intended to detect the presence of a target biomarker in a clinical
fluid. The benefits of LFA biosensors include short times to obtain test
results, a user-friendly format, low cost, and long-term stability.
However, they possess major limitations in terms of quantitative
analysis and detection sensitivity. To resolve these problems, many
different types of optical readers in combination with a LFA strip for
the detection of fluorescence, chemi-luminescence and electrochemical
signals have been employed but they still suffer from poor sensitivity
and low precision. Our research group recently developed several
different types of surface-enhanced Raman scattering (SERS)-based assay
platforms for the highly sensitive biomarker detection [1-3]. We
believe that our proposed SERS-based assay platforms, which possess both
high sensitivity and quantitative evaluation capability, show
significant potential for the rapid and sensitive detection of target
markers in a simplified manner. In this presentation, the current
advances of SERS-based assay platforms and their application potential
in biomedical diagnostics and food engineering will be discussed. First,
the development of SERS-based microfluidic platforms has attracted
significant recent attention in the biomedical sciences. SERS is a
highly sensitive detection modality, with microfluidic platforms
providing many advantages over microscale methods, including high
throughput, facile automation and reduced sample requirements.
Accordingly, the integration of SERS with microfluidic platforms offers
significant utility in chemical and biological experimentation. Herein,
we report a fully integrated SERS-based microdroplet platform for the
automatic immunoassay of specific target antigens. Second, I will
present a SERS-based mapping technique for the highly sensitive and
reproducible analysis of multiple mycotoxins. Raman images of three
mycotoxins, ochratoxin A (OTA), fumonisin B (FUMB), and aflatoxin B1
(AFB1) have been obtained by rapidly scanning the SERS
nanotags-anchoring mycotoxins captured on a three-dimensional (3D)
nanopillar plasmonic substrate. This strong enhancement effect made it
possible to perform a highly sensitive detection of multiple mycotoxins.
Consequently, this made it possible to gain a highly reproducible
quantitative analysis of mycotoxins. We anticipate that these SERS-based
assay platforms provide new insights in the development of facile assay
platforms for various hazardous materials.[1] J. Choo et al.

摘要:This seminar will summarize the recent research on synthesis,
characterization and applications of two-dimensional nanomaterials
[1]. It covers the synthesis and characterization of novel
low-dimensional nanomaterials, such as graphene-based composites [2]
including the first-time synthesized hexagonal-close packed (hcp) Au
nanosheets on graphene oxide [3], surface-induced phase transformation
of AuSSs from hcp to face-centered cubic (fcc) structures [4], the
synthesis of ultrathin fcc Au@Pt and Au@Pd rhombic nanoplates through
the epitaxial growth of Pt and Pd on the hcp AuSSs, respectively
[5], and the epitaxial growth of metal and semiconductor
nanostructures on solution-processable transition metal dichalcogenide
nanoshees at ambient conditions [6], single- or few-layer metal
dichalcogenide nanosheets [7] and hybrid nanomaterials [8], the
large-amount, uniform, ultrathin metal sulfide and selenide nanocrystals
[9], other 2D nanomaterials [10], nanodots prepared from 2D
nanomaterials [11], and self-assembled 2D nanosheets [12] and chiral
nanofibers from ultrathin low-dimensional nanomaterials [13]. Later
on, the applications of these novel nanomaterials in chemical and
bio-sensors [14], solar cells [15], water splitting [16], hydrogen
evolution reaction [6, 8d,e], electric devices [17], memory devices
[18], conductive electrodes [14b, 15, 17a, 18a,b, 19], other clean
energy [20], etc will be demonstrated.
