Abstract
Opioids such as heroin, fentanyl, raw opium, and morphine have become a serious threat to the world population in the recent past, due to their increasing use and abuse. The detection of these drugs in biological samples is usually carried out by spectroscopic and/or chromatographic techniques, but the need for quick, sensitive, selective, and low-cost new analytical tools has pushed the development of new methods based on selective nanosensors, able to meet these requirements. Modern sensors, which utilize "next-generation" technologies like nanotechnology, have revolutionized drug detection methods, due to easiness of use, their low cost, and their high sensitivity and reliability, allowing the detection of opioids at trace levels in raw, pharmaceutical, and biological samples (e.g. blood, urine, saliva, and other biological fluids). The peculiar characteristics of these sensors not only have allowed on-site analyses (in the field, at the crime scene, etc.) but also they are nowadays replacing the gold standard analytical methods in the laboratory, even if a proper method validation is still required. This paper reviews advances in the field of nanotechnology and nanosensors for the detection of commonly abused opioids both prescribed (i.e. codeine and morphine) and illegal narcotics (i.e. heroin and fentanyl analogues).

Abstract
Background:
Today, “drugs of abuse” pose serious social problems such as many crimes,
medical treatment costs, and economic repercussions. Several worldwide clinical laboratories use analytical
separation methods to analyze their patient samples for drugs and poisons. In this way, they
provide qualitative and quantitative data on the substances in various biological matrices (e.g., urine,
plasma or serum, saliva, and breath).
Methods:
An extensive review of the published articles indicates that the use of Capillary Electrophoresis
(CE) coupled with sensitivity enhancing methods is a very attractive area of interest in the
assay of drugs of abuse.
Results:
This review was prepared to have a comprehensive study on applications of sensitivity enhancing
methods on the determination of drugs of abuse especially from 2007 to present. The sample
preconcentration approaches almost address all methods from online preconcentration (both electrophoretic
and chromatographic-based methods) to offline preconcentration. Furthermore, detection
system modification and capillary column fabrications were investigated in order to increase the detection
sensitivity of complex samples in CE.
Conclusion:
The present review summarizes the most recent developments in the detection of drugs
of abuse using CE. Although CE still has a limitation in sensitive detection, several publications in
recent years have proposed valuable methods to overcome this problem.

Abstract
We developed the effect of titanium dioxide nanoparticles (nano-TiO2) on the bioaccumulation and biotransformation of arsenic (As), which remain largely unknown. We thus exposed two freshwater algae (Microcystis aeruginosa and Scenedesmus obliquus) to inorganic As with the aim of increasing our understanding on As bioaccumulation and methylation in the presence of nano-TiO2. Direct evidence of TEM and EDX image showed that nano-TiO2 (anatase) entered the exposed algae. Thus, nano-TiO2 as carriers boosted arsenic accumulation and methylation in these two algae species, which varied with both inorganic As speciation and algae species. Specifically, nano-TiO2 could enhance markedly arsenate accumulation in M. aerugginosa and arsenite accumulation in S. obliquus. Similarly, we found higher content of As methylation in M. aeruginosa of arsenite with 2 mg L−1 of nano-TiO2 treatment and in S. obliquus of arsenate treatment. Additionally, S. obliquus exhibited higher As methylation compared to M. aeruginosa, being more sensitive to As associated with nano-TiO2 than M. aeruginosa. Due to changes in pH levels inside these exposed algae, the As dissociation from nano-TiO2 inside algal cell enhanced As methylation. Accordingly, the potential influence of nanoparticles on the bioaccumulation and biotransformation of their co-contaminants deserves more attention. Nano-TiO2 entry is assumed to promote As accumulation into exposed algae. Nano-TiO2 had different carrying capacities for different forms of As and algae. As dissociation from nano-TiO2 is assumed to enhance As methylation in algae.

Abstract
Carbon nanotubes (CNTs) possess unique mechanical, physical, electrical and absorbability properties coupled with their nanometer dimensional scale that renders them extremely valuable for applications in many fields including nanotechnology and chromatographic separation. The aim of this review is to provide an updated overview about the applications of CNTs in chiral and achiral separations of pharmaceuticals, biologics and chemicals. Chiral single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) have been directly applied for the enantioseparation of pharmaceuticals and biologicals by using them as stationary or pseudostationary phases in chromatographic separation techniques such as high-performance liquid chromatography (HPLC), capillary electrophoresis (CE) and gas chromatography (GC). Achiral MWCNTs have been used for achiral separations as efficient sorbent objects in solid-phase extraction techniques of biochemicals and drugs. Achiral SWCNTs have been applied in achiral separation of biological samples. Achiral SWCNTs and MWCNTs have been also successfully used to separate achiral mixtures of pharmaceuticals and chemicals. Collectively, functionalized CNTs have been indirectly applied in separation science by enhancing the enantioseparation of different chiral selectors whereas non-functionalized CNTs have shown efficient capabilities for chiral separations by using techniques such as encapsulation or immobilization in polymer monolithic columns.

