Recent Patents on Creative Ionizing Radiation in Nanotechnology

Abstract

Nanotechnology is one of the fastest developing new areas in science and technology. Ionizing radiation is widely applied for nanostructure synthesis and nanomaterials modification. The ability to fabricate structures with nanometric precision is of fundamental importance to any exploitation of nanotechnology. Nanofabrication involves various lithographies to write extremely small structures. An interesting field of radiation nanotechnological application concerns the development of nano-ordered hydrogels for biosensors. New trends and more precise treatment technology were applied: surface curing and modification, polymer functionalization are good examples of such developments. Patents on application of ionizing radiation in nanotechnology focused on many different approaches to this topic, not only nanoparticles synthesis but also nanostructure modification or functionalization.

Ionizing radiation: a versatile tool for nanostructuring of polymers

“…Ionizing and penetration ability of high energy radiations will benefit easy and rapid preparation of nanomaterials such as nanogels, nanocomposites, nanoparticles for a variety of applications ranging from drug delivey to tissue engineering, from sensors/detectors to specialty membranes. The increasing role of ionizing radiation in nanotechnology applications has been emphasized in a compilation of patents based on the use of radiation in nanotechnology [64]. The prospect of using ionizing radiation in nanotechnology is not limited to the applications mentioned in this review but will diversify to include the preparation of monoliths [65] for chromatographic applications, controlling of cavity size in molecularly imprinted polymer matrices [66], etc.…”

A doped-polymer based porous silicon photonic crystal sensor for the detection of gamma-ray radiation

“…1,2 Ionizing radiation has recently become more widely used for a variety of applications. 3,4 Industrial radiation processing and control, cancer cell treatment, medical sterilization, food preservation, and environmental gamma dosimetry are demonstrated among the applications where radiation dosimeters are used. 3,5–7…”

“… 8 There are different types of radiation dosimetry used to detect ionizing radiations. 4 A scintillation dosimeter is one of the oldest types of dosimeters, which uses the scintillation light produced in particular materials. Scintillation dosimeters work on the principle that the substance being utilized can convert ionizing radiation into detectable light.…”

Influence of Synthesis Method on Structural, Morphological, Magnetic, and Antimicrobial Properties of Fe-Ag Nanoparticles

“…To palliate such drawbacks, interest has been focused on the development of one-pot, less harmful, facile, cheap, reliable, and eco-friendly synthesis protocols by using nontoxic solvents and reagents under mild conditions. The aim is to largely produce the desired NPs whereby the size, shape, and morphology can be controlled, with supplementary attributes such as the inhibition of spoilage microorganisms for human health concerns [23][24][25]. Notably, for such synthesis, high-energy gamma Co 60 ray irradiation is considered as an effective method for the synthesis and modification of nanomaterials due to several benefits such as (1) the reduction of metal ions to zero-valent metal particles under ambient conditions with minimized use of reducing agents; (2) the ability to control the rate of reduction reaction; (3) large-scale production potential that can be favorably set up with satisfactory requirements of a clean production process [26,27].…”
