Chia-Wei Jui, Amy J C Trappey, Chien-Chung Fu
Nanotechnology, like 3D printing, is one of the richest fields in research and progress in the past few years. Two Photon Polymerization (TPP) technology allows the 3D printing of nanoscale objects, so the nanoscale additive manufacturing has been no longer the thing in the future. This research investigates related US patent documents through the claim-based approach. By virtue of systematic analysis of the claims of patent documents, we can explicitly define technical features of patent document and the accurate patent classification, monitor the direction of enterprises' patent application portfolio and effectively grasp the trend of technological development of important manufacturers related to this technology...

Chia-Wei Jui, Amy J C Trappey, Chien-Chung Fu
Nanostructure is necessary for the existing industrial application, future development of technology or manufacturing of advanced products. Regarding the requirements of industrial technology on large area and pattern refinement, the bottleneck of lithography technique is also the key to development. The mask-less laser interference lithography can produce large area exposure and define periodic nanoscale surface pattern in the spatially periodic manner to effectively lower the cost. This research investigates related US patent documents and the findings of patent review in this research show the structure architecture of this technique has different forms, and the beam splitter architecture has advantages and application potentials on the extensive requirements of complex periodic structure...

Guillermo Foladori, Eduardo Robles-Belmont, Edgar Ramon Arteaga-Figueroa, Richard Appelbaum, Edgar Zayago-Lau
This paper examines nanotechnology patents in Mexico. First, we identify nanotechnology patents and their growth between 1993 and 2014; considering those patents in nanotechnology where at least one assignee has a Mexican address. Second, we applied a methodology to allocate each patent to the most likely potential economic sector of application. The procedure can be replicated for other countries. The main conclusion is that although there is a significant registration of patents in nanotechnology in Mexico, most of them are oriented towards basic research and came out of public research centers, which raises doubts about the connection to the private sector and a short term application in commercial goods...

Javier Maira, Javier Etxabe, Pedro A Serena
Nanoscience and nanotechnology made their appearance in the scientific scene at a time when both the economy of Spain and the Spanish Research and Innovation System were experiencing strong growth. This circumstance resulted in a remarkable development of nanoscience and nanotechnology especially in universities and public research institutions such as the Spanish National Research Council (Consejo Superior de Investigaciones CientĂ­ficas-CSIC). However, this development in academia has not been reflected in a similar increment in the transfer of knowledge to the productive sector despite several efforts and initiatives were launched...

Nidhi Saiwal, Mandeep Dahiya, Harish Dureja
BACKGROUND: Ultrasound (US) has the ever-rising role in the delivery of therapeutic agents that includes chemotherapeutic agents, proteins, and genetic material. The microbubbles are the cavitating gas bodies that act as the mediators through which the energy of relatively non-interactive pressure waves is accumulated to produce forces that can permeabilize cell membranes and disrupt the vesicles that carry the therapeutic agent. This shows that the microbubbles greatly enhance the delivery of smaller chemical agents, proteins and genetic material...
