We report on the development of photosensitizer-conjugated gold nanorods (MMP2P-GNR) in which photosensitizers were conjugated onto the surface of gold nanorods (GNR) via a protease-cleavable peptide linker. We hypothesized that fluorescence and phototoxicity of the conjugated photosensitizers would be suppressed in their native state, becoming activated only after cleavage by the target protea...

Cancer antigen 125 (CA 125) is a useful tumor marker with a threshold value of 35 U mL(-1) expressed by more than 80% of patients with non-mucinous epithelial ovarian cancer. In this work, a novel strategy for the analysis of CA 125 using the plasmon resonance scattering (PRS) properties of gold nanorods was proposed. The gold nanorod (GNR)-anti-CA 125 conjugates were prepared first. The immuno...

A prerequisite for future graphene nanoribbon (GNR) applications is the ability to fine-tune the electronic band gap of GNRs. Such control requires the development of fabrication tools capable of precisely controlling width and edge geometry of GNRs at the atomic scale. Here we report a technique for modifying GNR band gaps via covalent self-assembly of a new species of molecular precursors tha...

There has been growing interest in developing nanoelectronic devices based on graphene because of its superior electrical properties. In particular, patterning graphene into a nanoribbon can open a bandgap that can be tuned by changing the ribbon width, imparting semiconducting properties. In this study, we report the effect of ribbon width on electrical transport properties of graphene nanorib...

The use of carbon nanotubes (CNTs) as cylindrical reactor vessels has become a viable means for synthesizing graphene nanoribbons (GNRs). While previous studies demonstrated that the size and edge structure of the as-produced GNRs are strongly dependent on the diameter of the tubes and the nature of the precursor, the atomic interactions between GNRs and surrounding CNTs and their effect on the...

P A P ER Abstract The interaction of light with a single gold nanorod (GNR) depends strongly on the polarization and wavelength of the light. For isolated GNRs, the maximum of the polarization (wavelength)-dependent linear and nonlinear absorption appear at the same excitation polarization (wavelength). Here, it is demonstrated that these relationships can be manipulated in a GNR assembly compo...

Antibiotic resistance poses an increasingly grave threat to the public health. Of pressing concern, rapid spread of carbapenem-resistance among multidrug-resistant (MDR) Gram-negative rods (GNR) is associated with few treatment options and high mortality rates. Current antibiotic susceptibility testing guiding patient management is performed in a standardized manner, identifying minimum inhibit...

BACKGROUND Cryptococcus neoformans is an encapsulated yeast. There is still little quick and effective solution for the diagnosis or treatment of C. neoformans infection at an early stage in clinical. Antibody-conjugated silica-modified gold nanorods (GNR-SiO2-Ab) can conjugate C. neoformans selectively. It may provide a possibility for treatment of cryptococcosis safely and effectively. METH...

The negative differential resistance (NDR) of resonant tunneling diodes (RTDs) enables their use in fast-switching applications and logic circuit designs. So far, RTDs have been realized in Si/SiGe or IIIV compound material systems. However, various emerging devices have been proposed and studied in the past two decades. Recently, graphene nanoribbons (GNRs) have attracted much attention as the...
