Overview of Biomaterials
1.1 Introduction
Human life is invaluable; however, quality and survival of life is greatly
affected by numerous factors, including medical complications caused by
diseased, damaged, or aged tissues or organs. These circumstances often call
for surgical treatments to repair, replace, maintain, or augment the functions
of affected tissues or organs using some additional functional components.
Traditionally, they have been treated with the help of tissues or organs procured
from patients or donors. Depending on the location of reimplantation
of the procured tissue (also known as graft), they are termed autograft,
allograft, or xenograft (see Figure 1.1).
If the graft is implanted in the same patient, it is termed autograft and if
it is placed in another individual of the same species, it is termed allograft.
If the graft is placed in another species (e.g., bone from animal to human),
then it is termed xenograft. Among them, autograft is considered the gold
standard and has been used for a long time with good clinical results, but
the supply of autograft is limited. In addition, allograft and xenograft are
not much preferred because of the possibility of pathogen transfer and graft
rejection. Furthermore, tissue/organ procurement is complex, expensive, and
requires additional surgery. As an alternative, attention has been focused on
the use of synthetic material that holds the ability to repair or restore the
functions of a defective system into a normal healthy system upon implantation,
which is termed alloplastic graft. The synthetic material used for this
purpose is called biomaterial. The biomaterial is used either as such or to
manufacture implantable devices or prostheses; some of them are illustrated
in Figure 1.2.
Currently, there are many definitions for the term “biomaterial,” depending
on the user’s own verdict. Biomaterial by definition is a substance or a combination
of substances, other than drugs, derived either from natural or synthetic
origin, which can be used for any period of time as a whole or as a part
of the system that treats, augments, or replaces any tissue, organ, or function
of the body (Williams 1987). Later, Black (1992) defined the term biomaterial
as a material of natural or manmade origin that is used to direct, supplement,
or replace the functions of living tissues of the human body. A biomaterial
is delineated, according to authors’ own description, as any material that
is used for repairing or restoring the functionality of a defective biological
system into a normal healthy system.
The field “biomaterials science and engineering” is a multidisciplinary
theme that essentially coalesces materials science and engineering with
biomedical sciences for the invention of new health-care systems. Since it
is a multidisciplinary field, many experts, in particular materials scientists
and engineers, mechanical engineers, physicists, chemists, biologists, and
clinicians must work together for its continuous development. It has also
witnessed
stable growth over about half a century of existence with the major
contribution from these experts. However, further research and development
is directed at the design and fabrication of novel biomaterials that hold the
features and properties analogous to natural tissues or organs. In the following
section, some imperative successes that have come in the biomaterials
field are provided.
1.2 Biomaterials: From Then to Now
The use of biomaterials to repair human body parts is not new, dating far back
into ancient civilizations. The Egyptians used linen as a suture for wound
closure in around 2000 BC. They also used elephant’s tusks, walrus teeth,
and some kinds of wood to replace bone or missing teeth (Williams and
Cunninghan 1979). Substitution of bone parts in the human body was also
carried
out at that time using copper, but the implant was not successful due
to the effect of copper ion poisoning. As per historical evidence,
the Indians
and the Chinese used waxes, glues, and tissues in reconstructing defective
parts of the human body. It was stated in the Vedic period (1800?1500 BC) of
the ancient Indian literature that artificial legs, eyes, and teeth were used. In
those days, Hindu surgeons performed surgery using autogeneous tissues
for restoring missing parts. Around 600 BC, Sushruta repaired an injured
nose with a patch of living flesh taken from the region of the cheek (Bhat
2002). Around 200 BC, the Greek literature pointed out the use of metals
(e.g., gold). Hippocrates, who is known as the father of medicine, alleged
that metallic wires made of gold might have been used for the treatment of
bone fractures at that time. In the seventeenth century, iron and bronze were
employed in human systems, but they are more corrosive than gold. Some
of the major developments that have occurred in biomaterials are summarized
in Table 1.1 (Park 1984, 2003; Sportnitz 1987; Friedman 1994; Greco 2005;
Murugan 2005a, 2005b).
