In this work, we first report a facile, low-cost and high-throughput method for photolithographical fabrication of microfluidic cloth-based analytical devices (μCADs) by simply using a cotton cloth as a substrate material and employing an inexpensive hydrophobic photoresist laboratory-formulated from commercially available reagents, which allows patterning of reproducible hydrophilic-hydrophobi...

Colon targeted delivery systems of metronidazole (MTZ) based on osmotic technology were developed. The developed systems consisted of osmotic core (drug, osmotic agent and wicking agent), coated with semipermeable membrane (SPM) containing guar gum as pore former, coated core were then further coated with enteric coating to protect the system from acidic environment of stomach. The effect of va...

In this paper, a plasma-induced hemi-wicking phenomenon observed on hydrophobic sanded polymer surfaces, polypropylene (PP), polyethylene terephthalate (PET) and (PE) is reported. An atmospheric-pressure argon plasma jet was used to treat limited area of the carefully surfaces induce phenomenon. Such triggered by activation different from traditional type, which achieved purely surface topograp...

Abstract Wetting functionalities of rough surfaces are largely determined by the Laplace pressure generated across liquid–gas interfaces formed within surface structures. Typically, wetting create negative pressures, enabling capillary wicking, while non‐wetting positive exhibiting fluid repellency. Here, with microfabricated reentrant structures, it is shown that same can exhibit either a or p...

Abstract Liquid transport (wicking) has great effect on the physiological comfort, since it directly determines moisture management of fibrous assemblies. For elastic fabric structures, wickability primarily depends several factors, such as tensile strain and ambient conditions (e.g., temperature, relative humidity). The main purpose this work was to systematically clarify effects water tempera...
