Porous silicon has been investigated as a novel material for biomedical applications since the early 1990s. Owing to its low toxicity profile and unique properties, it has been utilized in a variety of manners, including biomedical imaging and sustained delivery applications discussed within. In the first portion of this dissertation, quantum confined domains of silicon were used as ratiometric fluorescent probes, in which the long-lived excited states were harnessed to generate wavelength-dependent quenching motifs. To further evaluate the performance of porous silicon as a biomedical imaging agent, it was then compared and contrasted against a series of luminescent silicon nanocrystals to probe which unique properties are intrinsic to all silicon nanocrystals and which are imbued during the fabrication process. Finally, porous silicon microparticles were used to sustain the delivery of hormonal progestins to develop injectable contraceptives with the goal of reducing maternal mortality rates in sub-Saharan Africa. Owing to the anisotropic dissolution of porous silicon, hydrophobic progestin molecules were able to be released from the porous particle host in a highly linear fashion and for longer periods of time than the unprotected controls. The progestins were incorporated into the porous particle via a technique known as melt casting, in which molten drug infiltrates and then recrystallizes within the porous structure. Strategies for melt casting thermally instable drugs were also explored. Particles containing segesterone acetate were found to be non-toxic and well tolerated in a cohort of adult female Sprague-Dawley rats over an extended period of time.

By means of electrochemical treatment, crystalline silicon can be permeated with tiny, nanostructured pores that entirely change the characteristics and properties of the material. One prominent example of this can be seen in the interaction of porous silicon with living cells, which can be totally unwilling to settle on smooth silicon surfaces but readily adhere to porous silicon, giving rise to great hopes for such future applications as programmable drug delivery or advanced, braincontrolled prosthetics. Porous silicon research is active in the fields of sensors, tissue engineering, medical therapeutics and diagnostics, photovoltaics, rechargeable batteries, energetic materials, photonics, and MEMS (Micro Electro Mechanical Systems). Written by an outstanding, well-recognized expert in the field, this book provides detailed, step-by-step instructions to prepare and characterize the major types of porous silicon. It is intended for those new to the fi eld. Sampling of topics covered: * Principles of Etching Porous Silicon * Etch Cell Construction and Considerations * Photonic Crystals, Microcavities, and Bragg Stacks Etched in Silicon * Preparation of Free-standing Films and Particles of Porous Silicon * Preparation of Photoluminescent Nanoparticles from Porous Silicon * Preparation of Silicon Nanowires by Electrochemical Etch of Silicon * Surface Modifi cation Chemistry and Biochemistry * Measurement of Optical Properties * Measurement of Pore Size, Porosity, Thickness, Surface Area The whole is backed by a generous use of color photographs to illustrate the described procedures in detail, plus a bibliography of further literature pertinent to a wide range of application fi elds. For materials scientists, chemists, physicists, optical physicists, biomaterials scientists, neurobiologists, bioengineers, and graduate students in those fields, as well as those working in the semiconductor industry.

For over 30 years, porous silicon as a material has been leveraged for its usefulness in biomedical and sensing applications. Its tunable structural features, low toxicity profile and readily modifiable surface render this material extremely useful for a wide variety of applications. By chemically modifying surface species, such as silicon hydrides and silicon oxides with silanes, the properties of porous silicon can be enhanced for its use for chemical sensing, biomedical imaging, and drug delivery. After a brief introduction to porous silicon materials, the first part of this dissertation details surface-modified porous silicon photonic crystals for the chemical sensing of toxic vapors and nerve agents. Chapter 2 utilizes a dual-peak porous silicon photonic crystal embedded with specific for the selective detection of hydrogen fluoride (HF), hydrogen cyanide (HCN), and the chemical nerve agent diisopropyl fluorophosphate (DFP). The pore walls are rendered hydrophobic with octadecylsilane to aid with the loading of the colorimetric molecules while being insensitive to humidity fluctuations. This provides a robust means to develop a remote detection system for chemical agents. Chapter 3 employs the same photonic crystal, modified, however, with a specialized protein-based gatekeeper that is rendered semi-permeable only in the presence of HCN. This is one of the first novel designs of a bio-inorganic sensor capable of detecting chemical agents with high specificity and precision. The second portion of the dissertation describes how surface-modified porous silicon nanoparticles can be applied in biomedical applications. The first project details the use of Anti-KIT protein DNA-aptamers decorated onto a fluorescently labelled porous silicon nanoparticle for the in vitro and in vivo imaging of gastrointestinal stromal tumors. This work provides an effective platform in which aptamer-conjugated porous silicon nanoparticle constructs can be used for the targeted imaging of KIT-expressing cancers. The final project utilizes hydrophobic porous silicon nanoparticles for the delivery of erucamide, a highly hydrophobic fatty acid amide, within the retina. By harnessing the versatility of porous silicon, erucamide's target cells and mechanism of neurotrophic action can be identified.
