    To examine nanoparticle toxicity there is a need to produce defined nanoparticles dispersed in a colloidal suspension. Such a solution could also be interesting for other fields such as nano-medicine. In order to disperse the particles in the liquid there are often surfactant added to the process that alternates the surface of the particles. As the research shows that the surface of a nanoparticle can play a large role of its effects in biological systems, the relevance of these methods have been questioned. By depositing the airborne particles directly in a liquid this mentioned primary treatment can be avoided. A new method for depositing on liquid has been developed that appears to avoid the formation of a film consisting of stagnant nanoparticle-protein complexes. Particles deposited on a recirculating liquid by the means of electrostatic forces, the method is realized in a device-named Aeroid. The methodology also allow larger volumes of fluid with suitable concentration. Also the size of nanoparticles can be produced which, from an application perspective, is desirable. Design, loss measurements and efficiency measurements were included in the method development for the Aeroid. Analyses in the form of materials, volume of the liquid and on how the particles are expected to move in the electric field was performed. For deposition in the Aeroid an aerosol of spherical goldnanoparticles was employed, with size about 60 nm, produced by means of a spark generator in series with a high-temperature-oven. The aerosol is then passed through a bipolar charger to obtain a well known charge distribution, Boltzmann-Fuch. To determine which type of protein solution that could be used to produce a colloid solution with 60 nm gold particles in the Aeroid a control measurements in an ESP where made. There was two types of proteins IgG and BSA added into water, PBS and TRISS. The deposit was made with the same length of time and with the same aerosol concentration for all control measurements. The reddest membrane i. e. the highest concentration of gold nanoparticle-protein complex was found when the BSA was dissolved in PBS. This solution was used for depostion in the Aeroid. When the voltage with a field strength of 1.2 kV/cm, was turned on in the Aeroid 17 % of the produced particles where deposited. It resutled in losses between 13 and 37% at 60 nm, most likely due to diffusion. Efficiency measurements were carried out partly in a SMPS by comparing the penetration of particles in the Aeroid when high voltage was on/off. A complement to the deposition measurement PIXE analysis to determine the concentration of gold in the liquid. Analysis by spectrophotometry and visual inspection shows that generation of a 65 ml solution of dispersed gold nanoparticles was successfull. Future research and development should put emphasis on the analysis of the proportion of the particles which are dispersed in order to evaluate whether the Aeroid may be used for the production of other types of particle-protein solution combinations.För att undersöka nanopartiklars toxicitet finns behov av att producera vĂ€ldefinierade nanopartiklar dispergerade i en kolloid suspension. Men Ă€ven för andra omrĂ„den sĂ„ som nanomedicin finns ett behov av denna typ av lösningar. För att dispergera partiklarna i vĂ€tska anvĂ€nds ofta ytaktiva Ă€mnen. NĂ€r dessa Ă€mnen tillsĂ€tts adderas de pĂ„ ytan av partikeln och förĂ€ndrar partiklarnas yta. DĂ„ forskning visar att ytan pĂ„ en nanopartikel kan spela stor roll för dess effekt i biologiska system har dessa metoders relevans ifrĂ„gasatts. Genom deponering av luftburna nanopartiklar direkt pĂ„ vĂ€tska, kan tillsatsen av ytaktiva Ă€mnen undvikas. En ny metod, som innebĂ€r deponering pĂ„ vĂ€tska har utvecklats som syftar till att undvika bildandet av en hinna bestĂ„ende av ansamlade nanopartikel–protein komplex. Partiklar deponeras hĂ€r pĂ„ en recirkulerande vĂ€tska med hjĂ€lp av elektrostatiska krafter och metoden realiseras i en anordning med arbetsnamnet Aeroid. Metodiken tillĂ„ter Ă€ven att större vĂ€tskevolymer med önskvĂ€rd koncentration och storlek av nanopartiklar kan produceras vilket ur ett tillĂ€mpningsperspektiv Ă€r efterstrĂ€vansvĂ€rt. Design av Aeroiden, förlustmĂ€tningar av aerosolen och effektivitetsmĂ€tningar med avseende pĂ„ deponering av aerosolen i Aeroiden ingick i metodutvecklingen. Analyser i form av materialval, storlek pĂ„ vĂ€tskevolym samt berĂ€kningar pĂ„ hur partiklarna förvĂ€ntas röra sig i det elektriska fĂ€ltet genomfördes. För att bestĂ€mma vilken typ av proteinlösning som skulle anvĂ€ndas för att producera en kolloid lösning med 60 nm guldpartiklar i Aeroiden gjordes referensexperiment, var vid olika proteiner testades vatten och tvĂ„ andra buffertsystem. Den högsta koncentrationen av guldnanopartikel-protein komplex, dvs dĂ„ vĂ€tskehinnan blev somrödast, Ă„terfanns dĂ„ ett blodprotein, albumin, var löst i fosfatbuffert. Denna lösning anvĂ€ndes sedan vid de fortsatta testerna av Aeroiden. DĂ„ spĂ€nningen var pĂ„slagen i Aeroiden deponerades ca 17 % av partiklarna. De största förlusterna skedde pĂ„ grund av partiklarnas diffusion, men vissa förluster kunde Ă€ven observeras pĂ„ grund av statisk elektricitet. Som ett komplement till effektivitetsmĂ€tnigarna bestĂ€mdes koncentrationen av guld i vĂ€tskan med hjĂ€lp av PIXE. Analys med spektrometri samt visuell inspektion visar att Aeroiden kan framstĂ€lla 65 ml albuminlösning med dispergerade guldnanopartiklar. Framtida forskning och utveckling borde lĂ€gga stor vikt vid analys av hur stor del av partiklarna som Ă€r dispergerade för att kunna utvĂ€rdera huruvida Aeroiden kan anvĂ€ndas för produktion av andra typer av partikel-proteinlösningskombinationer. Snabblexikon:. Pixe: stĂ„r för proton induced x-ray emission. Protoner bombarderas pĂ„ ett filter med substratet, detta leder till att elektromagnetisk strĂ„lning specifik för vart Ă€mne skapas. Denna strĂ„lning fĂ„ngas upp och ger svar pĂ„ vilka Ă€mnen samt hur mycket av dessa Ă€mnen som finns i substratet

