“…Our recommendation to other researchers is to attempt evaluation of their own methods using the RGB model (the freely available online Excel spreadsheet template may also be helpful for performing method assessment [ 13 ]). The data provided may allow for the development of additional guidelines for the assessment of individual criteria in the future, and thus contribute to an increase in the objectivity of assessments and comparisons using this tool.…”

“…The RGB model used here refers to the 12 general rules divided into red (R1–R4), green (G1–G4) and blue (B1–B4) corresponding to the three attributes of a method: analytical, ecological and practical, respectively [ 13 ]. Overall average score, the so-called whiteness, is a measure of the overall quality and sustainability of the method.…”

“…The RGB model has already been successfully used to evaluate and compare both procedures [ 10 ] and analytical methods [ 11 ], and its effectiveness has been demonstrated against other models of similar purpose [ 12 ]. It also became an inspiration for the recently proposed new idea “White Analytical Chemistry” (WAC) promoting the coherence and synergy of the analytical, ecological and practical attributes, striving for sustainability of analytical methods [ 13 ].…”

An original strategy to evaluate analytical procedures is proposed and applied to verify if the flow-based methods, generally favorable in terms of green chemistry, are competitive when their evaluation also relies on other criteria. To this end, eight methods for the determination of zinc in waters, including four flow-based ones, were compared and the Red–Green–Blue (RGB) model was exploited. This model takes into account several features related to the general quality of an analytical method, namely, its analytical efficiency, compliance with the green analytical chemistry, as well as practical and economic usefulness. Amongst the investigated methods, the best was the flow-based spectrofluorimetric one, and a negative example was that one involving a flow module, ICP ionization and MS detection, which was very good in analytical terms, but worse in relation to other aspects, which significantly limits its overall potential. Good assessments were also noted for non-flow electrochemical methods, which attract attention with a high degree of balance of features and, therefore, high versatility. The original attempt to confront several worldwide accepted analytical strategies, although to some extent subjective and with limitations, provides interesting information and indications, establishing a novel direction towards the development and evaluation of analytical methods.

“…Recently, Nowak et al (28) presented a new perspective for sustainable development in analytical chemistry named as WAC as an analogy to the 12 principles of green analytical chemistry. The concept of WAC was based in a tool known as Red-Green-Blue (RGB) model, being analytical efficiency represented by the color red; the environmental friendliness and safety represented by the color green; and the economic and practical aspects represented by the color blue.…”

Research background. Sorbate and benzoate are important preservatives in food products, but these compounds can also have genotoxic effects, causing health risks to their consumers. In this regard, this study aims to determine the concentrations of sorbate and benzoate in Brazilian samples of mustard, ketchup and tomato sauce using a sub-minute capillary electrophoresis method adequately validated. Experimental approach. In this study, sorbate and benzoate were evaluated in sauces samples by capillary electrophoresis using a simple sample preparation procedure. Previously, the method was validated according to Eurachem guidelines, and its greenness was assessed by Eco-scale. Results and conclusions. The fitness for purpose of the method, as well as its suitability for the analysis of the studied matrixes and its agreement with the principles of green chemistry were checked and confirmed. Also, according to our findings, among the 30 commercial samples assessed, six of them presented some mislabelling or non-compliance with European or Brazilian legislation, reinforcing the constant need for quality assessment and surveillance of food products. Novelty and scientific contribution. So far, few studies have been found related to investigating these preservatives in these types of foods, highlighting the significance and contribution of this manuscript to the improvement of knowledge in the field.

“…The 11th Principle of Green Chemistry boosts the in situ analysis [ 1 ], but this feature is not enough. Thus, Green Analytical Chemistry has recently opened the concept of White Analytical Chemistry which extends and complements the Green Analytical Chemistry vision for giving coherence and synergy of the analytical, ecological, and practical attributes [ 2 ].…”

Origami Paper-Based Electrochemical (Bio)Sensors: State of the Art and Perspective

In the last 10 years, paper-based electrochemical biosensors have gathered attention from the scientific community for their unique advantages and sustainability vision. The use of papers in the design the electrochemical biosensors confers to these analytical tools several interesting features such as the management of the solution flow without external equipment, the fabrication of reagent-free devices exploiting the porosity of the paper to store the reagents, and the unprecedented capability to detect the target analyte in gas phase without any sampling system. Furthermore, cost-effective fabrication using printing technologies, including wax and screen-printing, combined with the use of this eco-friendly substrate and the possibility of reducing waste management after measuring by the incineration of the sensor, designate these type of sensors as eco-designed analytical tools. Additionally, the foldability feature of the paper has been recently exploited to design and fabricate 3D multifarious biosensors, which are able to detect different target analytes by using enzymes, antibodies, DNA, molecularly imprinted polymers, and cells as biocomponents. Interestingly, the 3D structure has recently boosted the self-powered paper-based biosensors, opening new frontiers in origami devices. This review aims to give an overview of the current state origami paper-based biosensors, pointing out how the foldability of the paper allows for the development of sensitive, selective, and easy-to-use smart and sustainable analytical devices.
