RNA-based applications requiring high-quality, non-degraded RNA are a foundational element of many research studies. As such, it is paramount that the integrity of experimental RNA is validated prior to cDNA synthesis or other downstream applications. In the absence of expensive equipment such as microfluidic electrophoretic devices, and as an alternative to the costly and time-consuming standa...

In this paper, carbon nanotubes (CNTs) were added into chitosan (CS) hydrogels in the form of chitosan modified CNTs (CS-CNTs) composites to prepare carbon nanotubes hydrogels (CNTs-GEL). The products, named CS-MWCNTs, were characterized by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy. Swelling properties and effect of pH on controlled release performanc...

In this paper, preparation method of unsymmetrical di-methyl hydrazine with nano aluminum particles (50 and 130 nm) has been investigated. One of the important aspects of the research is the uniform dispersion of the nano particles in the fuel gel. Homogeneity of the fuel influences the quality of propellant combustion. The results showed that the combination of ultrasonic-mechanical-magnetic a...

Bigels are unique two-phase systems that have recently been presented as a structured method for active ingredient application. The purposes of the current study were to develop and characterize bigel formulations containing loxoprofen. They benefits both hydrogel organo-gel. In order enhance penetration, pluronic lecithin was added form organo-gel, HPMC hydrogel, which properly hydrates stratu...

Pulsed field gel electrophoresis (PFGE) is capable of resolving large DNA molecules of up to two million nucleotides and is becoming a widely used technique in DNA studies (1—3). Three factors can potentially limit PFGE in a laboratory: 1. the cost of the apparatus, 2. reproducibility of electrophoretic conditions, and 3. unusually long electrophoretic time. To alleviate some of these problems ...

This protocol describes a method for in-gel digestion of proteins after fractionation using SDS-PAGE. It is applicable to both oneand two-dimensional polyacrylamide gels of different thicknesses, acrylamide concentrations, and band (spot) sizes. This protocol followed by liquid chromatography/mass spectrometry/mass spectrometry (LC-MS/MS) or matrix-assisted laser desorption/ionization/time of f...

Microfluidic chips are powerful tools for biochemical experiments. High speed and precise flow control can be achieved by using microvalves on a chip. Several types of microvalves that can be integrated into a microfluidic chip have been reported. Among them, gel microvalves have certain advantages over other valves because of their soft structure, which will contribute to prevent mechanical da...

This paper proposes a model for predicting dynamic motions of elastic robots made entirely of electro-active polymer gel. The requirement is that both active and passive deformations be described simultaneously. Active deformations arise from generated stress, while passive deformations are due to external forces, such as gravity and friction. We represent both in the same framework, considerin...
