EstATII is an esterase that a halotolerant, thermophilic and resistant to a spectrum of heavy metals including toxic concentration of metals. It was isolated from the lowest convective layer of the Atlantis II Red Sea brine pool. The Atlantis II brine pool is an extreme environment that possesses multiple harsh conditions such as; high temperature, salinity, pH and high concentration of metals, including toxic heavy metals. A fosmid metagenomic library using DNA isolated from the lowest convective layer this pool was used to identify EstATII. Polynucleotides encoding EstATII and similar esterases are disclosed and can be used to make EstATII. EstATII or compositions or apparatuses that contain it may be used in various processes employing lipases/esterases especially when these processes are performed under harsh conditions that inactivate other kinds of lipases or esterases.

A gold nanoparticle-based assay for the detection of a target molecule, such as Hepatitis C Virus (HCV) RNA in serum samples, that uses positively charged gold nanoparticles (AuNPs) in solution based format. The assay has been tested on 74 serum clinical samples suspected of containing HCV RNA, with 48 and 38 positive and negative samples respectively. The developed assay has a specificity and sensitivity of 96.5% and 92.6% respectively. The results obtained were confirmed by Real-Time PCR, and a concordance of 100% for the negative samples and 89% for the positive samples has been obtained between the Real-Time PCR and the developed AuNPs based assay. Also, a purification method for the HCV RNA has been developed using HCV RNA specific probe conjugated to homemade silica nanoparticles. These silica nanoparticles have been synthesized by modified Stober method. This purification method enhanced the specificity of the developed AuNPs assay. The method can detect a target molecule, such as HCV RNA in serum, by employing modified silica nanoparticles to capture the target from a biological sample followed by detection of the captured target molecule using positively charged AuNPs. The assay is simple, cheap, sensitive and specific. Another aspect of the invention is anisotropic silver nanoparticles and methods of their use.

In general the present disclosure relates to Nylon 6/montmorillonite clay nanocomposites with enhanced mechanical properties that have been prepared primarily by solution compounding. A major challenge in producing the Nylon 6/montmorillonite clay nanocomposites is associated with the exfoliation and dispersion of the clay particles within the polymer matrix. This disclosure presents compositions and methods for obtaining highly or fully exfoliated nylon 6/montmorillonite nanocomposites not only for organically modified clays with known compatibility with nylon 6 (Cloisite 30B), but also for clays with low/no compatibility with nylon 6 (Cloisite 15A and NaMMT) through solution compounding.
