“…Much earlier, most fabricated sensors were mainly for the collecting water quality data of physical nature such as temperature ( Culler et al., 2004 ). But recent advances in optical fibre and nanomaterial-enabled screen-printed electrochemical sensors have enabled the collection of chemical or biological data such as trace metals ( Liu et al., 2019 ; Mimendia et al., 2010 ; Pesavento et al., 2019 ) pesticides ( Saleh et al., 2020 ), and microbial and organic matter ( Bridgeman et al., 2015 ). Additionally, a water quality automatic monitoring system based on general packet radio service (GPRS) data communications can continuously acquire real-time data and send them to control centres or personal gadgets ( Ionel et al., 2015 ).…”

The appropriate acquisition and processing of water quality data are crucial for water resource management. As such, published articles on water quality monitoring and assessment are meant to convey essential and reliable information to water quality experts, decision-makers, researchers, students, and the public. The implication is that such information must emanate from data obtained and analysed in an up-to-date, scientifically sound manner. Thus, inappropriate data analysis and reporting techniques could yield misleading results and mar the endeavours of achieving error-free conclusions. This study utilises the findings on water quality assessment in Nigeria over the last 20 years to reveal the likely trends in water quality research regarding data collection, data analysis, and reporting for physicochemical, bacteriological parameters, and trace organics. A total of 123 Web of Science and quartile ranked (Q1-Q4) published articles involving water quality assessment in Nigeria were analysed. Results indicated shortcomings in various aspects of data analysis and reporting. Consequently, we use simulated heatmaps and graphs to illustrate preferred ways of analysing, reporting, and visualising some regularly used descriptive and inferential statistics of water quality variables. Finally, we highlight alternative approaches to the customarily applied water quality assessment methods in Nigeria and emphasise other areas of deficiency that need attention for improved water quality research.

“…The sensitivity, as well as selectivity of various nanosensors for definite pesticides, has been reported in various studies (Table 1 ), for instance, the two different optical sensors grounded on silver nanodendrites and upconverting nanoparticles were found to detect the pesticides dimethoate and metribuzin at the levels of 0.002 ppm and 6.8 × 10 −8 M, respectively [ 107 , 108 ]. Similarly, the electrochemical nanosensor grounded using CuO nanoparticles decorated with 3D graphene nanocomposite detected malathion at the level of 0.01 nM [ 109 ] whereas the electrochemical aptasensor fabricated through chitosan-iron oxide nanocomposite detected malathion at a surprising sensitivity of 0.001 ng/mL [ 110 ].…”

Previous decades have witnessed a lot of challenges that have provoked a dire need of ensuring global food security. The process of augmenting food production has made the agricultural ecosystems to face a lot of challenges like the persistence of residual particles of different pesticides, accretion of heavy metals, and contamination with toxic elemental particles which have negatively influenced the agricultural environment. The entry of such toxic elements into the human body via agricultural products engenders numerous health effects such as nerve and bone marrow disorders, metabolic disorders, infertility, disruption of biological functions at the cellular level, and respiratory and immunological diseases. The exigency for monitoring the agroecosystems can be appreciated by contemplating the reported 220,000 annual deaths due to toxic effects of residual pesticidal particles. The present practices employed for monitoring agroecosystems rely on techniques like gas chromatography, high-performance liquid chromatography, mass spectroscopy, etc. which have multiple constraints, being expensive, tedious with cumbersome protocol, demanding sophisticated appliances along with skilled personnel. The past couple of decades have witnessed a great expansion of the science of nanotechnology and this development has largely facilitated the development of modest, quick, and economically viable bio and nanosensors for detecting different entities contaminating the natural agroecosystems with an advantage of being innocuous to human health. The growth of nanotechnology has offered rapid development of bio and nanosensors for the detection of several composites which range from several metal ions, proteins, pesticides, to the detection of complete microorganisms. Therefore, the present review focuses on different bio and nanosensors employed for monitoring agricultural ecosystems and also trying to highlight the factor affecting their implementation from proof-of-concept to the commercialization stage.

“…[1b,4] These applications require that UCNPs must be either dispersed in an adequate solvent or deposited as thin films, a fundamental trait for successful device design and preparation. [5] UCNPs based films have been already used as sensors to detect CO 2 , [5a] ammonia, [5b] pH changes, [5c-e] or pesticides. [5f] In addition, they are constitutive parts of solar cells, [5g,h] devices for photo-controlled release, [5i] electrochromic devices, [5j] and temperature sensing platforms.…”

“…Independent of their final use, the UCNPs deposition needs to be properly controlled and it is usual to use additives to either fix the UCNPs to the substrate. For example, there are reports of transparent films obtained by the incorporation of NaYF 4 based UCNPs in polymeric matrixes using poly‐(methyl methacrylate) (PMMA), [5j–l] fluorocarbon resins, [5m] cellulose, [5n] polystyrene (PS), [5a,b] PVC, [5c,f] monolithic upconverting materials based on PMMA [5o,p] and PS [5q] . Upconverting thin films based on NaYF 4 structures were also obtained by an electrodeposition method based on the decomposition of EDTA‐lanthanide precursors to drive the heterogenous NaYF 4 precipitation onto a substrate assisted by ascorbic acid [5o] or by sol‐gel methodology [5r] .…”

Emissive Platforms Employing NaYF₄‐based Upconverting Nanoparticles and Mesoporous Metal Oxide Thin Films

We present the design and synthesis of a novel optically transparent platform based on the combination of NaYF 4 : Er 3 + , Yb 3 + upconverting nanoparticles (UCNPs) and mesoporous metal oxide thin films (MOTFs). The UCNP were obtained by the thermolysis method and were deposited onto a glass substrate by spin coating. The MOTFs (TiO 2 , ZrO 2 and SiO 2 ), prepared by the combination of the sol-gel approach and the self-assembly of surfactants, were subsequently deposited on top of the particles giving rise to an ultrathin composite. The characterization of the obtained composite films indicates that they blend the properties of both starting materials: they exhibit upconverting properties, as they are capable of emitting visible light when irradiated in the NIR region, and the MOTFs deposited on top provide an ordered array of mesopores with highly accessible porosity. As the UCNPs emission properties depend on their surrounding temperature, the composite films were tested for temperature sensing applications, using both emission intensity and lifetimes of different signals, with promising results.