Abstract
Capillary electrophoresis (CE) is one of the most powerful techniques for the separation of biomolecules. However, the separation efficiency of proteins in CE is often compromised by their tendency to interact with the silanol groups on the surface of the inner capillary and by an uncontrolled electroosmotic flow. Herein, we report on the use of novel hydrophilic polymeric coatings that can modulate the properties of the capillary walls. The novelty of these poly(N,N-dimethylacrylamide)-based copolymers relies on the simultaneous presence of chemically reactive groups (N-acryloyloxysuccinimide and glycidyl methacrylate) and silane groups in the backbone, which results in highly stable films due to the covalent reaction between the polymer and the glass silanols. A careful optimization of monomer concentration confers anti-fouling properties to the polymer coatings, and thus allows for highly efficient acidic and alkaline protein separations. Furthermore, the presence of these monomers makes it possible to modulate the electroosmotic flow from negligible to reduced values, depending on the desired application.

Abstract
A new method for the fabrication of covalently cross-linked capillary coatings of poly(ethylene glycol) (PEG) is described using diazotized PEG (diazo-PEG) as a new photosensitive coating agent. The film of diazo-PEG depends on ionic bonding and was first prepared on the inner surface of capillary by self-assembly, and ionic bonding was converted into covalent bonding after reaction of ultraviolet light with diazo groups through unique photochemical reaction. The covalently bonded coating impedance adsorption of protein on the central surface of capillary and hence the four proteins ribonuclease A, cytochrome c, bovine serum albumin, and lysosome can be baseline separated by using capillary electrophoresis (CE). The covalently cross-linked diazo-PEG capillary column coatings not only improved the CE separation performance for proteins compared to non-covalently cross-linked coatings or bare capillary but also showed a remarkable chemical solidity and repeatability. Because photosensitive diazo-PEG took the place of the highly noxious and silane moisture-sensitive coating reagents in the fabrication of covalent coating, this technique shows the advantage of being environment-friendly and having a high efficiency for CE to make the covalently bonded capillaries.

Abstract
Dynorphin A (Dyn A) is an endogenous opioid peptide found in blood and central nervous system tissue at very low concentrations. Elevated levels of Dyn A due to different disease states, for example neurodegenerative disease, have been linked to toxic nonopioid activity. CE is a powerful technique that can achieve high-efficiency separations of charged analytes. However, CE has limited use for the analysis of basic proteins and peptides, due to their adsorption onto the inner surface of the fused silica at pHs below their pI. This adsorption can lead to a loss of efficiency, irreproducibility of migration times, and peak tailing. To obviate this problem, a polydiallyldimethylammonium chloride-stabilized gold nanoparticle-coated capillary was investigated for the separation of dynorphin metabolites. The positively charged gold nanoparticles (GNP) minimized unwanted adsorption of the positively charged peptides onto the surface of the fused-silica capillary. Separation efficiency and resolution for opioid peptides Dyn A (1-6), Dyn A (1-7), Dyn A (1-8), Dyn A (1-11), and leu-enkephalin on the GNP-coated capillary column were evaluated under different experimental parameters. The best separation of Dyn A (1-17) and its fragments was achieved using a BGE that consists of 40 mM sodium acetate buffer (pH 5) containing 5% GNP, a field strength of -306 V/cm, and a 75 μm id capillary. The developed method was applied to the separation of tryptic peptide fragments of dynorphin A (1-17).

Abstract
In this work, a CE method with bare gold nanorods (GNRs) based pseudostationary phase was developed and applied for the separation of chondroitin sulfate (CS) isomers, CS, and dermatan sulfate (DS). The separation efficiency was investigated by varying the experimental parameters such as concentration and pH of the BGE, separation voltage, internal diameter of capillary, different size, and morphology of gold nanomaterials. Results showed that different size and morphology of gold nanomaterials had different effects on the separation of CS and DS. The best separation of CS and DS was achieved in the BGE composed of aqueous 150 mmol/L (mM) ethylenediamine + 20 mM sodium dihydrogen phosphate + 30% v/v GNRs, pH 4.5, at the separation voltage of -10 kV. Capillary was 59.2 cm in length (effective length 49 cm), 50 μm id capillary thermostated at 25°C. CE with bare GNRs used as pseudostationary phase was shown to be a suitable technique for the separation of CS and DS mixtures with wider peaks. RSD of migration time and peak area of CS and DS were 0.13, 0.14 and 0.86, 1.07%, respectively.

