pH-responsive allochroic nanoparticles for the multicolor detection of breast cancer biomarkers

Estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) are the three crucial biomarkers for the clinical diagnosis of breast cancer. Sensitive and precise detection of ER, PR, and HER2 is of great significance for the diagnosis of breast cancer. Herein, through a simple solvent-induced self-assembly process, the self-carried allochroic nanoparticles were prepared by using some hydrophobic pH indicator molecules for allochroic NPs-linked immunosorbent assay (named ALISA) of ER, PR, and HER2, respectively. Meanwhile, the introduction of bovine serum albumin (BSA) and antibody (Ab) enhanced the dispersity of the self-assembled nanoparticles as signal tags. Since the ultra-high loading and high-efficiency release of pH indicators, the ALISA exhibitssatisfactory selectivity and sensitivity, which demonstrated the great potential in the early diagnosis and postoperative monitoring of breast cancers. Furthermore, the smartphone was introduced to combine with the ALISA for point-of-care testing, indicating the high feasibility in practical applications.

Superomniphobic Papers for On-Paper pH Sensors

Paper-based superomniphobic surfaces are of great interest because paper is flexible, inexpensive, lightweight, breathable, and recyclable. Prior reports on paper-based superomniphobic surfaces have failed to demonstrate high mobility with low surface tension liquids. In order to overcome this issue, in this work, superomniphobic papers are developed through growth of nanofilaments on inherent microfibers of papers without noticeably altering their microscale features (i.e., diameter and distance of the microfibers). These superomniphobic papers display very low roll-off angle, indicative of ultra-high droplet mobility, even with low surface tension liquids. Here, a facile method is also developed to control the motion and adhesion of the droplets on the superomniphobic paper. Utilizing such liquid mobility in a controlled manner on these superomniphobic papers, a simple on-paper pH sensor is fabricated. It is anticipated that this on-paper, simple, and rapid detection methodology can also be extended to the colorimetric sensing of protein and chemical assays. Further, these superomniphobic papers have potential applications in water?oil separation and enhanced weight-bearing capacity.

Metal-Polydopamine Framework: An Innovative Signal-Generation Tag for Colorimetric Immunoassay

In this work, an innovative enzyme-free colorimetric immunoassay was proposed for the sensitive detection of alpha-fetoprotein (AFP) by introducing thymolphthalein-modified metal-polydopamine framework (MPDA@TP) for the signal generation and amplification. Using zeolitic imidazolate framework (ZIF-67) as the template, the hollow-structured metal-polydopamine framework (MPDA) with high surface recovery and abundant groups was synthesized and functionalized with thymolphthalein (TP) molecules via typical pi-stacking reaction. In the presence of target AFP, an MPDA@TP-linked immunosorbent assay (MLISA) was implemented on the capture antibody-modified microplate by using detection antibody-labeled MPDA@TP as the secondary antibody. Upon alkaline solution introduction, the coated hydrophobic TP on the MPDA was deprotonated into hydrophilic TP2- ion and dissolved in the solution, thereby resulting in the color change of the solution from nearly colorless to deep blue, and the increasing absorbance of the solution at 595 nm. Importantly, the MPDA@TP-based immunoassay could exhibit high sensitivity for the quantitative detection of target AFP on the basis of the absorbance within a linear range of 10-1000 pg mL-1 at a low detection limit of 2.3 pg mL-1. Furthermore, this system was validated preliminarily to screen human serum specimens with well-matched results for the referenced AFP ELISA kit. Taking advantage of simplicity, enzyme-free, convenience, and sensitivity, MPDA@TP-linked immunosorbent assay has the potential for the application in scientific research and clinical diagnosis.

Modulation of the excited state intramolecular electron transfer reaction and dual fluorescence of crystal violet lactone in room temperature ionic liquids

