Abstract
Layered double hydroxides (LDHs) have attracted considerable attention as promising materials for electrochemical and optical sensors owing to their excellent catalytic properties, facile synthesis strategies, highly tunable morphology, and versatile hosting ability. LDH-based electrochemical sensors are affordable alternatives to traditional precious-metal-based sensors, as LDHs can be synthesized from abundant inorganic precursors. LDH-modified probes can directly catalyze or host catalytic compounds that facilitate analyte redox reactions, detected as changes in the probe's current, voltage, or resistance. The porous and lamellar structure of LDHs allows rapid analyte diffusion and abundant active sites for enhanced sensor sensitivity. LDHs can be composed of conductive materials such as reduced graphene oxide (rGO) or metal nanoparticles for improved catalytic activity and analyte selectivity. As optical sensors, LDHs provide a spacious, stable structure for synergistic guest-host interactions. LDHs can immobilize fluorophores, chemiluminescence reactants, and other spectroscopically active materials to reduce the aggregation and dissolution of the embedded sensor molecules, yielding enhanced optical responses and increased probe reusability. This review discusses standard LDH synthesis methods and overviews the different electrochemical and optical analysis techniques. Furthermore, the designs and modifications of exemplary LDHs and LDH composite materials are analyzed, focusing on the analytical performance of LDH-based sensors for key biomarkers and pollutants, including glucose, dopamine (DA), H2O2, metal ions, nitrogen-based toxins, and other organic compounds.

Abstract
Background:
Electroanalytical techniques play a very important role in the areas of medicinal,
clinical as well as pharmaceutical research. Amongst these techniques, the voltammetric methods
for the determination of drugs using nanomaterials based chemically modified electrodes (CMEs)
have received enormous attention in recent years. This is due to the sensitivity and selectivity they
provide on qualitative as well as quantitative aspects of the electroactive analyte under study. The aim
of the present review was to discuss the work on nanomaterials based CMEs for the analysis of drugs
covering the period from 2000 to present employing various voltammetric techniques for different
classes of the drugs.
Methods:
The present review deals with the determination of different classes of drugs including analgesics,
anthelmentic, anti-TB, cardiovascular, antipsychotics and anti-allergic, antibiotic and gastrointestinal
drugs. Also, a special section is devoted for enantioanalysis of certain chiral drugs using
voltammetry. The detailed information of the voltammetric determination for the drugs from each
class employing various techniques such as differential pulse voltammetry, cyclic voltammetry, linear
sweep voltammetry, square wave voltammetry, stripping voltammetry, etc. are presented in tabular
form below the description of each class in the review.
Results:
Various nanomaterials including carbon nanotubes, graphene, carbon nanofibers, quantum
dots, metal/metal oxide nanoparticles, polymer based nanocomposites have been used by researchers
for the development of CMEs over a period of time. The large surface area to volume ratio, high conductivity,
electrocatalytic activity and biocompatibility make them ideal modifiers where they produce
synergistic effect which helps in trace level determination of pharmaceutical, biomedical and medicinal
compounds. In addition, macrocyclic compounds as chiral selectors have been used for the determination
of enantiomeric drugs where one of the isomers captured in the cavities of chiral selector
shows stronger binding interaction for one of the enantiomorphs.
Conclusion:
arious kinds of functional nanocomposites have led to the manipulation of peak potential
due to drug - nanoparticles interaction at the modified electrode surface. This has facilitated the
simultaneous determination of drugs with almost similar peak potentials. Also, it leads to the enhancement
in voltammetric response of the analytes. It is expected that such modified electrodes can
be easily miniaturized and used as portable, wearable and user friendly devices. This will pave a way
for in-vivo onsite real monitoring of single as well as multi component pharmaceutical compounds.

[PMID: 30219721 DOI: 10.1016/j.bios.2018.08.029] [Citation(s) in RCA: 112] [Impact Index Per Article: 18.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 08/11/2018] [Accepted: 08/13/2018] [Indexed: 12/31/2022]
Abstract
Nanomaterial-embedded sensors have been developed and applied to monitor various targets. Mycotoxins are fungal secondary metabolites that can exert carcinogenic, mutagenic, teratogenic, immunotoxic, and estrogenic effects on humans and animals. Consequently, the need for the proper regulation on foodstuff and feed materials has been recognized from times long past. This review provides an overview of recent developments in electrochemical sensors and biosensors employed for the detection of mycotoxins. Basic aspects of the toxicity of mycotoxins and the implications of their detection are comprehensively discussed. Furthermore, the development of different molecular recognition elements and nanomaterials required for the detection of mycotoxins (such as portable biosensing systems for point-of-care analysis) is described. The current capabilities, limitations, and future challenges in mycotoxin detection and analysis are also addressed.
