It is not so far from now, although it is just the end of the XX century, the
time when we discussed outlooks of the use of biotechnologies in medicine and
pharmacy. These hopes were connected mainly with new microbiological products
and new materials (polymers) for pharmaceutics, biomedicine and organ transplantation.
Now in the XXI century, we are much more enthusiastic about outlooks
of nanotechnologies for our life and environment.
The book "Biotechnology of Biopolymers" comprises 17 chapters covering occurrence, synthesis, isolation and production, properties and applications, biodegradation and modification, the relevant analysis methods to reveal the structures and properties of biopolymers and a special section on the theoretical, experimental and mathematical models of biopolymers.
The extracellular matrix (ECM) represents a complex organization of macromolecules
that surrounds the cell and comprises the substratum onto which the cell
may be attached. The properties and functions of the ECM depend ultimately on
its structure, molecular components, architecture, and dynamic modulation.
Because the critical role of ECM involved in cell biology and physiology has long
been recognized, the structure and biology of the ECM have been extensively
studied (Yurchenco and Birk 1994 ; Ayad et al. 1998 ; Robert 2001 ) .
In 1959, Richard P. Feynman, Professor of Physics at the California Institute of
Technology and Nobel Laureate, delivered an address at the American Physical
Society, which is given the credit for inspiring the field of nanotechnology. Published
in Engineering and Science, Feynman’s address entitled “Plenty of Room at the
Bottom” described a new field of science dealing with “the problem of manipulating
and controlling things on a small scale.
Trong năm tài chính năm 2001, NNI đã xác định được chín khu vực của những thách thức lớn (Khoa học Quốc gia và Hội đồng Công nghệ 2000). Nanobiotechnology và nghiên cứu nanobiomedical đã dần dần tăng lên trong tầm quan trọng (Viện Y tế năm 2000).
Nanobiotechnology is an emerging area of scientific and technological opportunity.
The terms ‘‘Nanobiotechnology’’ and ‘‘Bionanotechnology,’’ used interchangeably,
apply the tools and processes of nano/microfabrication to build
devices for studying or manipulating biosystems. The field is progressing
incredibly fast worldwide.
Biomolecule–nanoparticle (NP) [or quantum-dot (QD)] hybrid systems
combine the recognition and biocatalytic properties of biomolecules with
the unique electronic, optical, and catalytic features of NPs and yield com-posite materials with new functionalities.
Many people who today choose herbal products in lieu of
prescription medications assume that because these products
are natural, they must be safe, even when the evidence for this
assertion is essentially anecdotal. Recent studies have shown
that herbals are highly variable in quality and composition,
with many marketed products containing little of the intended
ingredients and containing unintended contaminants, such as
heavy metals and prescription drugs. A few herbals are banned
outright in several countries.
