Abstract
The separation and detection of multi-component mixtures has always been a challenging task. Traditional detection methods often suffer from complex operation, high cost, and low sensitivity. Surface enhanced Raman scattering (SERS) technique is a high sensitivity, powerful and rapid detection tool, which can realize the specific detection of single substance components, but it must solve the problem that multi-component mixtures cannot be accurately determined. Thin layer chromatography (TLC) technology, as a high-throughput separation technology, uses chromatographic plate as the stationary phase, and could select different developing phases for separation experiments. The advantages of TLC technology in short distance and rapid separation are widely used in protein, dye and biomedical fields. However, TLC technology has limitations in detection ability and difficulty in obtaining ideal signal intensity. The combination of TLC technology and SERS technology made the operation procedure simple and the sample size small, which can achieve rapid on-site separation and quantitative detection of mixtures. Due to the rapid development of TLC-SERS technology, it has been widely used in the investigation of various complex systems. This paper reviews the application of TLC-SERS technology in food science, environmental pollution and biomedicine.

Simultaneous determination of 14 bioactive citrus flavonoids using thin-layer chromatography combined with surface enhanced Raman spectroscopy. Food Chem 2020; 338:128115.

Abstract
Citrus flavonoids consist of diverse analogs and possess various health-promoting effects dramatically depending on their chemical structures. Since different flavonoids usually co-exist in real samples, it's necessary to develop rapid and efficient methods for simultaneous determination of multiple flavonoids. Thin layer chromatography combined with surface enhanced Raman spectroscopy (TLC-SERS) was established to simultaneously separate and detect 14 citrus flavonoids for the first time. These target compounds could be characterized and discriminated when paired with SERS at 6-500 times greater the sensitivity than TLC alone. TLC-SERS exhibited high recovery rates (91.5-121.7%) with relative standard deviation lower than 20.8%. Moreover, the established TLC-SERS method was successfully used to simultaneously detect multiple flavonoids in real samples, which exhibited comparable accuracy to high performance liquid chromatography with shorter analytical time (10 vs 45 min). All the results demonstrated that this could be a promising method for simultaneous, rapid, sensitive and accurate detection of flavonoids.

Abstract
AbstractTwelve novel aminoalkyl derivatives 3a-3f, 4a-4f and four novel amino acid derivatives 5a, 5b, 6a and 6b of polymethoxyflavones 1 and 2 were synthesized through regioselective demethylation, etherification, amination, EDCl-mediated amide condensation and alkaline hydrolysis, using tangeretin and nobiletin as starting materials. Their antiproliferative activities against four different human cancer cell lines (Aspc-1, SUN5, HepG-2 and HCT116) were evaluated by in vitro CCK-8 assay. The results show that the majority of the synthetic compounds exhibited moderate to good antiproliferative activity. In particular, the antiproliferative activity of compound 5b against HepG-2 cells (IC50 0.057 μM) was equal to the positive control drug Staurosporine (IC50 0.0575 μM).

Abstract
Lung cancer remains the leading cause of cancer associated deaths worldwide. Recent efforts have been focused on combinational and nanoparticulate therapies that can efficiently deliver multiple therapeutics. Herein, we reported cetuximab (CET) functionalized, paclitaxel (PTX) and 5-Demethylnobiletin (DMN) co-loaded nanostructured lipid carriers (NLCs) (CET-PTX/DMN-NLCs). The morphology, particle size, zeta potential, stability and drug release were tested. Cellular uptake, cell viability, synergistic effects and in vivo anti-tumor effects were evaluated on human lung adenocarcinoma cells (A549 cells), human embryonic lung cells (MRC-5 cells) and A549 paclitaxel-resistant cells bearing mice models. NLCs had sizes of around 130 nm and zeta potentials of +20-30 mV. The release of drugs from NLCs was relatively fast at the first 12 h and then became slow until completion of sustained release behavior. Cells uptake of CET-PTX/DMN-NLCs (65.8%) was remarkably higher than that of PTX/DMN-NLCs (35.5%) in A549 cells. The combination treatment with PTX and DMN synergistically decreases the viability of cells than the single PTX-NLCs and DMN-NLCs. CET-PTX/DMN-NLCs exhibited the most remarkable in vivo tumor inhibition efficiency, which suspended the tumor growth from 1010.23 to 211.18 mm3 at the end of the study. The highest tumor accumulation amount and low toxicity made CET-PTX/DMN-NLCs a promising system for the synergistic combination therapy of lung cancer.

Abstract
BACKGROUND Chikungunya virus (CHIKV), a highly contagious re-emerging virus, is transmitted by infected mosquitoes. CHIKV is prevalent in tropical countries and is continuing to creep farther north into temperate areas. CHIKV is responsible for induction of chikungunya fever (CF) and severe joint stiffness with the capability of developing into bilateral and systemic arthralgia or even encephalitis. Despite the high morbidity rate, no approved antiviral drug is available. Therefore, an anti-CHIKV therapy is necessary to control this disease. In this study, we screened four flavonoids for anti-CHIKV activities: nobiletin, phlorizin, resveratrol and oxyresveratrol. METHODS We performed MTT, Viral ToxGloTM and lactate dehydrogenase (LDH) assays to assess the viability of CHIKV-infected host cells. Plaque assay and immunofluorescent assay were utilized to evaluate the levels of viral production in quantification and qualification, respectively. RESULTS We first confirmed that nobiletin can maintain the cellular survival of infected cells without inducing significant toxicity to host cells. Nobiletin suppressed virus-induced cell death and viral production. Also, the antiviral efficacy of nobiletin can last for at least 48 h during infection. More importantly, nobiletin inhibited CHIKV infection during the translation/replication stages and viral entry, making nobiletin a potential clinical antiviral agent in prophylaxis and post-exposure treatment. CONCLUSIONS In this study, our results provided a strategy to develop anti-chikungunya agents by utilizing natural compounds. Also, we believe that nobiletin can be a potential antiviral agent against CHIKV infection worthy of being further investigated as a remedial candidate in vivo.

Abstract
Nobiletin, a polymethoxyflavone mainly found in citrus fruits, have been reported to exhibit various beneficial biological activities for human health. It is an important bioactive compound in traditional Chinese medicine, Pericarpium Citri Reticulatae and Fructus Aurantii. To detect the contents of nobiletin in citrus and herb samples, we developed an indirect competitive enzyme-linked immunosorbent assay (icELISA) based on monoclonal antibodies. It possessed a median inhibition concentration (IC50) of 2.43 ± 0.19 ng/mL and a working range of 0.52-12.3 ng/mL. The assay exhibited the average recoveries of 72.5-85.3% in citrus peel, pulp and juice samples. Moreover, eleven citrus cultivars samples and four herb samples were also detected by the icELISA. The nobiletin content varied in different citrus cultivars samples and herb samples, which were confirmed by the ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS). These results indicated that the developed immunoassay was suitable for detecting nobiletin in citrus and herb samples.

Analyzing biomolecules is essential for disease diagnostics, food safety inspection, environmental monitoring and pharmaceutical development. Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for detecting biomolecules due to its high sensitivity, rapidness and specificity in identifying molecular structures. This review focuses on the SERS analysis of biomolecules originated from humans, animals, plants and microorganisms, combined with nanomaterials as SERS substrates and nanotags. Recent advances in SERS detection of target molecules were summarized with different detection strategies including label-free and label-mediated types. This comprehensive and critical summary of SERS analysis of biomolecules might help researchers from different scientific backgrounds spark new ideas and proposals.
