Subject Keyword: 020500 Optical Physics
Language: eng
Resource Type: conference paper
Identifier: http://hdl.handle.net/1959.14/285284
Description: Nanoparticles are rapidly becoming ubiquitous in modern technology and so there is an emerging need to characterise single nanoparticles rapidly and accurately. In the current technological paradigm, ... More
