“…A ring opening polymerization (ROP) approach was chosen, compared to the polycondensation of hydroxycarboxylic acids, since ROP ensures a low polymer dispersity (i.e., 1.1 to 1.6). 26 The polymerization reaction continued until all ε-caprolactone monomers had completely reacted, as evidenced by the shift of the H e proton signal from 4.21 ppm to 4.06 ppm (Fig. S1 †).…”

“…The IR analysis revealed similarity between MI and control fibers via the obtained spectra, as shown in Figure 6 A. The characteristic peaks of the PCL matrix are evident at 1721, 2866, and 2941 cm −1 , which are assigned to C=O stretching of ester carbonyl group and symmetric and asymmetric CH 2 stretching vibrations, respectively [ 37 ]. The vibrational peak at 575 cm −1 could be assigned to Fe-O stretching vibration of the added magnetite [ 38 ].…”

The present study describes the fabrication of molecularly imprinted (MI) magnetic beaded fibers using electrospinning. Rosmarinic acid was selected as exemplary yet relevant template during molecular imprinting. A “design of experiments” methodology was used for optimizing the electrospinning process. Four factors, i.e., the concentration of the biodegradable polymer (polycaprolactone), the applied voltage, the flow rate, and the collector distance were varied in a central composite design. The production process was then optimized according to the suitability of the beaded fibers during microrobot fabrication, actuation, and drug release. The optimum average fiber diameter of MI beaded fibers was determined at 857 ± 390 nm with an average number of beads at 0.011 ± 0.002 per µm2. In vitro release profiles of the optimized MI beaded fibers revealed a lower burst rate and a more sustained release when compared to control fibers. Magnetic control of the MI beaded fibers was successfully tested by following selected waypoints along a star-shaped predefined trajectory. This study innovatively combines molecular imprinting technology with magnetic microrobots enabling targeted drug delivery systems that offer precise motion control via the magnetic response of microrobots along with selective uptake of a drug into the microrobot using MI beaded fibers in future.

Traditional materials for thermoelectric such as bismuth telluride have been studied and utilized commercially for the last half century, but recent advancements in materials selection are one of the principal function of the active thermoelectric device as it determines the reliability of the fabrication regarding technical and economic aspects. Recently, many researcher's efforts have been made to utilize oxide nanomaterials for wearable thermoelectric power generator (WTPG) applications which may provide environmental stable, mechanical flexibility, and light weight with low cost of manufacturing. In precise, fabric containing oxide metals have shown great promise as P−/N-type materials with improved transport and UV shielding properties. On the other hand, we have focused on ZnO nanostructures as a high-efficiency WTPG material because they are non-toxic to skin, inexpensive and easy to obtain and possess attractive electronic properties, which means that they are available for clothing with low-cost fabrication. To our observation, we are chaptering about the thermoelectric properties of ZnO and their composite nanostructures coated cotton fabric via the solvothermal method for the first time.
