Abstract
A sensitive analytical method is investigated to concentrate and determine trace level of Sildenafil Citrate (SLC) present in water and urine samples. The method is based on a sample treatment using dispersive solid-phase micro-extraction (DSPME) with laboratory-made Mn@ CuS/ZnS nanocomposite loaded on activated carbon (Mn@ CuS/ZnS-NCs-AC) as a sorbent for the target analyte. The efficiency was enhanced by ultrasound-assisted (UA) with dispersive nanocomposite solid-phase micro-extraction (UA-DNSPME). Four significant variables affecting SLC recovery like; pH, eluent volume, sonication time and adsorbent mass were selected by the Plackett-Burman design (PBD) experiments. These selected factors were optimized by the central composite design (CCD) to maximize extraction of SLC. The results exhibited that the optimum conditions for maximizing extraction of SLC were 6.0 pH, 300μL eluent (acetonitrile) volume, 10mg of adsorbent and 6min sonication time. Under optimized conditions, virtuous linearity of SLC was ranged from 30 to 4000ngmL-1 with R2 of 0.99. The limit of detection (LOD) was 2.50ngmL-1 and the recoveries at two spiked levels were ranged from 97.37 to 103.21% with the relative standard deviation (RSD) less than 4.50% (n=15). The enhancement factor (EF) was 81.91. The results show that the combination UAE with DNSPME is a suitable method for the determination of SLC in water and urine samples.

Abstract
INTRODUCTION Molecularly imprinted polymers (MIPs) are synthetic receptors, characterized by a high selectivity for the selected template. Among the different applications of MIPs, their use as controlled/sustained drug delivery devices has been extensively explored, even though the optimization of such devices needs to be performed before they are applied in clinical practice. AREAS COVERED Within drug delivery, one of the most promising fields is the possibility to modulate the drug release profile in response to a specific external stimulus; MIPs represent potentially suitable vehicles, because of the possibility to insert a stimuli-responsive co-monomer in their structure. This review discusses recent advances in the use of external stimuli to modulate drug release, as well as the synthetic strategies devoted to increase the water compatibility of these systems, which is a base requirement for their application in biomedicine. EXPERT OPINION Although it is easy to imagine imprinted polymers for biomedical applications, several aspects have to be further investigated, such as the in vivo studies, efficiency and biocompatibility. However, we think that in the next few years it will possible to see unprecedented progress in the preparation of such systems and the translational application of these intelligent structures in medicine.

Abstract
A molecularly imprinted polymer (MIP) for
tri-O-acetyladenosine (TOAA), PPM(TOAA), was
prepared by the combined use of methacrylic acid (MAA) and
Zn(II)tetra(4′-methacryloxyphenoxy) phthalocyanine as functional
monomers. This MIP exhibited a higher binding ability for TOAA
compared to the MIP prepared using only MAA, PM(TOAA), in batch
rebinding tests. Scatchard analysis gave a higher association
constant of PPM(TOAA) for TOAA (2.96×104 M−1) than that of
PM(TOAA) (1.48×104 M−1). The MIP
prepared using only the zinc-phthalocyanine, PP(TOAA), did
not show any binding capacity for TOAA. This means that the
phthalocyanine in the MIP contributes to higher affinities,
although it barely interacts with TOAA. Since selectivity
for this kind of MIPs is more important than binding
affinity, the binding of TOAA and a structurally related
compound,
tri-O-acetyluridine (TOAU), on the polymers was
investigated. Both PPM(TOAA) and PM(TOAA) exhibited binding
affinities for TOAA while they did not show any binding capacity
for TOAU.

Abstract
Molecularly imprinted polymers (MIPs) are tailor-made synthetic materials possessing specific cavities designed for a target molecule. Since they recognise their target analyte with affinities and selectivities comparable to those of antibody-antigen, enzyme-substrate and ligand-receptor interactions, they are often referred to as synthetic receptors or plastic antibodies. In this review, we describe the great potential and recent developments of MIPs in affinity separations, with emphasis on their application to the solid-phase extraction (SPE) of analytes from complex matrices. Research efforts made in this field to obtain water-compatible polymers for their applicability in aqueous environments are described. We particularly discuss problems encountered in the use of MIPs in SPE and the attempts carried out to improve their efficiency.

Abstract
Solid phase extraction is routinely used in many different areas of analytical chemistry. Some of the main fields are environmental, biological, and food chemistry, where cleaning and pre-concentration of the sample are important steps in the analytical protocol. Molecularly imprinted polymers (MIPs) have attracted attention because they show promise as compound-selective or group-selective media. The application of these synthetic polymers as sorbents allows not only pre-concentration and cleaning of the sample but also selective extraction of the target analyte, which is important, particularly when the sample is complex and impurities can interfere with quantification. This review surveys the selectivity of MIPs in solid phase extraction of various kinds of analytes.

Abstract
A novel highly selective sample cleanup procedure combining molecular imprinting and matrix solid-phase dispersion (MI-MSPD) was developed for the simultaneous isolation of ofloxacin, pefloxacin, norflorxacin, ciprofloxacin, and enrofloxacin in chicken eggs and swine tissues followed by high-performance liquid chromatography with fluorescence detection. The novel ofloxacin imprinted polymers synthesized in water-containing systems show high selectivity for the five fluoroquinolones in aqueous environment and the affinity can be easily adjusted by the pH of solution. Compared with conventional MSPD methods, using MIPs as selective MSPD sorbents, the five fluoroquinolones could be selectively extracted from a biological matrix and all matrix interferences were eliminated simultaneously. The average recoveries of the five fluoroquinolones were ranged from 85.7 to 104.6% for eggs and 86.8 to 102.7% for tissues with relative standard deviations of less than 7.0%. Detection limits for the identification of the five fluoroquinolones in eggs and tissues ranged from 0.05 to 0.09 ng/g.
