Generally, it was used in many research fields including solid phase synthesis in organic chemistry (Cankařová et al. However, the concept of lab-in-a-syringe or lab-in-syringe (or in-syringe) analysis is much older. 2017) developed the assay where the reaction and detection pads were introduced directly into the syringe barrel. This work was then followed by Zor and Bekar (Zor and Bekar 2017) for discrimination of enantiomers. Interestingly, in 2015, the lab-in-a-syringe (LIS) assay in microfluidics based on the lateral flow assay in a holder connected to the syringe was introduced (Pauli et al. There are articles combining paper-based devices with foil or PDMS, including “classical” stereolithography procedures (Kamali et al. Moreover, the concept of paper-based microfluidics was broadening out by the combination of these devices with other devices and techniques known from “classical” microfluidics. These devices can be used for many purposes, as recently reviewed (Carrell et al. They are made from cheap materials, like paper or wax, with cheap procedures, like common printing, drawing by pencils, or ironing. The concept of low-cost microfluidics, introduced in 2007 (Martinez et al. Preparation of Hydrophilic Poly(L-Lactide) Electrospun Fibrous Scaffolds Modified with Chitosan for Enhanced Cell Biocompatibility.The development of simple, low-cost, and efficient methods and/or devices for bioanalysis is tremendously valuable for many application fields, including self-testing in medicine, non-professional assays for determination of food quality, and portable environmental testing.

It is found that the water contact angle (WCA) will decrease with an increase in the CS solution concentration and the coating time, which indicates that CS-coated PDMS scaffolds exhibit noticeable hydrophilicity compared with graded PDMS scaffold.įlemming R G, Murphy C J, Abrams G A, et al. Moreover, the graded chitosan (CS)-coated PDMS scaffolds were prepared by using dip-coating technique under low vacuum and their hydrophilicity was examined. The graded PDMS scaffold fabricated had a compressive modulus and a compressive strength of 19.69☑.42 kPa and 4.76☐.22 kPa, respectively. The results showed that the smaller the size of the NaCl particles is, the higher the porosity and water absorption of graded PDMS scaffolds would be. The properties of graded PDMS scaffolds, including porosity, water absorption, interconnectivity, compression modulus, as well as compression strength were investigated. Polydimethylsiloxane (PDMS) scaffold with an axial pore size grade was successfully manufactured via vacuum-assisted resin transfer moulding (VARTM) and particle leaching technologies. Graded porous scaffold can be applied to study the interactions between cells and scaffold with different pore sizes.
