Summary: Molecularly imprinted polymers (MIPs) have emerged as artificial antibodies with significant applications in the field of bioanalysis. Conventional bulk MIPs suffer from limitations such as low adsorption capacity, poor site accessibility, restricted mass transfer, and irregular morphology. Surface molecularly imprinted polymers (SMIPs) have garnered attention due to their large surface area, fast mass transfer, and high adsorption capacity and efficiency. This review provides a comprehensive summary of the preparation of SMIPs, including components and polymerization strategies, and discusses their applications in amino acids, peptides, and proteins. Furthermore, future trends and challenges in the design and development of SMIPs are described.

Summary: This article describes the synthesis and photoluminescent properties of novel α-amino acids, in which the chromophores containing biaryl benzotriazinone exhibit dual emission fluorescence through locally excited (LE) and twisted intramolecular charge transfer (TICT) states. The intensity of each emission band can be controlled by the electronics and position of the substituents, and this led to the design of a 2-methoxyphenyl analogue that, due to twisting, displays bright TICT fluorescence, solvatochromism, and pH sensitivity.

Summary: It is observed that nanoparticles bind closely to specific types of extracellular matrix components, namely retraction fibers and migrasomes, which are located at the rear of tumor cells during their migration. This interaction alters cell morphology, limits cell motion range, and changes cell adhesion. Nanoparticles inhibit tumor cell removal and anti-metastasis potential is confirmed in vitro. Mechanically, nanoparticles form a rigid shell on the surface of migrasomes and retraction fibers, blocking their recognition, endocytosis, and elimination by surrounding tumor cells. This interference reduces the promotion effect of migrasomes on cell movement.

Summary: Numerous studies have emphasized the importance of hydroxyl groups on the substrate for achieving good adhesion properties of epoxy adhesives. However, the optimal surface density of these functional groups for cohesive failure patterns has not been clearly defined. In this study, self-assembled monolayers (SAMs) with controlled hydroxyl group density and minimal roughness were fabricated using bromine-terminated monolayers. The conversion of bromides to hydroxyl groups was achieved using mercury (II) oxide-assisted solvolysis and thorough washing. Surface chemistry and monolayer structure were characterized using various techniques. These well-controlled SAMs were used as model surfaces to test the adhesion properties of a commercial epoxy adhesive. Peel tests revealed a threshold value of approximately 3 OH/nm(2) for transitioning from adhesive to cohesive failure patterns. This methodology is particularly relevant for studying the adhesion mechanism of adhesive formulations on materials with oxide coatings, where surface chemistry is the key factor that varies between substrates.

Summary: This study investigates the specific interactions between titania membrane and fluoride anions during ultrafiltration operation. Numerical investigations show that at low concentrations, the transmission of fluoride-based salts decreases due to a modification of the electric charge of the membrane surface caused by fluoride ions. This modification can be explained by the substitution of oxygen atom with a fluoride ion.

Summary: Increased life expectancy in industrialized countries has led to a higher incidence of osteoporosis, resulting in a greater demand for bioactive bone implants. The integration of these implants can be improved through chemical modifications, particularly by adding amino-group-containing coatings that enhance cell attachment and signaling. This study focused on studying the role of amino group density in promoting positive cell behavior by developing controlled amino-rich nanolayers.
