In this work we tried to develop a smart PLA film, especially to improve its potential food applications providing antibacterial properties by means of functionalization of the film surface with cardanol-based vesicle nanodispersion obtained by an environmental-friendly process. We used cardanol-based nanovesicles loaded with porphyrin molecules itself cardanol functionalized, in order to prepare a composite material that can act as potential “smart film” as acid indicator: the film changes its colour according to the acid atmosphere it reveals thanks to the conformational change of porphyrin. Starting from commercial PLA pellets, films were extruded and cardanol-based nanovescicles embedded with porphyrin were deposited on these PLA films by simple casting of the aqueous vescicular nanodispersion. The functionalized PLA films were then studied by mechanical testing. SEM-FEG characterization, and UV -visible measurements were performed to investigate the presence of cardanol-based nanodispersion on the film and the acid response of porphyrin.","PeriodicalId":413629,"journal":{"name":"2015 1st Workshop on Nanotechnology in Instrumentation and Measurement (NANOFIM)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133067561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently a plethora of novel nanomaterials were developed as contrast agents and/or drug delivery systems. In this work, we report the use of micro-bubbles and gold nanorods (GNRs) as vascular contrast agents for the characterization of tumor micro-environment, combining HF-US and PA imaging. A bolus of 50µL of untargeted micro-bubbles and a bolus of 150µL of GNRs solution were injected intravenously in two male colon cancer xenograft mice and detected with a commercial PA-US imaging system. The subcutaneous tumor dimensions were assessed by means of B-mode images (146.48 mm2and 24.56 mm2); different perfusion parameters were estimated tracking the micro-bubbles (peak enhancement map; time to peak 51,3s, 58,7s and 39s and wash-in rate 35,5s, 5,4s and 109,4s for different tumor regions); the real time distribution of GNRs in the tumor was assessed by means of the amplitude variation of the PA signal during time (30 % increase of the PA signal 28 min after injection). The combination of HF-US and PA imaging could become an efficient and non invasive tool for the in vivo and real-time evaluation of the tissue viability, to visualize the map of perfusion and monitoring the efficacy of drug/nano-particle delivery. The use of targeted microbubbles and nanoparticles could open new avenues for the real-time mapping of specific cell epitopes and phenotypes.","PeriodicalId":413629,"journal":{"name":"2015 1st Workshop on Nanotechnology in Instrumentation and Measurement (NANOFIM)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124630627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various HNT concentrations (range 0.25-3.00 mg/mL) were dispersed in custom-designed tissue-mimicking phantoms and exposed to different ultrasound frequencies (7–11 MHz) through a conventional clinically-available echographic device. Off-line analysis included the evaluation of both amplitude of backscattered ultrasound signals and image brightness. Amplitude of HNT-backscattered signals showed a linear increase with particle concentration, while image brightness enhancement was limited by logarithmic compression effects. On the other hand, backscatter amplitude showed significant increments with increasing ultrasound frequency up to 10 MHz, then showing a concentration-dependent behavior without further enhancements. Overall, the most effective response was found when a 10-MHz ultrasound frequency was employed to insonify HNTs at a concentration of 1.5 mg/mL. In conclusion, the present study optimized the combination of incident ultrasound frequency and HNT concentration, in order to obtain an echographic image enhancement suitable for medical applications. Future dedicated studies will assess the feasibility of automatic detection of HNTs within echographic images and their possible employment as theranostic agents.","PeriodicalId":413629,"journal":{"name":"2015 1st Workshop on Nanotechnology in Instrumentation and Measurement (NANOFIM)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128260507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
