“…Disposable and sensitive electrochemical detectors in HPLC systems, based on modified electrodes, could be a good alternative to develop methods meeting the above-mentioned characteristics, such as those based on metal/metal oxide modified electrodes [42][43][44]. Recently the incorporation of carbon nanostructures, such as graphene nanosheets and mostly carbon nanotubes, has improved the performance of these kind of modified electrode in the determination of carbohydrates, amino acids and related compounds [45][46][47][48].…”

“…Lactate is another important biomolecule and has been widely investigated through various analytical approaches. Recently, novel nanobiosensors were fabricated based on lactate oxidase and MNP or nanohybrids to monitor lactate levels for medical diagnostic applications [57–59] and assessment of food quality [60]. …”

The aim of this review is to cover advances in noble metal nanoparticle (MNP)-based biosensors and to outline the principles and main functions of MNPs in different classes of biosensors according to the transduction methods employed. The important biorecognition elements are enzymes, antibodies, aptamers, DNA sequences, and whole cells. The main readouts are electrochemical (amperometric and voltametric), optical (surface plasmon resonance, colorimetric, chemiluminescence, photoelectrochemical, etc.) and piezoelectric. MNPs have received attention for applications in biosensing due to their fascinating properties. These properties include a large surface area that enhances biorecognizers and receptor immobilization, good ability for reaction catalysis and electron transfer, and good biocompatibility. MNPs can be used alone and in combination with other classes of nanostructures. MNP-based sensors can lead to significant signal amplification, higher sensitivity, and great improvements in the detection and quantification of biomolecules and different ions. Some recent examples of biomolecular sensors using MNPs are given, and the effects of structure, shape, and other physical properties of noble MNPs and nanohybrids in biosensor performance are discussed.

“…Table 3 shows that more than half of the listed sensors utilizing cross-linking offer a sufficient detection limit needed for fetal monitoring [ 49 , 73 , 80 , 81 , 83 , 85 , 91 , 102 , 116 , 117 , 118 ]. The response time ranging from 5 s to 180 s for the electrochemical sensors may not be entirely due to the immobilization method but could be the result of different protective layers employed, which does not allow for fast diffusion.…”

This article reviews existing clinical practices and sensor research undertaken to monitor fetal well-being during labour. Current clinical practices that include fetal heart rate monitoring and fetal scalp blood sampling are shown to be either inadequate or time-consuming. Monitoring of lactate in blood is identified as a potential alternative for intrapartum fetal monitoring due to its ability to distinguish between different types of acidosis. A literature review from a medical and technical perspective is presented to identify the current advancements in the field of lactate sensors for this application. It is concluded that a less invasive and a more continuous monitoring device is required to fulfill the clinical needs of intrapartum fetal monitoring. Potential specifications for such a system are also presented in this paper.
