“…This membrane demonstrated selective antibody binding, and could be used for hIgG purification from a simulated cell culture supernatant. Lequieu et al[263] prepared a thermo-responsive PNVCL onto poly(ethylene-terephtalate) (PNVCL-PET) composite membrane for sizebased separation of a macromolecular mixture. First, a photo-reactive azidophenyl group was incorporated into the thermo-responsive PNVCL chains.…”

“…42 43 46 In the 1960's, PNVCL was utilized in multi-layered glass materials as a separation material in specific membranes and as an ingredient in the wound-healing film. 47 For controlled delivery applications, researchers have studied the self-assembling thermoresponsive containers which are contagious of slim films of PNVCL that are settled onto porous support membranes. Recently, with the aid of PNVCL's selective determination, some of the opiate drugs in aqueous media has been achieved.…”

Thermoresponsive polymers have been attractively and scientifically significant in the recent years due to the utilization of various pharmaceutical and biomedical formulations. Poly(N-vinylcaprolactam) (PNVCL) is a temperature-responsive polymer, only second to poly(N-isopropylacrylamide) (PNIPAM), the most popular temperature-responsive polymer. PNVCL should be considered an important focus due to the phase transition temperature of such polymer that is close to the physiological temperature. PNVCL is a polymer which offers unrivaled qualities for different potential medical device applications. Specifically, it offers one kind of thermoresponsive abilities, which satisfies the material innovation imperatives required in focused drug delivery applications. PNVCL and PNIPAM polymers are well-studied thermoresponsive abilities since its lower critical solution temperature (LCST) is near the physiological temperature and has mostly been used in biomedical applications. Therefore, it can be investigated as a potential candidate for pharmaceutical utilization. This review highlights a comparison of PNVCL with PNIPAM regarding comparable characteristics which also delve into selected examples and the most recent published of applications based on PNVCL with a specific focus on drug delivery system. The consequence exhibits that the PNVCL will play a pivotal role in nanotechnology and the environment.

“…25 Several surface 'grafting from' techniques have been reported in the literature, including chemical grafting, 25 plasma, 24,26 radiation 13,19,27,28 and photoinduced grafting. 29,30 A previously reported plasma-induced grafting technique 24 was chosen for the grafting of PNIPAM to the PCTEPMs because it presented several advantages to incorporating the desired properties into the PC membrane. Plasma-induced grafting allows control over the location of the grafting of the PNIPAM chains, either on the membrane surface or on the walls of the pores.…”

The development of porous membranes that can rapidly change flow rates in response to external, noninvasive stimuli has broad technological applications for areas ranging from biomedical devices to architecture. Environmentally responsive membranes have a fundamental role in the development of devices used in chemical sensors, biological sorters, sequencing, separations, high-throughput medical devices and labs on a chip. The design and engineering of these responsive porous membranes have been achieved through the coupling of porous membranes with polymeric materials that can change their physical conformation in response to pressure, heat, pH or different chemical entities. Inspired by the phototropic growth of coleoptiles and the light-mediated mechanism that plants use to open their stomata, in this work, light-responsive porous membranes were engineered, mathematically modeled and synthesized. This biologically inspired approach led to a state-of-the-art design technique and a device that outperforms its natural counterpart and is capable of reversibly controlling flow rates from 0.001 to 0.035 ml s À1 cm À2 in less than a few minutes using the noninvasive stimulus of light. We envision that the polymeric responsive membranes and the platform synthesis technique employed in this manuscript for their fabrication could be utilized in a broad range of applications and will have a great impact on the fields of fluid handling, biomedical high-throughput devices, sensors, medicine and other fields of chemistry, biology and mechanical engineering.
