Summary: A multi-responsive receptor consisting of two (acridinium-Zn(II) porphyrin) conjugates has been designed, showing eight states resulting from the cascade of recognition and responsive events. The binding constant between the receptor and a ditopic guest can be modulated by the addition of nucleophiles and oxidation of the porphyrin units. The acridinium/acridane conversion leads to a significant change in the photophysical properties, with a switch from electron to energy transfer processes. Interestingly, charge-transfer luminescence in the near-infrared has been observed for the bis(acridinium-Zn(II) porphyrin) receptor.

Summary: Liquid crystalline polymers are used to create miniature soft robots that can be controlled using light. This study focuses on the manipulation of photoresponsive polymers at the micrometer scale, specifically their rotation and speed control. By using a circularly polarized trapping laser, the polymer particles exhibit uni- and bidirectional rotation, with the rotation rate determined by the optical torque. The angular speed can be controlled by small structural changes induced by UV light absorption. This research provides evidence of motion and speed control in light-responsive polymer particles and opens up possibilities for light-controlled rotary microengines at the micrometer scale.

Summary: By using the Cartesian multipole expansion theory, a general relationship between lateral optical force (LOF) and spin and momentum is established, demonstrating that the LOF exerted on an isotropic achiral particle is proportional to the optical transverse spin in the incident evanescent wave. This anomalous LOF suggests the direct detectability of the transverse spin of light and mimics the transverse shift of light in the spin Hall effect of photons, manifesting itself as a mechanical consequence of the Berry phase effect.

Summary: A new methodology to enhance the sensitivity of a long period fiber grating sensor (LPFG) at the Turn Around Point (TAP) has been presented. The LPFG sensor was fabricated by etching the fiber up to 20.4 μm, until the sidelobes of dispersed LP0,2 cladding mode appeared near TAP in aqueous medium. The dual peak sensitivity of the sidelobes was found to be 16,044 nm/SRIU (surrounding refractive index units) in the RI range from 1.333 to 1.3335.

Summary: This study presents a methodology to enhance the sensitivity of long-period fiber gratings (LPFGs) by combining three different enhancement approaches, including working near mode transition (MT) of a cladding mode (CM), working near the turn-around point of a CM, and enhancing the evanescent field of CMs by reducing the cladding diameter or increasing the order number of CMs. An electrostatic self-assembly (ESA) process was used to deposit a polymeric overlay with a chosen thickness onto the etched fiber to combine these enhancement methodologies. The effectiveness of the applied methodology for sensitivity enhancement was demonstrated by performing an IgG/anti-IgG immunoassay in human serum in a thermostated microfluidic system, with limits of detection (LODs) calculated to be 6.9 x 10^(-8) & mu;g/mL and 4.5 x 10^(-6) & mu;g/mL using different procedures.

Summary: Alzheimer's disease (AD) is a neurodegenerative disease with high mortality rate among the elderly. Current diagnostic systems lack sensitivity, reproducibility, accuracy, and specificity. This study presents a lab-on-fiber (LoF) technology using a D-shaped single-mode fiber combined with nanometer-scale metal-oxide film for AD biomarker detection. The proposed sensing system increases the interaction between the fiber and surrounding medium, achieving highly sensitive detection of Tau protein, a classical AD biomarker. The LoF biosensor offers a promising solution for early screening and personalized medicine in AD.

Summary: Gold-coated tilted fiber Bragg gratings (TFBGs) have been extensively studied for biosensing purposes. A more sensitive demodulation technique based on gold-coated TFBG spectra has been introduced, and successfully applied for the detection of HER2 proteins.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
