“…The applicability of the proposed device was demonstrated by the determination of ammonium ions in wastewaters and fertilizers, showing statistically comparable results with those obtained by a reference gas-diffusion flow injection method. Ammonia was also determined in fish pond water samples using a µPAD with the acceptor layer modified with anthocyanins (extracted from a red rose) that shows remarkable stability (at least 1 month) [ 100 ]. The proposed approach was also applied to the indirect colorimetric determination of mercury in highly contaminated soils (LOD: 20 mg/L) [ 101 ] and the fluorimetric determination of iodate in iodized salts and fish sauces using albumin-stabilized gold nanoclusters as a recognition element [ 102 ].…”

The growing interest in the development of cost-effective, straightforward, and rapid analytical systems has found cellulose-based materials, including cellulose derivatives, cellulose-based gels, nanocellulosic materials, and the corresponding (nano)cellulose-based composites, to be valuable platforms for sensor development. The present work presents recent advances in the development of cellulose-based sensors for the determination of volatile analytes and derivatives of analytical relevance. In particular, strategies described in the literature for the fabrication and modification of cellulose-based substrates with responsive materials are summarized. In addition, selected contributions reported in the field of paper-based volatile sensors are discussed, with a particular emphasis on quick response (QR) code paper-based platforms, intelligent films for food freshness monitoring, and sensor arrays for volatile discrimination purposes. Furthermore, analytical strategies devised for the determination of ionic species by in situ generation of volatile derivatives in both paper-based analytical devices (PADs) and microfluidic PADs will also be described.

“…Since the first report by the Whitesides group from Harvard University [16], there has been a vast development of μ-PADs as analytical tools for applications in food safety [17], health care [18][19] and environmental science [20][21], with some μ-PADs particularly devoted to the detection of Mn(II) in water samples [22][23][24]. Meredith et al [22] reported the development of paper-based microfluidics for the selective determination of Mn(II) in the presence of other cations using 4-(2-pyridylazo)resorcinol (PAR) as the non-specific colorimetric ligand.…”

The development of a simple yet greener microfluidic paper-based analytical device (μ-PAD) for on-site detection of Mn(II) in various types of waters using tannin as a natural reagent was described. The μ-PAD consists of twelve detection zones, created on a Whatman Number 1 filter paper by a simple drawing technique using an acrylic watercolor. The detection of Mn(II) was based on the color change on the reaction zone due to the reaction between Mn(II) and the pre-deposited tannin. The μ-PAD image was captured by a portable smartphone detector, and the blue intensity was digitized using a color picker application to generate the reflectance as the analytical response. The proposed method was characterized by a linear dynamic range of 0.05–0.25 mg L−1 with the limit of detection (LOD) for the determination of Mn(II) of 0.026 mg L−1. The other analytical merits of the proposed method, such as precision (RSD, 1.107%), accuracy (E, 6.697%), and recovery (104–112%), were all comparable to the existing spectrophotometric methods. The method’s successful application to natural water samples from manganese mining sites aligns with the reference spectrophotometric method, indicating its good selectivity and accuracy without significant influence of commonly associated interfering ions.
