“…Despite their merits in integration and automation, only very few microfluidic reaction systems have utilized the inline analysis for materials synthesis, [126][127][128][129] even fewer cases for silica materials with no traceable optical, electronic, fluorescent, and magnetic properties. However, it is expected that, with the development of new miniaturized technological systems, more dedicated analysis tools can be integrated into microfluidic flow reactors for greatly increasing the depth of information available during the formation of silica particles.…”

“…In order to synthesize a narrow size distribution of the CdSe QDs, a microreactor system was employed as has been used in previous reports. 20 Cd(CH 3 COO) 2 ·H 2 O was dissolved in a solution of oleic acid and octadecene (ODE) at 180 • C under a flow of argon. A solution of Se powder dissolved in trioctylphosphine (TOP) was separately prepared.…”

“…The CdSe/ZnS core/shell QDs were later synthesized using hot-injection methods. [20][21][22][23][24] To exchange the surface capping agent of the QDs for the amine passivation, APOL and H 2 O (v/v 10/1) solutions were loaded into the TOP capped QDs solution. The solution was then stirred intensively by a magnetic stirrer and simultaneously irradiated several times using a halogen lamp.…”

“…A integração online aos sistemas microfluídicos de técnicas de análise química instrumental cromatográfica (MA et al, 2009), eletroquímica (LIN et al, 2015 e espectroscópica (WANG, N. et al, 2016) permite o controle direto do processo sintético, possibilitando a automatização e otimização da reação (KRISHNAN et al, 2001;WAGNER e KÖHLER, 2005;DITTRICH e MANZ, 2006;HARTMAN e JENSEN, 2009;YUE et al, 2012;COUTO et al, 2015;MACEICZYK et al, 2015) As vantagens da TMR integrada às técnicas de monitoramento em tempo real permitem o controle preciso das condições do processo, com uma taxa de fluxo bem definida, mistura eficiente, distribuição de temperatura uniforme e operação segura em uma ampla janela de processo. Além disso, torna-se um meio atraente para a extração de informações cinéticas e rápida aquisição de dados (TAKAHASHI et al, 2007;SWAIN et al, 2017).…”

“…Para tal, a reação deve ser controlada para assegurar que a nucleação tenha um período tão curto quanto possível e não mais ocorra agregação e coagulação de partículas individuais durante o crescimento. (NAKAMURA et al, 2004;YANG et al, 2009;MARRE e JENSEN, 2010;LIU et al, 2014;LIN et al, 2015;WATT et al, 2015;MA et al, 2017;SWAIN et al, 2017) A microfluídica é utilizada para obter nanopartículas com maior monodispersão em comparação a métodos tradicionais, que requerem etapas posteriores de purificação para este fim. (SONG et al, 2008;HARTMAN e JENSEN, 2009;YANG et al, 2009)(DITTRICH, 2005MA et al, 2017 segundos, produzindo alta eficiência quântica (35-55%) e mantendo uma faixa de FWHM estreita (26 -31 nm), importante para uma distribuição monodispersa.…”
