Potential of Porous Silicon Doped With Gold Nanoparticles in Detection of Biogenic Amine. Porous Silicon Used in the Detect

 

Authored by Francisco Severiano Carrillo

Due to its properties porous silicon is a material with high potential to be applied in bio-delivery carriers and biosensors. To enhancement the capacity of porous silicon as biosensor, gold nanoparticles are introduced in its structure. One of the most used methods to obtain porous silicon/Au nanoparticles is metal salt-assisted chemical etching. The high surface of porous silicon matrix and the Au nanoparticles allow the increment of the sensitivity of the biosensor. This structure can be use as platform to got a biogenic amine optic biosensors. This kind of sensors (optic) are based on the changes of the signals related to the reactions between biogenic amines and the recognized element used (diamine oxidase).

  Global Journal of Nanomedicine-Juniper publishers Introduction Nanotechnology is the capability to examine, see and manipulate the things on atomic or molecular scale usually under 100nm. At this scale many effects are arises such as large surface to volume ratio, minimizing effects of gravity, quantum effects etc. Metal nanoparticles have fascinated researchers due to their impending applications in various fields like biomedical applications and sensitive diagnostic assays, radiotherapy enhancement, and thermal ablation, gene delivery, as non toxic carriers for gene and drug-delivery applications, optical imaging and labelling of biological systems [ 1 - 3 ]. These tiny particles are known as nanoparticles, which are synthesized by generally two methods top down and bottom up ( Figure 1 ). The top down suggest the nanoparticles preparation by lithographic techniques, ball milling, etching, sputtering, etc. The most effective approach for synthesi...

Synthesis of Magnetic Oxide Nanoparticles for Biomedical Applications-Juniper publishers

Image
  Global Journal of Nanomedicine-Juniper publishers Introduction Magnetic oxide nanomaterials, including iron oxide (Fe 3 O 4 and γ-Fe 2 O 3 ), spinel ferrites (MFe 2 O 4 ; M=Mn, Zn, Cr, Ni, or Co) and hexagonal ferrite (MFe12O19, M=Ba and Sr) are attracting much attention due to their wide application potentials in advanced magnets, electronic devices, information storage, magnetic resonance imaging (MRI), and drug-delivery technology [ 1 - 6 ]. Hence, the synthesis and applications of nano structured magnetic ferrite has become a particularly important research field. In this mini-review, we will first focus on the recent research progress of the synthesis of magnetic oxide nanoparticles. Afterwards, the biomedical applications, particularly the hyperthermia, drug delivery and contrast agents in magnetic resonance imaging (MRI), will be reviewed. Synthesis of magnetic oxide nanoparticles In the last decades, tons of efforts have been devoted to the...

Microwave Induced Green synthesis of nanostructured ZnO as Promising Antibacterial Agent-Juniper publishers

Image
  Global Journal of Nanomedicine-Juniper publishers Introduction Antibacterial materials typically constitute chemical compounds that locally kill bacteria or effectively slow down their growth, with no toxic effects on the surrounding tissues. While organic antimicrobial agents act relatively quicker than inorganic antibacterials, their extensive usage develops drug resistance in more and more bacteria [ 1 - 3 ]. In order to address this issue, inorganic metal oxides such as TiO 2 , MgO, CuO, Al 2 O 3 , Ag 2 O, CaO, CeO 2 and Zno have come forward which can act as durable antibacterial agents and provide appropriate disinfection without forming harmful by-products thereby offering key advantages of improved safety and stability as compared to organic antibiotics [ 2 - 5 ]. Zinc oxide is a non-toxic, n-type II-VI semiconductor material having a wurtzite structure with a direct and wide band gap of 3.37 eV. It exhibits near- UV emission, optical transparency, elec...