The first reported clinical application of biomaterials was carried out in
the mid-eighteenth century. In 1759, Hallowell united the edges of a lacerated
brachial artery using a wooden peg and twisted thread (Wesolowski
1963). The use of biomaterials has progressed much since his initial contribution.
By the mid-nineteenth century, Mathijsen introduced a notable
material called lint-reinforced plaster as a bandage in the treatment of bone
fractures. In those days, however, infection was the most common problem
of the materials that were implanted in the human body. Due to the
threat of infection, clinical application of biomaterials was not very successful.
In the 1860s, Lister introduced aseptic techniques, which made some
significant changes in the surgical implant procedures and paved ways
to realize the potential of biomaterials. In 1860, catgut was one of the first
naturally occurring materials used as a suture for wound closure. In 1880,
Gluck used ivory clamps and, in 1989, Jassinowsky used silk on fine curved
needles to repair vessels. In this period, Lane introduced metallic implants
for orthopedics.
The twentieth century was a milestone in the field of biomaterials because
most of the currently used biomaterials and surgical implants were developed
in this period. The practice of using metals and alloys to repair or
replace human body parts was well established at that time. The first metallic
bone plate made of vanadium steel was introduced in 1912 by Sherman,
but it was not very successful because of mechanical failure, corrosion, and
poor biocompatibility. Since this initiation, many metallic implants have been
introduced into the surgical field. Bone plates are surgical tools that are used
to assist in the healing of broken and fractured bones. It is worth pointing
out that bone plates are designed essentially to be very strong and absorb the
large stress forces generated when the bone moves. On the other hand, corrosion
is also a significant concern that typically leads to the disintegration of

