A surface-enhanced Raman spectroscopy (SERS)-active extraction column based on propanethiol modified silver dendrites was fabricated. The column, which combines the advantages of solid phase extraction and SERS, may facilitate the development of rapid analysis with high reliability and accuracy. High temporal stability (under a continuous and intensive laser radiation) and excellent repeatabili...
nothing affects learners more than assessment, so it is important to involve them in assessment process. involvment of learners in assessment helps them to become autonoumos learners. despite this importance iranian learners specialy javanroodian ones are not activily involved in the process. hence the aim of this thesis is to invesrtigate thier ability in th eassessment process
A whole-column detection (WCD) system was fabricated using the parts from a typical A4 size optical scanner. Optimum layout of the fluorescence tube, beam condenser and photon transducers from the scanner made an effective devise to examine the dynamic chromatographic separation process. This system was applied in monitoring peak crossover in an ion-pair chromatographic elution. A stage-wise gr...
Here we describe fast analysis of biomolecules by newly developed pressure-driven liquid chromatography (LC) on a chip with integration of a gradient elution system. We have reported the fabrication of a gradient elution system using a cross-Tesla mixer on a chip with pillar array columns [1]. In this study, we applied the chip to the analysis of biological compounds, and showed that 10 times f...
Background and Aim: Exposure to heavy metals always causes serious health problems in people working in the industry. Heavy metals may interfere with enzyme functioning or accumulate in specific body organs, leading to various health problems. Cadmium is a toxic heavy metal widely used in various industries and, therefore, workers in metal industries are at risk of exposure to it. Materials...
This work focuses on computer-assisted gradient elution method development in inorganic anion analysis of surface water using ion chromatography. An integral elution model was applied to model gradient retention behavior based on isocratic experimental information. Applied optimization strategy incorporates in-house developed elimination criteria for optimal condition search routine with gradie...

Background: In the setting of prosthetic joint infections treated with a two-stage procedure, spacers can be sonicated after removal. We hypothesize that the sonication process may cause an increased elution of antibiotics from the spacer, leading to elevated concentrations of antibiotics in the sonication fluid inhibiting bacterial growth. We aimed to evaluate in vitro the influence of sonicat...
the aim of this study is to investigate antibacterial effects of immunodominant proteins isolated from the venom of naja naja oxiana snake against staphylococcus aureus, escherichia coli, bacillus subtilis and pseudomonas aeruginosa.the innate immune system is an important line of defense against bacterial diseases. antibacterial proteins produced by snake venoms have recently attracted signifi...
