In this work a 1,2,4‐triazole derivative 1‐(4‐aminobenzyl)‐1,2,4‐triazole (abtz) was utilized, one new cadmium(II) coordination polymer, namely [Cd(abtz)I2]n (1) was prepared through the powerful solvo‐thermal synthetic strategy. In compound 1, the abtz building blocks are interlinked through the central CdII ions forming the two‐dimensional (2D) layer coordination framework. Powder X‐ray diffraction (PXRD) characterization also reveals that we have prepared the pure phases of coordination polymer 1. Optical properties have been determined, which can behave the excellent photo‐luminescent emission of coordination polymer 1. Photo‐luminescent experiment also reveals that coordination polymer 1 can behave the highly sensitive detection for acetone molecules with high Ksv value (Ksv = 4.12 ×104 L·mol–1) in the recyclable detection fashion. Additionally, coordination polymer 1 also can behave the highly sensitive detection for pollutant dichromate with excellent quenching efficiency Ksv (Ksv = 2.12 × 104 L·mol–1) and low detection limit [38 × 10–3 mM (S/N = 3)]. UV/Vis, photo‐luminescent lifetime, and PXRD patterns also have been determined to analyze the detection mechanism.

“…The peaks at 1221 cm −1 was corresponded to the stretching vibration of the C-N bonds. The bands at 1163 cm −1 and 1068 cm −1 represented the stretching vibration of the C-O-C groups [38,39]. In addition, there were no characteristic peaks at 1687 cm −1 and 1071 cm −1 which demonstrated that there were no residues of DMF and THF in the PU electrospun nanofibrous membrane.…”

“…The band around 1715 cm −1 was the characteristic peak of acetone, which can be attributed to the stretching vibration peak of the C=O group [35]. The peaks at 1050 cm −1 , 1232 cm −1 , 1369 cm −1 , and 1743 cm −1 of the CA membrane spectra can be assigned to the stretching vibrational peak of the C-O skeleton in ether group, stretching vibration of C-O-C bond, stretching vibration peak of C-CH 3 , and the stretching vibration of the C=O group, respectively [36][37][38]. Moreover, there were no characteristic peaks at 1687 cm −1 and 1715 cm −1 , indicating that there was no DMF and acetone solvent residues in the as-prepared CA electrospun nanofibrous membrane.…”

Novel hydrophobic/hydrophilic Janus fibrous membranes, the poly[4,4 -methylenebis (phenylisocyanate)-alt-1,4-butanediol/di(propylene glycol)/plycaprolactone] (PU) fibrous membrane as the hydrophobic layer and cellulose acetate (CA) fibrous membrane as the hydrophilic layer, were fabricated by the so-called "layer-by-layer" electrospinning technology. A series of the PU/CA Janus membranes with different electrospinning time of the CA layers by which the thickness of hydrophilic layer can be controlled were also prepared to uncover its influence on the directional water vapor transmission. The results showed that water vapor transmission capability from the hydrophobic side to the hydrophilic side of the PU/CA Janus fibrous membrane was enhanced rather than that from the reverse direction of the same membrane. The optimal water vapor transmission capacity existed when the electrospinning time of CA fibrous membrane reached 15 min. Such enhanced water vapor transmission originated because of the asymmetric wettability of the Janus membrane and the strong force to draw tiny water droplet from the hydrophobic side to the hydrophilic side. The novel understanding is useful for facile designing and fabrication of efficient moisture permeable fabrics and clothing.

“…The hydrophilicity of cellulose acetate and hydrophobicity of coaxial polyurethane caused the loading of cargo drug in the latter due to the poor affinity of the drug with water. Notably, the encapsulated drug displayed two-stage release kinetics from the cellulose acetate-polyurethane coaxial electrospun fibers [110].…”

The polysaccharide-based advanced drug delivery system owing to their biocompatibility, ability to encapsulate the drug molecules in their interspaces, and ability to achieve a controlled release of the cargo drug molecules result in improved drug pharmacokinetics. The drug-loaded polysaccharides possess ability to evade the multidrug-resistant microbial efflux pumps by aggregation effect, whereas the drug loaded polysaccharidefabricated metal nanoparticles present an exceptional candidature for effectively transporting the drug molecules across the membrane barriers while enabling the theranostic applications at the same time. The biodegradability of polysaccharide based drug delivery systems ensure a sustained release of the encapsulated drug molecules, which minimizes the side effects caused by a burst release of the cargo therapeutics. These drug delivery systems proved highly beneficial for the NSAIDs that otherwise manifest ulcerogenic effect in the gastrointestinal tract. The large surface area of polysaccharides further provide a higher drug-loading capacity, which maintains the optimal concentration of the cargo drug at the target sites. The emerging applications of biodegradable polysaccharides in the designing of multicompartmental microspheres revolutionized tissue engineering, multi drug delivery, and cell culturing technologies. The present review deals with the current-status of polysaccharides as advanced drug delivery systems.
