the detection 114 . It is based on digesting AgNPs into Ag + using a strong oxidant.…”