Abstract
A novel method for the preparation of covalently linked capillary coatings of PVA was demonstrated using photosensitive diazoresin (DR) as coupling agents. Layer-by-layer self-assembly film of DR and PVA based on hydrogen bonding was first fabricated on the inner wall of capillary, then the hydrogen bonding was converted into covalent bonding after treatment with UV light through the unique photochemistry reaction of DR. The covalently bonded coatings suppressed basic protein adsorption on the inner surface of capillary, and thus a baseline separation of lysozyme, cytochrome c and BSA was achieved using CE. Compared with bare capillary or noncovalently bonded DR/PVA coatings, the covalently linked DR/PVA capillary coatings not only improved the CE separation performance for proteins, but also exhibited good stability and repeatability. Due to the replacement of highly toxic and moisture-sensitive silane coupling agent by DR in the covalent coating preparation, this method may provide a green and easy way to make the covalently coated capillaries for CE.

Abstract
Electrically driven separations which contain nanoparticles offer detection and separation advantages but are often difficult to reproduce. To address possible sources of separation inconsistencies, anionic functionalized gold nanoparticles are thoroughly characterized and subsequently included in continuous full filling capillary electrophoresis separations of varying concentrations of three small molecules. Citrate stabilized gold nanospheres are functionalized with 11-mercaptoundecanoic acid, 6-mercaptohexanoic acid, or thioctic acid self-assembled monolayers (SAMs) and characterized using dynamic light scattering, extinction spectroscopy, zeta potential, and X-ray photoelectron spectroscopy prior to use in capillary electrophoresis. Several important trends are noted. First, the stability of these anionic nanoparticles in the capillary improves with increased ligand packing density as indicated by a ratio of absorbance collected at 520 to 600 nm. Second, increasing nanoparticle concentration from 0 to 2 nM (0-0.002(5)%, w/w) minimally impacts analyte migration times; however, when higher nanoparticle concentrations are included within the capillary, nanoparticle aggregation occurs which induces separation inconsistencies. Third, analyte peak areas are most significantly impacted as their concentration decreases. These trends are attributed to both sample enrichment and electrostatic interactions between the anionic carboxylic acid functionalized gold nanoparticles and sample. These important findings suggest that sample concentration-induced conductivity differences between the sample matrix and separation buffer as well as SAM packing density are important parameters to both characterize and consider when nanoparticles are used during continuous full filling separations and their subsequent use to enhance spectroscopic signals to improve in-capillary analyte detection limits.

Abstract
Jasmonic acid (JA), an essential plant hormone controlling the plant defense signaling system and developmental processes, has stereospecific bioactivities that have not been well understood mainly due to the limitation in separation and detection methodologies. In this work, a fast CE-UV method based on short-end injection technique and a sensitive CE-QTOF-MS method based on partial filling technique were successfully developed for the enantioseparation of racemic JA. The successive coating technique was also involved by modifying the capillary with multiple ionic polymer layers of polybrene-dextran sulfate-polybrene. This was the first report on the direct resolution of both pairs of JA enantiomers, including two naturally occurring JA stereoisomers. Although no pure JA stereoisomers were commercially available, all the separated JA stereoisomers were identified indirectly by comparing the difference between the racemic standard and plant samples based on the presence and the ratio of each stereoisomer. Satisfactory results were obtained in terms of sensitivity (LOD, 24 ng/mL or 0.7 fmol for single JA stereoisomer) using 45 mmol/L ammonium acetate at pH 4.5 containing 70 mmol/L α-CD as the buffer system. This established CE-QTOF-MS method was later successfully applied for the study of the naturally occurring JA stereoisomers in wounded tobacco leaves.

Abstract
A simple, rapid and sensitive CE-ESI-MS method for the simultaneous analysis of seven stimulants and narcotics (amphetamine, ephedrine, methadone, pethidine, tetracaine, codeine and heroin) was developed. The CE-ESI-MS experimental conditions were optimized as follows: 20 mmol/L ammonium acetate with pH 9.0 as running buffer, the separation voltage of 22 kV and the sheath liquid of isopropanol/water (1:1 v/v) containing 7.5 mmol/L acetic acid with 3.0 μL/min flow rate. Under the optimized conditions, the stimulants and narcotics were well separated within 4.6 min using a 70-cm length fused-silica capillary (50 μm id). The detection limits (S/N=3) of the CE-ESI-MS analysis were in the range of 0.40-1.0 ng/mL. Method repeatability of intra-day and inter-day was satisfactory. The recoveries obtained from the analysis of spiked urine samples were between 84.1 and 108%. The developed method was successfully applied for the simultaneous analysis of methadone, pethidine and codeine and their in vitro metabolites.
