The water-soluble conjugated polyelectrolyte, poly[3-(1′-propyloxy-3′-sodium sulfonate) thiophene] (PTH-n3-SO3Na), was prepared. The interaction between the PTH-n3-SO3Na and bovine serum albumin (BSA) was investigated using UV-vis spectroscopy. It was found that the PTH-n3-SO3Na could be used as biosensor to detect BSA.

AbstractHighly ordered gold NC/silica films are synthesized by self-assembly of water-soluble gold nanocrystal micelles and soluble silica using a sol-gel spin-coating technique. The optical properties are analyzed using ellipsometry and ultraviolet-visible spectroscopy. The absorption spectra show a strong surface plasmon absorption band at ∼520 nm for all samples. Angular excitation spectra of the surface plasmon show a steep dip in the reflectivity curve at ∼65°. Charge transport behavior of the films is examined using metal-oxide-semiconductor (MOS) structures.MOS capacitor samples exhibit charge storage with discharge behavior dominated by electron transport within the gold NC arrays.

[Formula: see text]-methyl mesoporphyrin IX (NMM) is a water-soluble, non-symmetric porphyrin with excellent optical properties and unparalleled selectivity for G-quadruplex (GQ) DNA. G-quadruplexes are non-canonical DNA structures formed by guanine-rich sequences. They are implicated in genomic stability, longevity, and cancer. The ability of NMM to selectively recognize GQ structures makes it a valuable scaffold for designing novel GQ binders. In this review, we survey the literature describing the GQ-binding properties of NMM as well as its wide utility in chemistry and biology. We start with the discovery of the GQ-binding properties of NMM and the development of NMM-binding aptamers. We then discuss the optical properties of NMM, focusing on the light-switch effect — high fluorescence of NMM induced upon its binding to GQ DNA. Additionally, we examine the affinity and selectivity of NMM for GQs, as well as its ability to stabilize GQ structures and favor parallel GQ conformations. Furthermore, a portion of the review is dedicated to the applications of NMM-GQ complexes as biosensors for heavy metals, small molecules ([Formula: see text] ATP and pesticides), DNA, and proteins. Finally and importantly, we discuss the utility of NMM as a probe to investigate the roles of GQs in biological processes.
