The present study highlights the interdependence of ambient humidity levels on the electrical parameters of organic-inorganic hybrid composite based humidity sensor at varied AC frequencies of input signal. Starting from the bottom, the layer stack of the fabricated humidity sensor was 200-nm silver (Ag) thin film and 4 μm spun-coated PEPC+NiPC+Cu2O active layer. Silver thin films were deposite...

BACKGROUND Urinary tract infections (UTIs) are the most common nosocomial infection experienced by patients in United States hospitals and are responsible for significant morbidity and excess hospital costs. The purpose of this study was to determine the efficacy of a silver alloy, hydrogel-coated, urinary catheter in the prevention of catheter-associated UTI, to assess the cost effectiveness o...

Silver nanoparticles in the form of silver based chemicals trace back their origin to time immemorial since the dilute forms of silver nitrate were used in place of antibiotics before they dominated the field of medicine. But, it has now become necessary to explore the anti-microbial properties of silver based chemicals again due to the microbes gaining resistance against the wide range of pres...

Many experimental studies have documented the impact of microcystins (MC) on fish based on either intraperitoneal injection, or oral gavaging via the diet, but few experiments were conducted by MC exposure through natural food uptake in lakes. In this study, the phytoplanktivorous silver carp were stocked in a large pen set in Meiliang Bay of Taihu Lake where toxic Microcystis blooms occurred i...

PURPOSE The problem of infectious diseases and drug resistance is becoming increasingly important worldwide. Silver is extensively used as an anti-infective agent, but it has significant toxic side effects. In this regard, it is topical to develop new silver compounds with high biological activity and low toxicity. This work is aimed to study DNA damage and chromosomal aberrations in blood cell...

The phytochemical and pharmacological studies of leaf, bark and fruit extracts of Samadera indica were carried out on aqueous and methanolic extracts, obtained by soxhlet technique. The qualitative tests showed the presence of carbohydrates, proteins, phenolics, alkaloids, saponins, flavonoids, tannins and resins, whereas quantitative estimations of carbohydrate, protein, phenolics and tannins ...

ilver has good electric conductivity and solderability and possesses S excellent electric characteristics as a contact and is thus widely used for plating electronic industrial parts. A cyanide plating bath is most often used, but the cyanide compounds have strong toxicity and a large amount of the cost is rxpkd for securing safe working conditions and waste treatment. Because of this, many cya...

Sir, We read the article by Chopra on the increasing use of silverbased products with interest and we would like to make some observations. The title of the article asked whether there was cause for concern, and, understandably, the issue of resistance was raised in this respect. Chopra makes a case for using dressings that release high concentrations of silver in order to overcome this, yet, i...

Dear Editors, The recent letter to the journal entitled ‘Cytotoxicity of silver dressings – time to think and react’ by Nagoba et al. provides a stimulus to react and provide evidence that supports the safety of silver. It is acknowledged that laboratory and some animal data exist that show silver and indeed other antibacterial agents to have a deleterious effect on various cells that facilitat...
