RASHID AMIN,SIEUN HWANG,박성하 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2011 NANO Vol.6 No.2

Nanotechnology is one of the most important emerging fields of science in this century. It deals with designing, construction, investigation, and utilization of systems at the nanoscale. Another interesting research discipline of current day is biotechnology, which gives us a way to understand biological system and to utilize our knowledge for industrial manufacturing. Nanobiotechnology lies at the interface of these two research fields. It exploits nanotechnology and biotechnology to analyze and create nanobiosystems to meet a wide variety of challenges and develops a wide range of applications.

Biological green synthesis of gold and silver nanoparticles

Sur, Ujjal Kumar Techno-Press 2014 Advances in nano research Vol.2 No.3

Nanomaterials synthesized by natural bioresources such as microorganisms, animals and plants in nature can also be synthesized in laboratories even on large scale. This is considered as an attractive prospect for eco-friendly or so-called green synthesis. Development of eco-friendly synthesis of biocompatible nanoparticles and their potential biomedical applications introduces the concept of nanobiotechnology. The lower cost and lesser side effects as compare to chemical methods of synthesis are the main advantages of biosynthesis. This review article demonstrates the role of various biological resources e.g. bacteria, fungi, actinomycetes, plant leaves, fruits and honey as well as animal tissues for the synthesis of nanoparticles mainly gold and silver with an overview of their potential applications.

Green synthesis of fluorescent carbon nanoparticles from Lychee (Litchi chinensis) plant

Vidhi Chaudhary,Anil Kumar Bhowmick 한국화학공학회 2015 Korean Journal of Chemical Engineering Vol.32 No.8

Fluorescent carbon nanoparticles (CNPs) were prepared from waste lychee peel by hydrothermal process using green chemistry. These CNPs were characterized by UV-vis absorption, fluorescence spectroscopy, Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction. Their morphology was analyzed by field emission scanning electron microscopy. Spherical carbon nanoparticles with a particle size ranging from 40-70 nm were observed. FTIR data indicated that these CNPs were functionalized with hydroxyl and carboxylic or carbonyl group. The maximum fluorescence intensity for these CNPs was observed on the excitation wavelength at 365 nm with emission maxima centered at 450 nm. These particles exhibited excitation wavelength dependent fluorescence emission spectra. CNPs were found to be highly fluorescent and exhibited high water solubility. The band gap was estimated to be 3.8 eV. Therefore, as prepared CNPs would be useful in bioimaging, biolabeling and in the other applications of nanobiotechnology.

Designer nanoparticle: nanobiotechnology tool for cell biology

Thimiri Govinda Raj Deepak B.,Khan Niamat Ali 나노기술연구협의회 2016 Nano Convergence Vol.3 No.22

This article discusses the use of nanotechnology for subcellular compartment isolation and its application towards subcellular omics. This technology review significantly contributes to our understanding on use of nanotechnology for subcellular systems biology. Here we elaborate nanobiotechnology approach of using superparamagnetic nanoparticles (SPMNPs) optimized with different surface coatings for subcellular organelle isolation. Using pulse-chase approach, we review that SPMNPs interacted differently with the cell depending on its surface functionalization. The article focuses on the use of functionalized-SPMNPs as a nanobiotechnology tool to isolate high quality (both purity and yield) plasma membranes and endosomes or lysosomes. Such nanobiotechnology tool can be applied in generating subcellular compartment inventories. As a future perspective, this strategy could be applied in areas such as immunology, cancer and stem cell research.

ADVANCES IN F0F1-ATP SYNTHASE BIOLOGICAL PROTEIN NANOMOTOR: FROM MECHANISMS AND STRATEGIES TO POTENTIAL APPLICATIONS

A. R. KHATAEE,H. R. KHATAEE 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2009 NANO Vol.4 No.2

Movement and shape changes are fundamental aspects of all living organisms. This biological motility results from the biological nanomotors, in particular protein nanomotors. Cells contain a variety of protein nanomotors that rotate (e.g., F0F1-ATP synthase or bacterial flagellar motors) or move in a linear fashion (e.g., the kinesin, myosin and dynein motors). F0F1-ATP synthase is one of the ideal nanomotors or energy providing systems for micro/nanomachines because of its small size, smart and perfect structure, and ultra-high energy transfer efficiency. Therefore, in this paper, we have reviewed the structure, mechanism, and potential applications of the F0F1-ATP synthase nanomotor. In all organisms, the F0F1-ATP synthase consists of two distinct nanomotors, F0 and F1. The F0 moiety is embedded in the membrane and is a detergent soluble unit while the F1 moiety protrudes from the membrane and is a water soluble unit. F0F1-ATP synthase operates as two stepper motor/generators coupled by a common shaft and an electrochemical-to-mechanical-to-chemical energy transducer with an astounding 360° rotary motion of subunits. F0F1-ATP synthase nanomotor may enable the creation of a new class of sensors, mechanical force transducers, actuators, and nanomechanical devices. Thus, the F0F1-ATP synthase nanomotor field has expanded into a wide variety of science.

Multiscale Biofluidic and Nanobiotechnology Approaches for Treating Sepsis in Extracorporeal Circuits

강주헌 한국바이오칩학회 2020 BioChip Journal Vol.14 No.1

Infectious diseases and their pandemics periodically attract public interests due to difficulty in treating the patients and the consequent high mortality. Sepsis caused by an imbalanced systemic inflammatory response to infection often leads to organ failure and death. The current therapeutic intervention mainly includes “the sepsis bundles,” antibiotics (antibacterial, antiviral, and antifungal), intravenous fluids for resuscitation, and surgery, which have significantly improved the clinical outcomes in past decades; however, the patients with fulminant sepsis are still in desperate need of alternative therapeutic approaches. One of the potential supportive therapies, extracorporeal blood treatment, has emerged and been developed for improving the current therapeutic efficacy. Here, I overview how the treatment of infectious diseases has been assisted with the extracorporeal adjuvant therapy and the potential utility of various nanobiotechnology and microfluidic approaches for developing new auxiliary therapeutic methods.

When innovation occurs with the collaboration among different technological/ industrial fields, it is called technology fusion. This phenomena influences broader areas and leads to the development of technologies. Technology fusion appears more frequently in knowledge-intensive fields. Despite its attractiveness, there is limited research in technology fusion due to insufficient data in this field. In this paper, we, utilizing nanobiotechnology, suggest six patent indexes that measure the degree of technological development to analyze the characteristics of fusion technology. By using backward and forward citation information of US patent, we obtain degree of technological diffusion and fusion, technology impact, technology potential, technology cumulativeness, and technology potential. The fields of USPC 435(molecular biology and microbiology), 436(analytical and immunological testing), and 424(drug, bio-affecting and body treating composition) that show the high level of patent activities and technology potential also exhibit the high value of technological diffusion index. This suggests that these technology fields have higher diffusion effects into diverse fields of technologies as well. The values of technology fusion index for 528(synthetic resins or natural rubbers), 600(surgery), and 436(analytical and immunological testing) are high, which implies that these technology fields are developed with diverse fields of technologies. These outcomes can help us to predict the technological trend, new technology opportunities, and the source technologies of nanobiotechnology as well as serve as a basis for technology roadmapping.
