Hydrogel-free and Pump-less Microfluidic Device for Bacterial Chemotaxis under Chemical Gradient
نویسندگان
چکیده
We present a static microfluidic device without use of hydrogel barrier for the generation of chemical gradient. The microfluidic device allows for the analysis of bacterial chemotaxis without use of hydrogel, membrane, and pump. We demonstrate a chemotactic response to attractant and repellent by measuring of dynamic change of bacterial population in detection area. In this chemotaxis assay, bacterial chemotaxis obviously shows different behaviors as chemoeffectors and concentrations.

Bacterial chemotaxis in linear and nonlinear steady microfluidic gradients.
Diffusion-based microfluidic devices can generate steady, arbitrarily shaped chemical gradients without requiring fluid flow and are ideal for studying chemotaxis of free-swimming cells such as bacteria. However, if microfluidic gradient generators are to be used to systematically study bacterial chemotaxis, it is critical to evaluate their performance with actual quantitative chemotaxis tests....
متن کاملMicrofluidic chip containing porous gradient for chemotaxis study
We have developed a new porous gradient microfluidic device based on in situ Gtn-HPA/CMC-Tyr hydrogel that comprises gelatin hydroxyphenylpropionic acid (Gtn-HPA) conjugate and carboxymethyl cellulose tyramine (CMC-Tyr) conjugate. The device is fabricated using a soft lithographic technique, in which microstructures were patterned on a thin layer of polydimethylsiloxane (PDMS) using a polymeric...
متن کاملA three-channel microfluidic device for generating static linear gradients and its application to the quantitative analysis of bacterial chemotaxis.
We have developed a prototype three-channel microfluidic chip that is capable of generating a linear concentration gradient within a microfluidic channel and is useful in the study of bacterial chemotaxis. The linear chemical gradient is established by diffusing a chemical through a porous membrane located in the side wall of the channel and can be established without through-flow in the channe...
متن کاملMicrofluidics for bacterial chemotaxisw
Microfluidics is revolutionizing the way we study the motile behavior of cells, by enabling observations at high spatial and temporal resolution in carefully controlled microenvironments. An important class of such behavior is bacterial chemotaxis, which plays a fundamental role in a broad range of processes, including disease pathogenesis, biofilm formation, bioremediation, and even carbon cyc...
متن کاملGeneration of complex, static solution gradients in microfluidic channels.
A microfluidic device is used to generate a complex gradient of diffusible molecules in a static solution. The gradient is precise and steady both in space and in time. This device, made from poly(dimethylsiloxane), consists of three layers. The molecules in reservoirs on the top layer diffuse through the flat middle layer of hydrogel and reach an equilibrium distribution. Microfluidic channels...
