This study was conducted  to evaluate the antifungal effects of garlic (Allium sativum) and wormwood (Artemisia sieberia) 80-85% purity ethanolic extracts on rainbow trout (Oncorhynchus mykiss) eggs incubation and larvae survival rate. The experimental group divided to three different doses of garlic (50,100,200 ppm), wormwood (25, 50, 100 ppm), green malachite (2 ppm) as positive control group...

Mercury ions (Hg(2+)) can specifically interact with the thymine-rich Hg(2+) aptamer and malachite green (MG) to form the Hg(2+) aptamer-MG-Hg(2+) complex, inducing the increase of resonance scattering (RS) intensity at 611 nm, which enables the label-free detection of Hg(2+) in aqueous solution with high selectivity and a detection limit of 1.7 nM.

By oxidation-reduction assay, the viability of Mycobacterium tuberculosis in sputum specimens was evaluated. The technique is based on the Alamar Blue and Malachite Green dyes, which change their color in response to M. tuberculosis growth. The method is simple, permits visual reading of results, and is applicable for laboratories with limited resources.

A molecule or a molecular system always consists of excited states of different spin multiplicities. With conventional optical excitations, only the (bright) states with the same spin multiplicity of the ground state could be directly reached. How to reveal the dynamics of excited (dark) states remains the grand challenge in the topical fields of photochemistry, photophysics, and photobiology. ...

In this work, two low-cost wastes, bivalve shell (BS) and Zea mays L. husk leaf (ZHL), were investigated to adsorb malachite green (MG) from aqueous solutions. The ZHL was treated with calcined BS to give the BS-ZHL, and its ability to adsorb MG was compared with untreated ZHL, calcined BS and Ca(OH)(2)-treated ZHL under several different conditions: pH (2-8), adsorbent dosage (0.25-2.5 g L(-1)...

In this study, we have reported the green synthesis magnesium ferrite using tragacanth gel by the sol-gel method without using any organic chemicals. The sample was characterized by powder X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), vibrating sample magnetometer (VSM) and scanning electron microscopy (SEM). The X-ray powder diffraction (XRD) analysis revealed the fo...
