This book provides in-depth knowledge about the fabrications,
structures, properties and applications of three outstanding
electrochemically engineered nanoporous materials including porous
silicon, nanoporous alumina and nanotubular titania. The book
integrates three major themes describing these materials. The first
theme is on porous silicon reviewing the methods for preparation by
electrochemical etching, properties and methods for surface
functionalization relevant for biosensing applications. Biomedical
applications of porous silicon are major focus, described in
several chapters reviewing recent developments on bioanalysis,
emerging capture probes and drug delivery. The second theme on
nanoporous alumina starts with describing the concept of
self-organized electrochemical process used for synthesis nanopore
and nanotube structures of valve metal oxides and reviewing recent
development and progress on this field. The following chapters are
focused mainly on optical properties and biosensing application of
nanoporous alumina providing the reader with the depth of
understanding of the structure controlled optical and photonic
properties and design of optical biosensing devices using different
detection principles such as photoluminescence, surface plasmon
resonance, reflective spectrometry, wave guiding, Raman scattering
etc. The third theme is focused on nanotubular titania reviewing
three key applications including photocatalysis, solar cells and
drug delivery. The book represents an important resource for
academics, researchers, industry professionals, post-graduate and
high-level undergraduate students providing them with both an
overview of the current state-of-the-art on these materials and
their future developments.
This book gives detailed information about the fabrication,
properties and applications of nanoporous alumina. Nanoporous
anodic alumina prepared by low-cost, simple and scalable
electrochemical anodization process due to its unique structure and
properties have attracted several thousand publications across many
disciplines including nanotechnology, materials science,
engineering, optics, electronics and medicine. The book
incorporates several themes starting from the understanding
fundamental principles of the formation nanopores and theoretical
models of the pore growth. The book then focuses on describing soft
and hard modification techniques for surface and structural
modification of pore structures to tailor specific sensing,
transport and optical properties of nano porous alumina required
for diverse applications. These broad applications including
optical biosensing, electrochemical DNA biosensing, molecular
separation, optofluidics and drug delivery are reviewed in
separated book chapters. The book appeals to researchers, industry
professionals and high-level students.
Expert authors from around the world contribute comprehensive,
up-to-date reviews on the current state of our knowledge of
bacterial endospores.

Recently, several electrochemical approaches have made it possible
to modify the original structure of such nanoporous materials as
nanoporous alumina or porous silicon. The pore structure of these
nanostructures can be modified to generate many innovative pore
architectures. Some examples of this are funnel-like, modulated,
serrated-like, hierarchical, three-dimensional, tip-like and
multilayered nanopores. This brings an excellent opportunity to
design and fabricate nanoporous materials and structures with
outstanding features and performances for multiple biotechnological
purposes (e.g. cell culture, molecular separation-adsorption, drug
delivery, optical sensing and so on). This book summarises the most
relevant advances in structural engineering of nanoporous anodic
alumina and porous silicon achieved by electrochemical approaches
for biotechnological applications.
Several structural engineering strategies are applied to develop
innovative templates based on nanoporous anodic alumina. These
templates are subsequently used to develop other nanostructures
based on certain materials with multiple applications such as
polymers, magnetic metals and semiconductors. These replicated
nanostructures could be integrated in various types of nanodevices
(e.g. nanoelectrodes for direct deposition of nanoparticles from a
gas draught, bulk-heterojunction solar cells, one-dimensional
optoelectronic devices, nanofilters and so on). It is expected that
the results presented will become a starting point to develop new
nanodevices and applications in a wide range of research fields.
