Nanomaterials had attracted much attention since their discovery with their unique structure, peculiar physical,
chemical, mechanical properties and potential application prospects. In the past few years, the theoretical and
experimental research on biological nanomaterials has become the focus of attention, especially the biochemistry,
biophysics, biomechanics, thermodynamics and electromagnetism of nucleic acid and protein, while its intelligent
composites have become the forefront of life science and materials science. At present, nano-bio-chip materials,
biomimetic materials, nano-motors, nanocomposites, interface biomaterials, nano-sensors and drug delivery systems
have made great progress. In this paper, the characteristics of these materials, research and development of the
application were reviewed, a brief overview of the nano-materials in the life sciences of the main applications, and to
explore the development prospects of biological nano-materials.

Because the current social water pollution is serious, and the conventional method cannot eff ectively manage all
types of water pollution, and its single eff ect cannot be satisfactory, we must seek new and eff ective treatment. The
paper is a comprehensive review of the best practices of the conventional wastewater treatment method with reference
to the experiments and research results of nanotechnology in sewage treatment. Comparison of nanotechnology can
be compared with conventional methods to make the particles have a special function, and some special performance
just in the sewage treatment medium to a good effect: the depth of the catalytic method can be effective in the
decomposition of many types of organic pollutants such as halogenated hydrocarbons Class, chlorinated phenols,
cyanide, various organic acids and can handle metal particles; adsorption method for the water heavy metal pollution
treatment costs less, simple and widely used, nanofi ltration membrane can replace the adsorption and electrochemical
methods, Pulping and precipitation are one of the most eff ective methods for the treatment of colloidal wastewater. It
can eff ectively reduce the turbidity and chroma of waste water, remove a variety of macromolecular organic matter and
some heavy metal ions ( Mercury and lead); organic / inorganic composite nanoparticles with its excellent inorganic
materials, light, electricity, magnetic and other properties, organic materials, excellent processing performance,
biocompatibility, for many diffi cult to deal with water pollution control, which has a corresponding method, can be
simple and eff ective to solve the problem. The application of nanotechnology in water treatment has shown a broad
prospect, but needs further research and improvement.

The research of semiconductor nanomaterials is the forefront of contemporary science and technology. Because of
its optical nonlinearity and luminescent properties diff erent from the bulk materials, it has great application prospect
in the future optical switch, optical storage, light fast conversion and ultra-high speed processing. By arranging the
commonly used low-dimensional semiconductor nanomaterials preparation methods and methods of characterization,
then compare them, it can helps to open up ideas and aids for in-depth thinking. In this paper, the preparation methods
of laser ablation, carbon nanotube template, molten salt, solution-liquid-solid method and template electrochemical
method are introduced. The characterization method is analyzed from particle size and morphology, composition and
structure analysis, surface interface analysis and several other aspects.

In this paper, the cage nanoporous silica is composed of ethyl orthosilicate as silicon source, triblock copolymer
poly (ethylene oxide) -poly (propylene oxide) -polyethylene oxide (F127) as structure guide agent and additive, while
the Fm3m cubic structure of cage type nanoporous silica was prepared by hydrothermal synthesis method. It is easy
to control the self-assembly of the silica triblock copolymer intermediates thermally. In addition, the change in sample
pore size and pore volume can be achieved by a hydrothermal reaction at a temperature of 100 ° C to 150 °C. Small
angle X-ray diff raction shows that these samples have ordered pores, while adsorption studies show that they have
high porosity, uniform distribution of bimodal pores and large pore volume. Use separation of p-methylbenzene borate,
iodobenzene and biphenyl by using three kinds of cage-type nanoporous silica materials as chromatographic fi llers. The
results showed that the material prepared at 130 ℃ under hydrothermal condition had the best eff ect on the separation
of three organic compounds.
