Noble metal nanoparticles hold great potential as optical contrast agents due to a unique feature, known as the plasmon resonance, which produces enhanced scattering and absorption at specific frequencies. The plasmon resonance also provides a spectr

We present a fast wide-field holography system for detecting the photothermally excited gold nanospheres in a QPI scheme. An interferometric optical lock-in approach was shown to improve SNR for detecting nanoparticles on multiple substrates.

Effective treatment of patients with malignant brain tumors requires surgical resection of a high percentage of the bulk tumor. Surgeons require a method that enables delineation of tumor margins, which are not visually distinct by eye. In this study

The dimerization of receptors on the cell membrane is an important step in the activation of cell signaling pathways. Several methods exist for observing receptor dimerization, including coimmunoprecipitation, chemical cross-linking, and fluorescence

Gold nanorods are candidates for tumor delineation due to their unique optical properties and biocompatibility. The optical characteristics of nanorods are tuned during synthesis. Anti-EGFR nanorods effectively label tumors within brain slices.

Single gold nanospheres sense local dielectric environment but are influenced by plasmonic coupling of proximal pairs. Polarization control separates these two effects, allowing both RI sensing and measurement of interparticle distance, with potentia

This work presents simultaneous imaging and detection of three different cell receptors using three types of plasmonic nanoparticles (NPs). The size, shape, and composition-dependent scattering profiles of these NPs allow for a system of multiple dis

We propose the use of polarization mapping as a tool to better separate the effects of plasmonic coupling from the local refractive index for molecular imaging and biosensing using gold nanoparticles. Polarization mapping allows identification of the