The influence of polarity, viscosity, and hydrogen bond donating ability of the medium on the fluorescence behavior of crystal violet lactone (CVL), which undergoes excited state electron transfer reaction and exhibits dual fluorescence from two different electronic states, termed as CTA and CTB, has been studied in six different room temperature ionic liquids (ILs) using steady state and time-resolved emission techniques. It is shown that the excited state CTA a?? CTB transformation and dual fluorescence of CVL can be controlled by appropriate choice of the ILs. While dual fluorescence of CVL is clearly observed in pyrrolidinium IL, the molecule exhibits a single fluorescence band in ammonium IL. While the second emission from the CTB state can barely be seen in 1,3-dialkylimidazolium ILs, dual fluorescence is quite prominent in 1-butyl-2,3-dimethylimidazolium IL, [bmMim][Tf2N]. These contrasting results have been explained taking into account the hydrogen bonding interactions of the 1,3-dialkylimidazolium ions (mediated through the C(2)-hydrogen) with CVL and the viscosity of the ILs. The excited state CT A a?? CTB reaction kinetics has been studied in IL by monitoring the time-evolution of the CTB emission in [bmMim][Tf 2N]. The solvation dynamics in this IL has been studied by following the dynamic fluorescence Stokes shift of C153, which is used as a probe molecule. A comparison of the excited state reaction time and solvation time suggests that the rate of the CTA a?? CTB reaction in moderately viscous ILs is primarily dictated by the rate of solvation. Very little or negligible excitation wavelength dependence of the emission behavior of CVL can be observed in these ILs. A 2010 American Chemical Society.

Voltammetric Determination of Quercetin and Rutin on Their Simultaneous Presence on an Electrode Modified with Polythymolphthalein

Abstract: A voltammetric method is developed for the determination of quercetin and rutin in the simultaneous presence on a glassy carbon electrode modified with carbon nanofibers and polythymolphthalein. The conditions of the potentiodynamic electrolysis of thymolphthalein providing the maximum difference in the oxidation potentials of quercetin and rutin equal to 136 mV are found. Thymolphthalein electropolymerization should be carried out in a 100 muM solution by the 10-fold cycling of the potential from 0 to 1.7 V at a sweep rate of 75 mV/s in phosphate buffer solution with pH 7.0. The electrode modified with polythymolphthalein is characterized by scanning electron microscopy, cyclic voltammetry, and electrochemical impedance. It is found that the oxidation of quercetin proceeds irreversibly, and that of rutin, quasi-reversibly with the participation of two electrons and two protons and is controlled by the adsorption of analytes on the electrode surface. The analytical range is 0.025?1.00 muM for both analytes, and the limits of detection are 7.3 nM for quercetin and 4.7 nM for rutin. The selectivity of the electrode response to quercetin and rutin in the presence of inorganic ions, saccharides, and ascorbic and p-coumaric acids is shown. The developed method is tested on real samples (linden Tilia L. flowers and onions).

Hydrophilic crosslinking monomers and polymers made therefrom

This invention relates primarily to organofunctional monomers, predominantly dimethacrylates and/or diacrylates containing one or more (predominantly two carboxyl groups, with moieties that provide sufficient affinity with water to allow any desired amount of water and/or miscible fugitive solvents to be mixed homogeneously with these monomers and formulations containing them. The activity of water in the monomer formulations can be adjusted so that it is equal to the water activity in biological tissues. This promotes biocompatibility and enhances the adhesive characteristics of polymers prepared from these formulations. Probability statistics are disclosed that optimize the compositions of polymer reaction products. Also disclosed are novel, dual-purpose synthesis reaction monomers, catalysts, stabilizers, polymerization initiators and/or cophotoinitiators that have solubility and surface-activity characteristics such that they will not become separated by partitioning during penetration of hydrated layers on or in the substrate adherends. These formulations may be used for light-cured or chemical-cured bonding to soft or hard tissues, metal, porcelain, ceramic or other surfaces. A potential application for the composition is the holding together, by an overlying layer of resulting polymer, tissues adjacent to incisions and wounds. The polymerized composition might replace suturing, and allow for the healing of soft tissues.

A nontoxic reversible thermochromic binary system: Via pi-pi Stacking of sulfonephthaleins

The mechanisms of thermochromic materials are mostly based on Bragg reflection, surface plasmon absorption, molecular structure changes, conformational stretching or aggregation. Here, a simple class of dye-solvent binary systems with clear and reversible thermochromism around ambient temperatures is reported with an alternative mechanism. This system comprises commercially available sulfonephthaleins dissolved in liquid linear chain esters, acids or alcohols, which demonstrate colour changes at different temperatures when the solvents transition from solid to liquid states. The colour changing mechanism is based on pi-pi stacked aggregation or disaggregation of the sulfonephthalein dyes. Cell toxicity tests confirmed that the sulfonephthalein dyes are less toxic to NIH-3T3 cells than cyanidin chloride, which is the only reported nontoxic food dye affording thermochromism, while this is based on an alternative mechanism. With the choice of a nontoxic solvent, this binary system can form a nontoxic thermochromic material.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1552-42-7 is helpful to your research. Electric Literature of 1552-42-7
