Nanotubes for the Future

In February 2007, UPRM PREM hosted more than 140 students, members of the five Materials Science and Engineering clubs formed in public schools under the auspices of PREM. The activity was organized by PREM’s Office of Outreach and Education led by Prof. J. Santos and was partly financed b

Gold Nanoparticle Based FRET Asssay for Detection of DNA Cleavage

This represents the first nanoparticle-based fluorescence assay for probing single-strand DNA nuclease activity. Our simple assay with extremely high sensitivity will make it widely applicable and highly useful for convenient characterization of DNA/RNA cleavage reactions Given the simplic

Very Large Infrared Two-Photon Absorption Cross Section of Asymmetric Zinc Porphyrin Aggregates: Role of Intermolecular Interaction and Donor-Acceptor Strengths

One of the long-standing challenges is the development of organic compounds, which exhibits a large value of the 2PA cross section at wavelength(s) above 700 nm. We have designed a series of D-A Zn-porphyrin aggregates that possess exceptionally large Two Photon Absorption (TPA) cross se

Magnetic Bead Assays

Certain antibiotics bind to specific receptors on bacterial cell walls blocking further growth and eventually leading to the bacterial death. Dr. Menake Piyasena (PREM Post-doc fellow) at CSULA has demonstrated a bead-based technique on a microfluidic format that can be used to monitor ba

Molecules that Like Each Other

Scientists who understand the nature of a stabilizing force between molecules, or between parts of the same molecule, can incorporate this force systematically into the design of new materials. This molecular engineering can result in unique and beneficial stability or functionality. The
