Visual optical biosensors based on DNA-functionalized polyacrylamide hydrogels.

Biosensors are devices that can provide quantitative or semi-quantitative analytical information about target molecules, where molecular recognition is based on biomolecular interactions. In recent years, DNA has emerged as a useful molecule for biosensor development since DNA can not only recognize its complementary strand, but also metal ions, small molecules, proteins and cells utilizing DNA...

Enzyme Immobilization: The Quest for Optimum Performance

Immobilization is often the key to optimizing the operational performance of an enzyme in industrial processes, particularly for use in non-aqueous media. Different methods for the immobilization of enzymes are critically reviewed. The methods are divided into three main categories, viz. (i) binding to a prefabricated support (carrier), (ii) entrapment in organic or inorganic polymer matrices, ...

Optimization of Lipase Immobilization

Pseudomonas aeruginosa BBRC-10036 was used for lipase production. The organism secreted the enzyme extracellulary. In order to purify the enzyme, precipitation was done first, and then this lipase has been purified by Ion exchange Chromatography leading to 2.3-fold purification and 11.47% recovery. Lipase from P.aeruginosa was entrapped into Ca-alginate gel beads and effect of independent varia...

Optimization of Candida rugosa lipase immobilization parameters on magnetic silica aerogel using adsorption method

Magnetic silica aerogel in hydrophobic and hydrophilic forms were used as support to immobilize Candida rugosa lipase by adsorption method. Response surface methodology (RSM) was employed to study the effects of the three most important immobilization parameters, namely enzyme/support ratio (0.3-0.5, w/w), immobilization time (60-120 min) and alcohol percentage (20-40, %v/v) on the specific act...
