“…The limit of detection, reproducibility (% relative standard deviation), required sample size, analysis time, basic instrument cost, necessary skill for instrument operation, and type of data generated are tabulated for each method. (Wahed et al 2006;Behari & Prakash 2006;Rahman et al 2002;Deng et al 2013;Jakariya et al 2007; United States Environmental Protection Agency Office of Water 1999; Skoog et al 2006) (Klaue & Blum 1999;Francesconi & Kuehnelt 2004;Roje et al 2007;Gómez-Ariza et al 2000;Lindberg et al 2007 1 lists some general performance attributes such as limit of detection, reproducibility, required sample volume and time per analysis, as well as the costs and expertise needed to run each of these three methods. Although they are powerful analytical tools, the high cost and maintenance associated with laboratory methods renders them unsuitable for routine arsenic monitoring in developing regions (Figure 3).…”

Ultrasound imaging based on transmitting plane waves (PW) enables ultrafast imaging. Coherent PW compounding ultrasound imaging can reach the image quality of optimal multifocus image. In the image reconstruction, it was assumed that an infinite extent PWs was emitted. In this thesis, we propose a new image reconstruction algorithm – Synthetic-aperture plane-wave (SAPW) imaging – without using this assumption. The SAPW imaging was compared with the PWs imaging in numerical simulations and experimental measurements. The measured RF data in PW imaging was first decoded in the frequency domain using a pseudoinverse algorithm to estimate the RF data Then, SAPW RF data were used to reconstruct images through the standard synthetic transit aperture (STA) method. Main improvements in the image quality of the SAPW imaging in comparison with the PWs imaging are increases in the depth of penetration and the field of view when contrast-to-noise ratio (CNR) was used as a quantitative metric

Porphyrins have planar and conjugated structures, good optical properties, and other special functional properties. Owing to these excellent properties, in recent years, porphyrins and their analogues have emerged as a multifunctional platform for chemical sensors. The rich chemistry of these molecules offers many possibilities for metal ions detection. This review mainly discusses two types of molecular porphyrin and porphyrin composite sensors for metal ions detection, because porphyrins can be functionalized to improve their functional properties, which can introduce more chemical and functional sites. According to the different application materials, the section of porphyrin composite sensors is divided into five sub-categories: (1) porphyrin film, (2) porphyrin metal complex, (3) metal–organic frameworks, (4) graphene materials, and (5) other materials, respectively.

“… 5 − 7 Various approaches including atomic absorption spectroscopy, inductively coupled plasma mass spectrometry, atomic fluorescence spectroscopy, and high-performance liquid chromatography have been utilized for the detection of As(III) with stable analysis, good reproducibility, and excellent sensitivity. 8 − 11 However, these complicated and costly high-end instruments require well-trained technicians for their maintenance and operation. Moreover, the detection of As(III) with these instruments usually involves complex, tedious, and time-consuming sample preparation in a central laboratory.…”

High-throughput and rapid arsenite (As(III)) monitoring is an urgent task to deal with the critical threat from As(III) contamination in the environment. In this study, an effective, portable, and sensitive As(III) assay was developed using the plasmonic silver (pAg) chips for As(III) detection. The pAg chips were fabricated by a simple seed-mediated method to grow the silver nanoisland films (Ag-NIFs) with the compact nanoislands and adjustable interisland gaps on the large-sized substrates. With appropriate surface functionalization and optimal chip manufacturing, Cy7.5 fluorescence dye can be immobilized on the surface of Ag-NIFs in the presence of As(III) to output the enhanced fluorescence signals up to 10-fold and improve the detection limit of As(III) less than 10 ppb. According to our results, the high-throughput detection measurements and wide dynamic range over 4 orders of magnitude implied the broad prospects of pAg chips in fluorescence-enhanced assays. The proposed As(III) assay has shown great opportunities for the practical application of ultratrace As(III) monitoring.
