나노물질이 갖는 특유의 성질을 질병의 진단, 치료
nanoparticles that can carry the drug molecules to the target safely.
5.2.2 Nanocarriers - Nanoparticles
Before starting with the functionalization of nanoparticles, it is important to keep in mind a range of useful properties we wish to have in any drug delivery across the BBB(Blood brain barrier). In this context, owing to their small size, customizable surface, improved solubility, tar
Characteristic of MOGS
1. Metal oxides possess electronic, chemical, and physical properties of high sensitivity to changes in their chemical environment.
2. The sensing properties of semiconductor metal oxide assures improved selectivity and stability
3. Their peculiar characteristics and size effects make them interesting for metal oxide gas sensors
The reason we take Nox as targe
The cathode electrocatalyst was the electrostatic adduct of bilirubin oxidase (BOD) also a polyanion at physiological pH
Carbon Nanotube-AttachedGlucose Oxidase for Biofuel Cells
The carbon electrode coated with CNT–GOx composites
was applied as an anode in a model glucose/O2 biofuel cell
CNT-supported glucose oxidase (CNT–GOx) was examined in the presence of 1,4
fibers.
Properties
heat-resistance, low electrical conductivity, flexibility, and high tensile strength were essential factors
The toxic properties of such fibres are dependent upon a diameter narrow enough to allow inhalation deep into the lung, a length that prevents their removal by macrophages, resistance to dissolution in tissue fluid, and a surface able to cause oxidative damage.
of oxidative phosphorylation. So H+ pumps transport protons to extracellular fluid to maintain normal cytoplasmic pH.
Thus, Tumor acidity is a specific tumor biomarker. pHLIP is pH-dependent molecule, so it detects the concentration change of proton. If pH is lower in extracellular surface, this molecule enters into phospholipid bilayer due to transmembrane part containing uncharged Asp by

I. INTRODUCTION
Single nucleotide polymorphisms (SNPs) comprise the most abundant source of genetic variation in the human genome. A SNP is a DNA sequence variation occurring when a single nucleotide — A, T, C or G — in the genome (or other shared sequence) differs between member
coated ZnO nanowires, suggesting that the core ZnO nanowires, including the nanoparticle-comprising tips[13], have been coated with the AZO layer.
