Microorganisms naturally form biofilms on solid surfaces for their mutual benefits including protection from environmental stresses caused by contaminants, nutritional depletion or imbalances. The biofilms are normally dangerous to human health due to their inherited robustness. On the other hand, a recent study suggested that electrochemically active biofilms (EABs) generated by electrically a...

BACKGROUND Conventional ways of making bio-electrodes are generally complicated, expensive and unconformable. Here we describe for the first time the method of applying Ga-based liquid metal ink as drawable electrocardiogram (ECG) electrodes. Such material owns unique merits in both liquid phase conformability and high electrical conductivity, which provides flexible ways for making electrical ...

Trace metals occur during natural processes and are also obtained anthropogenic activities. Streams, lakes rivers surrounded by farmlands engaged in the use of metal-enriched fertilizers have shown a possible positive correlation to rise chemical, organic water-soluble for long period. there is tendency high correlations trace source waters. Furthermore, increasing level fish alarming has spurr...

Abstract To investigate the role of cow dung in soil reclamation and bio assimilation along with accumulation heavy metals earthworm (P. posthuma) (N=900) earthworms were used treatment groups CD-soil mixture different proportion designed. Nonlethal doses lead acetate cadmium chloride added groups. Mature P. posthuma released each experimental pot maintaining favorable conditions. The pH, carbo...

Chromium is a heavy metal toxic for plants that due extensive industrial applications over the last decade, has become a serious environmental pollution. On the other hand, chelator dissolution and absorption of metal by the plant increase and their use in phytoremediation is important. The aim of this study was to evaluate the effect of different concentrations of chromium and ethylene diamine...

Recently, significant advances have occurred in the development of phosphors for bio hybrid light-emitting diodes (Bio-HLEDs), which have created brighter, metal-free, rare-earth phosphor-free, eco-friendly, and cost-competitive features for visible light emission. Here, we demonstrate an original approach using bioinspired phosphors in Bio-HLEDs based on natural deoxyribonucleic acid (DNA)-cur...

Objectives: This report explores the possibility of synthesizing enzyme–metal–organic framework (MOF) composites by ink-jet printing. Results: This study demonstrates that the direct synthesis of patterned enzyme–metal–organic framework (MOF) composites on various substrates including paper and polymeric films can be readily achieved by ink-jet printing bio-inks containing protein molecules, me...

Recent progress in data mining research has led to the development of numerous efficient and scalable methods for mining interesting patterns in large databases. In the mean time, recent progress in biology, medical science, and DNA technology has led to the accumulation of tremendous amounts of bio-medical data that demands for in-depth analysis. The question becomes how to bridge the two fiel...

OBJECTIVE Bioremediation technology has gained importance because microbes could be the convenient source of bio-absorption/bioaccumulation of metals from effluent streams. METHODS The nickel-resistant bacterial isolates (NiRBI) were selected from various bacterial isolates from industrial effluent and grown in nutrient broth containing different concentrations of nickel sulfate (0.3-3.0 mmol...
