“…At present, there are many various techniques for analyzing heavy metal toxicity such as atomic absorption spectrometry (AAS), electrothermal atomic absorption spectrometry (ET-AAS), flame atomic absorption spectrometry, hydride generation atomic absorption spectrometry, cold vapor atomic absorption spectrometry (HG-AAS, CV-AAS), inductively coupled plasma-optical emission spectrometry (ICP OES), inductively coupled plasma-mass spectrometry (ICP-MS), and HPLC-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). 15 Although these techniques are susceptible and accurate, they require highly skilled technicians, complex instruments, and a long period for implementing the examination. Nowadays, new devices capable of performing quantitative and semi-quantitative analytic information tests by implementing a biological recognition element are used.…”

Heavy metals cause considerable environmental pollution due to their extent and non-degradability in the environment. Analysis and trace levels of arsenic, lead, mercury, and cadmium as the most toxic heavy metals show that they can cause various hazards in humans’ health. To achieve rapid, high-sensitivity methods for analyzing ultra-trace amounts of heavy metals in different environmental and biological samples, novel biosensors have been designed with the participation of strategies applied in nanotechnology. This review attempted to investigate the novel, sensitive, efficient, cost-benefit, point of care, and user-friendly biosensors designed to detect these heavy metals based on functional mechanisms. The study’s search strategies included examining the primary databases from 2015 onwards and various keywords focusing on heavy metal biosensors’ performance and toxicity mechanisms. The use of aptamers and whole cells as two important bio-functional nanomaterials is remarkable in heavy metal diagnostic biosensors’ bioreceptor design. The application of hybridized nanomaterials containing a specific physicochemical function in the presence of a suitable transducer can improve the sensing performance to achieve an integrated detection system. Our study showed that in addition to both labeled and label-free detection strategies, a wide range of nanoparticles and nanocomposites were used to modify the biosensor surface platform in the detection of heavy metals. The detection limit and linear dynamic range as an essential characteristic of superior biosensors for the primary toxic metals are studied. Furthermore, the perspectives and challenges facing the design of heavy metal biosensors are outlined. The development of novel biosensors and the application of nanotechnology, especially in real samples, face challenges such as the capability to simultaneously detect multiple heavy metals, the interference process in complex matrices, the efficiency and stability of nanomaterials implemented in various laboratory conditions.

“…Nickel (II) in urine and serum samples determined with UV-VIS spectrophotometry and flame atomic absorption spectrometry techniques [20]. Recently, the various techniques such as, the inductively coupled plasma(ICP), the inductively coupled plasma mass spectrometry(ICP-MS) [21], the flame atomic absorption spectrometry F-AAS [22], the X-ray fluorescence spectrometry [23] and the electrothermal atomic absorption spectrometry (ET-AAS) were used to determine Ni and Pb ions in different matrixes [24]. Due to ultra-trace concentration of Pb and Ni in human samples (urine and serum) and difficulty matrices in human biological samples, the sample treatment was used.…”

In this study, a novel synthesis adsorbent, 1-(3-aminopropyl)-3-methylimidazolium hexafluorophosphate functionlized on multiwall carbon nanotubes ([Apmim][PF6]-MWCNTs, IL@MWCNTS) was used for nickel/lead (Ni/Pb) extraction and determination by dispersive ionic liquid micro solid-phase extraction (DIL-μ-SPE) coupled to electrothermal atomic absorption spectrometry (ET-AAS). After dilution of 20 mg of IL@MWCNTS in 200 μL of acetone, the mixture was injected to 10 mL of human serum/urine samples at pH of 8.0. After sonication for 5 min, the Ni(II) / Pb(II) were extracted by ionic liquid phase and then centrifuged for 2.5 min. The upper liquid phase set aside and Ni(II) / Pb(II) loaded in adsorbent were back-extracted by acidic solution at pH=2-3. Finally, the concentration of total nickel and lead was determined by ET-AAS. By optimizing, the limit of detection, linear range, and enrichment factor for nickel and lead were obtained (0.05 μg L−1; 0.1 μg L−1), (0.2-5.8 μg L−1; 0.4-30 μg L−1) and 24.7; 5.1, respectively (RSD less than 5%). Also, the capacity absorption of IL@MWCNTS for nickel and lead ions were achieved 149.3 mg g-1 and 162.5 mg g-1, respectively. The DIL-μ-SPE procedure was validated for nickel and lead extraction by spiking of real samples and ICP-MS analyzer.

“…Recently, various analytical techniques can be used for cadmium extraction in different water, foods and environmental samples. The various methods such as flame atomic absorption spectrometry (AAS) [12], the optical microscopy based on laser-induced photoluminescence (UV-VIS-NIR) [13], the SrFe 12 O 19 @CTAB magnetic nanoparticles with electrothermal atomic absorption spectrometry (ET-AAS) [14][15][16][17], the colorimetric sensor [18], the electrothermal vaporization coupled with optical emission spectrometry with inductively coupled plasma (ETV-ICP-OES) [19] and laserinduced breakdown spectroscopy (LIBS) [20] were used for cadmium determination in various environmental samples. Due to the low concentration of cadmium in water samples and difficulty matrixes in wastewater samples, the pretreatment is required before the determination of cadmium by instrumental analysis.…”

A simple and fast separation of cadmium (Cd) based on functionalized carbon nanotubes with 2,3-dimercapto-1-propanol (CNTs@DHSP) was achieved in water samples before a determination by atom trap flame atomic absorption spectrometry (AT-FAAS). In this study, Cd(II) ions were extracted by syringe filter membrane-micro solid phase extraction procedure(SFM-μ-SPE). Firstly, 20 mg of the CNTs@DHSP as solid-phase added to 20 mL of water sample in a syringe, then dispersed for 3 min after adjusting pH up to 7 and pass through SFM very slowly. After extraction, the Cd(II) ions were back-extracted from SFM/CNTs@DHSP by 1.0 mL of eluent in acidic pH. Finally, the cadmium concentration was measured by AT-FAAS. Under the optimal conditions, the linear range (2–90 µg L−1), LOD (0.75 µg L−1) and enrichment factor (19.6) were obtained (RSD<1.5%). The adsorption capacity of Cd(II) with the CNTs@DHSP was obtained about 152.6 mg g-1. The method was validated by certified reference materials (SRM, NIST) and ET-AAS in water samples.
