Parametric Design, Modeling, and Optical Evaluation of Retroreflective Prismatic Structures
Retroreflectors (RR) are defined as passive optical structures that redirect incident light to its originating source. Specific types of retroreflectors called inverted cubes (ICs) function through total internal reflection (TIR) and are used in various applications such as measurement tools, …

Lunar Laser Ranging for Autonomous Cislunar Spacecraft Navigation
… $L_1$. This method uses existing lunar ranging retroreflectors (LRRR) installed on the Moon's surface in the 1960s and 1970s. A spacecraft can make laser ranging measurements to the LRRR to estimate its orbit states. A simulation platform was created to test this concept in the circular …

Immunological and Molecular Techniques for Point-of-Care Diagnostics
… assay used embedded, microfabricated linear retroreflectors as bio-sensing surfaces and micron-sized magnetic particles as light-blocking labels in a semi-homogeneous format, resulting in a highly sensitive diagnostic immunoassay. The magnetic properties of the particle labels were useful in …

Microfabricated Surfaces and Particles for Advanced Immunoassay Platforms and High-Efficiency Electrowetting Heat Transfer System
… conorii. We simplified the process of micro-retroreflectors fabrication, developing an experimental procedure based on commercial photolithographic techniques. Our collaborators found that the limit of detection of this platform is 4000 R. conorii bacteria per mL in buffer, which is …

Lithographically Fabricated Micro-Reflectors for Sensitive Point of Care Diagnostics
Timely diagnosis and treatment of infectious diseases calls for highly sensitive diagnostic assays. Traditional diagnostic methods include microscopy, polymerase chain reaction (PCR), immunofluorescence (IF) and enzyme-linked immunosorbent assay (ELISA). Many of these diagnostic methods, however, …
