“…Recent studies demonstrated the suitability of the P. putida test in offering repeatable and precise biodegradability data [12,24]. In the present study, this method was used to follow biodegradability enhancement caused by the photo-Fenton treatment in order to find the optimum combination between the AOP and biological oxidation.…”

“…Pseudomonas putida bacterium is used as a representative of fresh water heterotrophic microorganisms. A standardised test method [18] is used to determine the inhibitory effect of surface water, ground water, waste water, water soluble chemicals, compounds and mixtures, as well as to assess the efficiency of waste water treatment and bioremediation processes [19][20][21].…”

Sensitivity of bacterial vs. acute Daphnia magna toxicity tests to metals

et al. 2009

The objectives of this study were to evaluate the sensitivity of two bacterial tests commonly used in metal toxicity screening — the Vibrio fischeri bioluminescence inhibition test and the Pseudomonas putida growth inhibition test — in comparison to the standard acute Daphnia magna test, and to estimate applicability of the selected methods to the toxicity testing of environmental samples. The D. magna acute test proved to be more sensitive to cadmium (Cd), zinc (Zn) and manganese (Mn) than the two bacterial assays, whereas P. putida seems to be the most sensitive species to lead (Pb). Manganese appears to be slightly toxic to D. magna and non-toxic to the two selected bacteria. This leads to the conclusion that even in regions with high background concentrations, manganese would not act as a confounding factor. Low sensitivity of V. fischeri to heavy metals questions its applicability as the first screening method in assessing various environmental samples. Therefore, it is not advisable to replace D. magna with bacterial species for metal screening tests. P. putida, V. fischeri and/or other bacterial tests should rather be applied in a complex battery of ecotoxicological tests, as their tolerance to heavy metals can unravel other potentially present toxic substances and mixtures, undetectable by metal-sensitive species.

“…TiO 2 NTs are known to be biocompatible and in recent years TiO 2 NTs have been explored for their potential use as in vivo photodecomposition catalysts, coatings for medical implants, augmentation of periimplant bone formation in vivo, and gene and drug delivery carriers. 22,34,74,84,88,101,104 More recently, Lee and coworkers have exploited the optical properties of TiO 2 NTs for use as potential therapeutic agents for cancer photothermal therapy in combination with NIR light. 30,45 TiO 2 NTs were produced by electrochemical anodization of Ti thin foils in an electrolyte consisting of ammonium fluoride and water in ethylene glycol at 60 V for 17 h. 113 An SEM image of the TiO 2 NTs is .…”

Tunable Nanostructures as Photothermal Theranostic Agents

2011

View full text Add to dashboard Cite

The theranostic potential of several nanostructures has been discussed in the context of photothermal therapies and imaging. In the last several decades, the burden of cancer has grown rapidly, making the need for new theranostic approaches vital. Lasers have emerged as promising tools in cancer treatment, especially with the advent of photothermal therapies wherein light absorbing dyes or plasmonic gold nanoparticles are used to generate heat and achieve tumor damage. Recently, photoabsorbing nanostructures have materialized that can be employed in conjunction with lasers in the near-infrared region in order to enhance both imaging and photothermal effects. The incorporation of tunable nanostructures has resulted in improved specificity in cancer treatment. Silica-cored gold nanoshells and gold nanorods currently serve as the chief plasmonic structures for photothermal therapy. Although gold nanorods and silica-cored gold nanoshells have shown promise as therapeutic agents, over the past few years new nanostructures have emerged that offer comparable and even superior theranostic properties. In the present review, several theranostic agents and their impact on the development of more effective photothermal therapies for the treatment of cancer are discussed. These agents include hollow gold nanoshells, gold gold-sulfide nanoparticles, gold nanocages, carbon and titanium nanotubes, photothermal-based nanobubbles, polymeric nanoparticles and copper-based nanocrystals.
