“…Although several enzymes have been used to fabricate the inhibition-based biosensors to detect HMI, the most popular is urease [95][96][97][98][99]. Rodríguez et al [95,96] have developed amperometric urease-glutamic dehydrogenase based sensors for detection of copper and mercury.…”

Heavy metals such as lead, mercury, cadmium, zinc and copper are among the most important pollutants because of their non-biodegradability and toxicity above certain thresholds. Here, we review methods for sensing heavy metal ions (HMI) in water samples using screenprinted electrodes (SPEs) as transducers. The review (with 107 refs.) starts with an introduction into the topic, and this is followed by sections on (a) mercury-coated SPEs, (b) bismuth-coated SPEs, (c) gold-coated SPEs (d) chemically modified and non-modified carbon SPEs, (e) enzyme inhibition-based SPEs, and (f) an overview of commercially available electrochemical portable heavy metal analyzers. The review reveals the significance of SPEs in terms of decentralized and of in situ analysis of heavy metal ions in environmental monitoring.

“…The biosensor detected Pb (II) level more than 2.4 X 10 -1 mM. Ogonczyk et al (2005) developed a screen printed disposable urease based biosensor for the detection of heavy metals and reported a detection limit of 1 mM of lead in 20 min response time. Haron and Ray (2006) reported an optical biosensor with very low detection limit of 4.83 nM, but had application in drinking water samples only.…”

“…Furthermore, concerning solid state ion selective electrode coupled with potentiometric detection, screen-printed electrode represents a high interest when considering the technological aspects that offer low cost and simplicity of manufacturing, mass production, and long term stability [30,31]. High sensitivity, low detection limit, and no requirement of large volume of sample also other important advantages using screen-printed electrode [32].…”

A screen-printed copper ion sensor with photocurable poly(n-butyl acrylate) (pBA) membrane based on ionophore o-xylylene bis(N,N-diisobutyldithiocarbamate) (o-xc) was successfully fabricated. Poly(2-hydroxylethyl methacrylate) (pHEMA)-modified Ag/AgCl screen-printed electrode was used in the development of the sensor and the sensor was characterized by potentiometric method. Optimization of pBA membrane for the electrode was carried out by varying the compositions of sodium tetrakis [3,5-bis(trifluoromethyl)phenyl]borate (NaTFPB) and o-xc to determine the best analytical performance. The addition of NaTFPB and the increment of its ratio relative to o-xc showed super-Nernstian, small linear range, and high detection limit. For sensor fabricated based on o-xc without the addition of NaTFPB, the sensor showed Nernstian response. The best optimized sensor showed Nernstian slope with 31.29 mV/decade over a wide linear range of 1.0 × 10 -2 -1.0 × 10 -6 M and low detection limit of 1.89 × 10 -7 M. The sensitivity of this sensor was also improved over the other copper ion sensors fabricated by similar photocuring technique. In addition, based on the separate solution method (SSM), this sensor exhibited good selectivity towards copper ion with low logarithm selectivity coefficient value for monovalent and divalent cations namely K Keywords: screen-printed copper ion sensor, photocurable poly(n-butyl acrylate) membrane, ionophore o-xylylene bis(N,Ndiisobutyldithiocarbamate), potentiometry Abstrak Sensor ion kuprum bercetak skrin yang berasaskan kepada ionofor o-xililen bis(N,N-diisobutilditiokarbamat) (o-xc) dalam membran terawatfoto poli(butil-akrilat) (pBA) telah dibangunkan. Sensor ion elektrod bercetak skrin Ag/AgCl terubahsuai poli(2-hidroksiletil metakrilat) (pHEMA) telah digunakan dalam pembangunan sensor dan pencirian sensor telah dijalankan melalui kaedah potensiometri. Pengoptimunan komposisi membran sensor ion pada elektrod telah dijalankan untuk menentukan prestasi analisis yang terbaik dengan mengubah komposisi sodium tetrakis[3,5-bis(trifluorometil)fenil]borat (NaTFPB) dan o-xc. Penambahan NaTFPB dan peningkatan nisbahnya terhadap o-xc dalam membran menunjukkan super-Nernstian, julat linear yang pendek dan had pengesanan yang tinggi. Sensor ion yang direka bentuk dengan menggunakan o-xc tanpa penambahan NaTFPB menunjukkan rangsangan Nernstian. Sensor ion yang terbaik menunjukkan kecerunan Nernstian iaitu 31.29mV/dekad, julat linear dari 1.0 × 10 -2 -1.0 × 10 -6 M dan had pengesanan terendah 1.89 × 10 -7 M. Kepekaan sensor yang telah dibangunkan juga adalah lebih baik berbanding dengan sensor-sensor ion kuprum lain yang telah direka bentuk melalui kaedah rawatan foto yang sama. Nilai pekali keselektifan potensiometri ditentukan dengan kaedah larutan berasingan (SSM). Sensor tersebut juga memberikan keselektifan yang baik terhadap kation pengganggu dengan menunjukkan nilai pekali logaritma keselektifan yang rendah bagi kation monovalen dan divalen seperti K
