Patterned Superhydrophobic SERS Substrates for Sample Pre-Concentration and Demonstration of Its Utility through Monitoring of Inhibitory Effects of Paraoxon and Carbaryl on AChE. Molecules 2020; 25:E2223. [PMID: 32397331 PMCID: PMC7248789 DOI: 10.3390/molecules25092223] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 04/28/2020] [Accepted: 05/06/2020] [Indexed: 12/16/2022] Open
Abstract
We describe a patterned surface-enhanced Raman spectroscopy (SERS) substrate with the ability to pre-concentrate target molecules. A surface-adsorbed nanosphere monolayer can serve two different functions. First, it can be made into a SERS platform when covered by silver. Alternatively, it can be fashioned into a superhydrophobic surface when coated with a hydrophobic molecular species such as decyltrimethoxy silane (DCTMS). Thus, if silver is patterned onto a latter type of substrate, a SERS spot surrounded by a superhydrophobic surface can be prepared. When an aqueous sample is placed on it and allowed to dry, target molecules in the sample become pre-concentrated. We demonstrate the utility of the patterned SERS substrate by evaluating the effects of inhibitors to acetylcholinesterase (AChE). AChE is a popular target for drugs and pesticides because it plays a critical role in nerve signal transduction. We monitored the enzymatic activity of AChE through the SERS spectrum of thiocholine (TC), the end product from acetylthiocholine (ATC). Inhibitory effects of paraoxon and carbaryl on AChE were evaluated from the TC peak intensity. We show that the patterned SERS substrate can reduce both the necessary volumes and concentrations of the enzyme and substrate by a few orders of magnitude in comparison to a non-patterned SERS substrate and the conventional colorimetric method.

Abstract
The emergence of synthetic glycoconjugates as chemical probes for the detection of glycosidase enzymes has resulted in the development of a range of useful chemical tools with applications in glycobiology, biotechnology, medical and industrial research. Critical to the function of these probes is the preparation of substrates containing a glycosidic linkage that when activated by a specific enzyme or group of enzymes, irreversibly releases a reporter molecule that can be detected. Starting from the earliest examples of colourimetric probes, increasingly sensitive and sophisticated substrates have been reported. In this review we present an overview of the recent advances in this field, covering an array of strategies including chromogenic and fluorogenic substrates, lanthanide complexes, gels and nanoparticles. The applications of these substrates for the detection of various glycosidases and the scope and limitations for each approach are discussed.

Abstract
The ability to develop new and sensitive methods of biomolecule detection is crucial to the advancement of pre-clinical disease diagnosis and effective patient specific treatment. Surface enhanced Raman scattering (SERS) is an optical spectroscopy amenable to this goal, as it is capable of extremely sensitive biomolecule detection and multiplexed analysis. This perspective highlights where SERS has been successfully used to detect target biomolecules, specifically DNA and proteins, and where in vivo analysis has been successfully utilised. The future of SERS development is discussed and emphasis is placed on the steps required to transport this novel technique from the research laboratory to a clinical setting for medical diagnostics.

Abstract
Cyclodepsipeptides of the enniation-, PF1022-, and verticilide-family represent a diverse class of highly interesting natural products with respect to their manifold biological activities. However, until now no stepwise solid-phase synthesis has been accomplished due to the difficult combination of N-methyl amino acids and hydroxycarboxylic acids. We report here the first stepwise solid-phase synthesis of the anthelmintic cyclooctadepsipeptide PF1022A based on an Fmoc/THP-ether protecting group strategy on Wang-resin. The standard conditions of our synthesis allow an unproblematic adaption to an automated peptide synthesizer.

Abstract
The gold standard for clinical diagnostics of tissues is immunofluorescence staining. Toxicity of many fluorescent dyes precludes their application in vivo. Raman spectroscopy, a chemically specific, label-free diagnostic technique, is rapidly gaining acceptance as a powerful alternative. It has the ability to probe the chemical composition of biological materials in a non-destructive and mostly non-perturbing manner. We review the most recent developments in Raman spectroscopy in the life sciences, detailing advances in technology that have improved the ability to screen for diseases. Its role in the monitoring of biological function and mapping the cellular chemical microenvironment will be discussed. Applications including endoscopy, surface-enhanced Raman scattering (SERS), and coherent Raman scattering (CRS) will be reviewed.

Abstract
The preparation and use of tri-functional linkers for surface complexation to both gold and silver nanoparticles is reported. These molecules confer excellent stability towards nanoparticles ensuring particle monodispersity in biological buffers, and also incorporate dyes to allow use of the functionalised nanoparticles as SERRS reporters. Biomolecule conjugation and quantitation has been illustrated using Alexafluor 680 labelled streptavidin. Variation of the chromophore has been introduced, which allows for exquisite control of the SERRS by manipulation of laser wavelength. This demonstrates the potential of SERRS functionalised nanoparticles for multiple, simultaneous monitoring of excitation events, an area of research where the capability of molecular fluorophores and quantum dots is limited.
