A graphene oxide/silver coated polymer cladding silica fiber optical surface plasmon
resonance (SPR) human IgG detection biosensor with a high sensitivity and a low limit of …

In this study, triangular silver nanoplates (TAgNPs) with various sizes were prepared using a
seed-mediated growth method. The TAgNPs/GO and TAgNPs/rGO nanohybrids were …

Because avidin and biotin molecules exhibit the most specific and strongest non-covalent
interaction, avidin-biotin technology is widely used in ELISA (enzyme-linked immunosorbent …

A surface plasmon resonance (SPR) biosensor based on graphene oxide (GO) decorated
with gold nanorod (AuNR)–antibody conjugates was developed. Compared with traditional …

We reported the fluorescence sensor of carbon dots (CDs) synthesized for the highly
sensitive and selective detection of bilirubin in human urine. High-resolution transmission …

Surface-enhanced Raman spectroscopy (SERS) has recently emerged as an innovative tool
for therapeutic-drug monitoring (TDM), making it an ideal candidate for personalized …

New graphene–silk peptide (Gr–SP) nanosheets were prepared and successfully fabricated
with tyrosinase (Tyr) as a novel biosensor for the determination of phenolic compounds. The …

A label-free electrochemical immunosensor for sensitive detection of α-fetoprotein (AFP)
was developed based on graphene/SnO 2/Au nanocomposite. The graphene/SnO 2/Au …