生物材料與組織工程前沿進展:從宏觀到微觀的跨學科探索 書籍簡介 本書旨在全麵梳理和深入探討當代生物材料科學與組織工程領域的核心概念、關鍵技術以及未來發展趨勢。本書超越傳統的材料學範疇,重點關注材料與生物係統的復雜交互作用,特彆是從分子尺度到組織尺度的多層次研究方法。我們期望為材料科學傢、生物學傢、工程師以及臨床醫生提供一個跨學科的、具有前瞻性的視角,以理解和設計下一代生物植入物、藥物遞送係統以及再生醫學解決方案。 第一部分:生物材料的本徵特性與設計原則 本部分首先奠定堅實的理論基礎,深入剖析生物材料的結構-性能關係。 第一章:生物材料的分類與基本要求 本章詳細界定瞭生物材料的定義及其在醫療器械、植入物和治療學中的應用譜係。重點闡述瞭材料選擇的關鍵考量因素,包括生物相容性(Biocompatibility)、生物降解性(Biodegradability)和生物活性(Bioactivity)。生物相容性不再被視為簡單的“無毒”標準,而是強調與宿主環境的動態平衡,涉及炎癥反應的調控和免疫原性的最小化。同時,本章深入探討瞭無機材料(如生物活性玻璃、磷酸鈣陶瓷)、有機聚閤物(如聚乳酸、聚己內酯、聚乙二醇)以及復閤材料在不同應用場景下的優勢與局限。 第二章:材料錶麵工程與細胞界麵 材料的宏觀性能固然重要,但細胞層麵的反應往往由材料的錶麵特性決定。本章集中討論瞭材料錶麵處理技術,如等離子體改性、化學接枝和納米圖案化對細胞粘附、增殖和分化的影響。我們詳細分析瞭蛋白質吸附的動力學和熱力學模型,以及如何通過精確調控錶麵潤濕性、電荷和拓撲結構來“指導”細胞行為。特彆是,本章會剖析“錶麵的粗糙度”如何影響特定細胞亞群的命運。 第三章:機械性能與組織匹配 生物材料必須能夠在生理環境下承受特定的機械載荷,並與周圍組織在力學上保持一緻。本章深入研究瞭材料的黏彈性、疲勞強度和蠕變特性。對於骨科和心血管支架材料而言,如何實現力學性能與天然組織的梯度匹配,避免應力遮蔽效應,是設計的核心挑戰。本章將引入先進的有限元分析(FEA)方法,用以模擬材料在體內環境下的長期力學響應。 第二部分:組織工程與再生醫學的核心策略 本部分將視角從材料本身轉嚮材料如何作為支架和載體,驅動組織再生。 第四章:生物活性支架的設計與構建 組織工程支架的核心目標是模仿細胞外基質(ECM)。本章係統地介紹瞭構建三維多孔支架的策略,包括但不限於:相分離法、靜電紡絲(Electrospinning)、3D打印(增材製造)以及水凝膠交聯技術。我們將聚焦於如何控製支架的孔隙率、孔隙連接性以及孔徑分布,以優化營養物質的輸送和代謝廢物的清除。特彆地,對於復雜的組織(如肝髒、腎髒)的再生,支架必須具備多孔結構和多相集成能力。 第五章:生長因子和生物大分子的緩釋係統 單純的支架結構不足以驅動再生,生物活性信號的精確時空遞送至關重要。本章詳細探討瞭生長因子(如BMPs, VEGF)、核酸以及小分子藥物在生物材料中的封裝和釋放機製。內容包括:擴散控製釋放、溶脹/降解控製釋放,以及響應性材料(如pH敏感、溫度敏感水凝膠)的設計。本章將深入分析釋放動力學麯綫的數學建模,確保信號能夠在組織修復的關鍵窗口期內持續或脈衝性地被激活。 第六章:細胞-材料相互作用的分子機製 理解細胞如何“感知”其所處的支架環境是組織工程成功的關鍵。本章關注整閤素介導的信號傳導通路,以及細胞骨架的重塑如何響應支架的力學和化學信號。我們將討論細胞黏著斑點(Focal Adhesions)的形成與動力學,以及這些分子事件如何最終決定細胞的命運——是增殖、分化還是凋亡。對於乾細胞(如間充質乾細胞,iPSCs)的定嚮分化,材料環境的“教導”作用是本章的核心討論點。 第三部分:先進製造技術與臨床轉化 本部分聚焦於如何將實驗室成果轉化為可規模化生産和臨床應用的生物産品。 第七章:增材製造(3D/4D打印)在生物材料中的應用 增材製造技術,特彆是生物打印(Bioprinting),正在徹底改變植入物和組織模型的製造範式。本章詳細介紹瞭幾種主流的生物打印技術(如擠齣式、噴墨式、光聚閤式),並討論瞭生物墨水(Bioink)的配方挑戰——如何在保證可打印性的同時維持細胞活力和生物活性。此外,4D生物打印的概念,即材料在打印後能隨時間或環境變化而改變形狀或功能,是本章的前沿探討內容。 第八章:體內診斷與智能植入物 未來的生物材料將不再是被動植入物,而是能夠與宿主進行信息交互的智能係統。本章介紹瞭集成傳感器的生物材料,用於實時監測植入部位的pH值、氧分壓或炎癥標誌物。同時,我們探討瞭可植入設備(Implantable Devices)的生物相容性封裝技術,以及如何確保這些電子元件在潮濕且具有腐蝕性的體內環境中長期穩定工作。 第九章:臨床轉化中的法規與挑戰 從實驗室到病床,生物材料麵臨著嚴格的監管審查。本章概述瞭FDA和EMA對生物植入物和再生醫學産品的審批流程,重點討論瞭長期毒理學測試、免疫原性風險評估以及生物降解産物的體內代謝途徑研究。實現可重復、可控的製造流程(GMP標準)以及解決大規模生産成本是本章討論的實踐性難題。 本書力求在理論深度和應用廣度之間取得平衡,為讀者提供一個全麵而富有洞察力的生物材料與組織工程領域導覽。
