“…Among these applications, there is a special and interesting one which is the SPE method using MIPs as the sorbent. The MIPs have been prepared and applied in selective recognition and enrichment of ␤-lactam antibiotics [30][31][32], and they exhibited high recognition selectivity.…”

“…River water samples were collected from upstream to downstream, which a drainage river that connects with a drainage ditch of the pharmaceutical factories located in this area, and receives the effluent from two WWTPs. The β-lactam antibiotics were found within the range of 0-9.56 μg/L in river water at the downstream of antibiotics manufacturers, and none were detected in the tap water [16]. Further in Southeast Asia country, researcher identified a method to determine the risk of pharmaceutical compounds applied it to 10 of the human-use pharmaceuticals detected in Taiwan's Sindian River [17].…”

Abstract. Southeast Asia countries were developing countries, with the rapid development for a better living condition leads to longer life expectancy, which increased total population. It may result in increased the demand of pharmaceutical in domestic use and or in hospital. Although most wastewater treatment plants (WWTPs) met the local authority's regulatory requirement, there are still many pharmaceutical compound incompletely removed and discharge to the water stream and enter the environment. Recently many studies and researches have published on the occurrence and source as well as the fate of pharmaceuticals all over the world including Asia. As part of Asia region, Southeast Asia countries (Malaysia, Philippines, Singapore, Thailand, Vietnam, Brunei, Cambodia, and Lao PDR) seem has lack of research knowledge and information regarding this emerging pollutant issues compared to developed Asia country as China, Korea and Hong Kong. In this paper, it will review recent studies occurrences (surface and wastewater) on most common pharmaceuticals with several recommendations to overcome and thus summarise the actual situation in Southeast Asia.

“…This leaking during on-line measurement can lead to false results. 32,33 In contrast, if an MIP is applied as a recognition unit in a chemosensor, this leaking does not interfere much because the analytical signal is generated only when the molecule binds to its imprinted cavity. Pioneering aspects of the present research include the implementation of the molecular imprinting strategy for solving problems of the trace level chiral sensing of amino acids.…”

Molecularly imprinted polymer based extended-gate field-effect transistor chemosensors for phenylalanine enantioselective sensing

aeChemosensing systems were devised for the enantioselective determination of D-and L-phenylalanine (D-and L-Phe). As recognition units of these systems, molecularly imprinted polymers (MIPs) were designed, guided by DFT calculations, and then synthesized. For the preparation of these MIPs, carboxy derivatized bis(bithiophene) was used as the functional monomer. Both templated and templateextracted MIP films as well as non-imprinted polymer (NIP) films were characterized by IR spectroscopy to prove Phe templation, and then extraction. Extended-gate field-effect transistors (EG-FETs) served as transducers. The EG-FET gates were coated with D-or (L-Phe)-templated MIP films, by electropolymerization, to result in complete chemosensors. These chemosensors rapidly and selectively responded to D-and L-Phe enantiomer analytes. They readily discriminated between a homologous series of analytes differing by a single atom as well as pairs of enantiomers differing in their three-dimensional structures. Linear dynamic concentration ranges for D-and L-Phe extended from 13 to 100 mM. For both Phe enantiomers, the limit of detection was 13 mM. The enantioselectivity factor was B2.3 for both chemosensors.