    Value Creation in Innovation Ecosystems: How the Structure of Technological Interdependence Affects Firm Performance in New Technology Generations

    Get PDF
    The success of an innovating firm often depends on the efforts of other innovators in its environment. How do the challenges faced by external innovators affect the focal firm\u27s outcomes? To address this question we first characterize the external environment according to the structure of interdependence. We follow the flow of inputs and outputs in the ecosystem to distinguish between upstream components that are bundled by the focal firm, and downstream complements that are bundled by the firm\u27s customers. We hypothesize that the effects of external innovation challenges depend not only on their magnitude, but also on their location in the ecosystem relative to the focal firm. We identify a key asymmetry that results from the location of challenges relative to a focal firm—greater upstream innovation challenges in components enhance the benefits that accrue to technology leaders, while greater downstream innovation challenges in complements erode these benefits. We further propose that the effectiveness of vertical integration as a strategy to manage ecosystem interdependence increases over the course of the technology life cycle. We explore these arguments in the context of the global semiconductor lithography equipment industry from its emergence in 1962 to 2005 across nine distinct technology generations. We find strong empirical support for our framework

    Innovation Ecosystems and the Pace of Substitution: Re-Examining Technology S-Curves

    Get PDF
    Why do some new technologies emerge and quickly supplant incumbent technologies while others take years or decades to take off? We explore this question by presenting a framework that considers both the focal competing technologies as well as the ecosystems in which they are embedded. Within our framework, each episode of technology transition is characterized by the ecosystem emergence challenge that confronts the new technology and the ecosystem extension opportunity that is available to the old technology. We identify four qualitatively distinct regimes with clear predictions for the pace of substitution. Evidence from 10 episodes of technology transitions in the semiconductor lithography equipment industry from 1972 to 2009 offers strong support for our framework. We discuss the implication of our approach for firm strategy
