Abstract
Simultaneous detection of cancer biomarkers holds great promise for the early diagnosis of cancer. In the present work, an ultrasensitive and reliable surface-enhanced Raman scattering (SERS) sensor has been developed for simultaneous detection of multiple liver cancer related microRNA (miRNA) biomarkers. We first proposed a novel strategy for the synthesis of nanogap-based SERS nanotags by modifying gold nanoparticles (AuNPs) with thiolated DNA and nonfluorescent small encoding molecules. We also explored a simple approach to a green synthesis of hollow silver microspheres (Ag-HMSs) with bacteria as templates. On the basis of the sandwich hybridization assay, probe DNA-conjugated SERS nanotags used as SERS nanoprobes and capture DNA-conjugated Ag-HMSs used as capture substrates were developed for the detection of target miRNA with a detection limit of 10 fM. Multiplexing capability for simultaneous detection of the three liver cancer related miRNAs with the high sensitivity and specificity was demonstrated using the proposed SERS sensor. Furthermore, the practicability of the SERS sensor was supported by the successful determination of target miRNA in cancer cells. The experimental results indicated that the proposed strategy holds significant potential for multiplex detection of cancer biomarkers and offers the opportunity for future applications in clinical diagnosis.

Abstract
Electromagnetic hot spots of surface-enhanced Raman scattering have been extensively employed for bioanalysis in solution or on a substrate, but building hot spots in living systems for probing targets of interest has not been achieved yet because of the complex and dynamic physiological environment. Herein, we show that a target-programmed nanoparticle dimerization can be combined with the background-free Raman reporters (alkyne, C≡C; nitrile, C≡N) for multiplexed imaging of microRNAs (miRNAs) in living cells. The in situ formation of plasmonic dimers results in an intense hot spot, thus dramatically enhancing the Raman signals of the reporters residing in the hot spot. More significantly, the reporters exhibit single nonoverlapping peaks in the cellular Raman-silent region (1800-2800 cm-1), thus eliminating spectral unmixing and background interference. A 3D Raman mapping technique was harnessed to monitor the spatial distribution of the dimers and thus the multiple miRNAs in cells. This approach could be extended to probe other biomarkers of interest for monitoring specific pathophysiological events at the live-cell level.

Abstract
Surface-enhanced Raman scattering (SERS) spectroscopy has attracted tremendous interests as a highly sensitive label-free tool. The local field produced by the excitation of localized surface plasmon resonances (LSPRs) dominates the overall enhancement of SERS. Such an electromagnetic enhancement is unfortunately accompanied by a strong modification in the relative intensity of the original Raman spectra, which highly distorts spectral features providing chemical information. Here we propose a robust method to retrieve the fingerprint of intrinsic chemical information from the SERS spectra. The method is established based on the finding that the SERS background originates from the LSPR-modulated photoluminescence, which contains the local field information shared also by SERS. We validate this concept of retrieval of intrinsic fingerprint information in well controlled single metallic nanoantennas of varying aspect ratios. We further demonstrate its unambiguity and generality in more complicated systems of tip-enhanced Raman spectroscopy (TERS) and SERS of silver nanoaggregates.

Abstract
Optical labels are needed for probing specific target molecules in complex biological systems. As a newly emerging category of tags for molecular imaging in live cells, the Raman label attracts much attention because of the rich information obtained from targeted and untargeted molecules by detecting molecular vibrations. Here, we list three types of Raman probes based on different mechanisms: Surface Enhanced Raman Scattering (SERS) probes, bioorthogonal Raman probes, and Resonance Raman (RR) probes. We review how these Raman probes work for detecting and imaging proteins, nucleic acids, lipids, and other biomolecules in vitro, within cells, or in vivo. We also summarize recent noteworthy studies, expound on the construction of every type of Raman probe and operating principle, sum up in tables typically targeting molecules for specific binding, and provide merits, drawbacks, and future prospects for the three Raman probes.

Abstract
Multiplex bioassays have drawn more and more attention for the development of novel analytical techniques. Herein, we used photonic crystal (PC) and surface enhanced Raman scattering (SERS) as two encoding elements in different modes for the dual encoding of multiplex bioassays. In practice, PC beads and SERS nanotags act as carriers and labels, respectively, for the multiplex detection of antigens in a sandwich format. Except for the amplified capacity by two encoding modes, we also demonstrated that fine stability, low background and high sensitivity were realized for the quantitative analysis of multiple analytes, which holds great promise in biomedical applications like protein biomarker analysis.

Abstract
This paper demonstrates the direct sensing of glucose at physiologically relevant concentrations with surface-enhanced Raman spectroscopy (SERS) on gold film-over-nanosphere (AuFON) substrates functionalized with bisboronic acid receptors. The combination of selectivity in the bisboronic acid receptor and spectral resolution in the SERS data allow the sensors to resolve glucose in high backgrounds of fructose and, in combination with multivariate statistical analysis, detect glucose accurately in the 1-10 mM range. Computational modeling supports assignments of the normal modes and vibrational frequencies for the monoboronic acid base of our bisboronic acids, glucose and fructose. These results are promising for the use of bisboronic acids as receptors in SERS-based in vivo glucose monitoring sensors.

Abstract
Effective disease management strategies to prevent catastrophic crop losses require rapid, sensitive, and multiplexed detection methods for timely decision making. To address this need, a rapid, highly specific and sensitive point-of-care method for multiplex detection of plant pathogens was developed by taking advantage of surface-enhanced Raman scattering (SERS) labeled nanotags and recombinase polymerase amplification (RPA), which is a rapid isothermal amplification method with high specificity. In this study, three agriculturally important plant pathogens (Botrytis cinerea, Pseudomonas syringae, and Fusarium oxysporum) were used to demonstrate potential translation into the field. The RPA-SERS method was faster, more sensitive than polymerase chain reaction, and could detect as little as 2 copies of B. cinerea DNA. Furthermore, multiplex detection of the three pathogens was demonstrated for complex systems such as the Arabidopsis thaliana plant and commercial tomato crops. To demonstrate the potential for on-site field applications, a rapid single-tube RPA/SERS assay was further developed and successfully performed for a specific target outside of a laboratory setting.
