• Gold Nanoparticles 納米金市場報價表

  產(chǎn)品介紹：納米金(GoldNanoparticles)的制備方法主要采用還原劑，如檸檬酸鈉，硼氫化鈉等還原氯金酸HAuCl44H2O。氯金酸HAuCl44H2O在還原劑的作用下，可以聚合成一定大小的金納米顆粒，形成帶負電的疏水膠溶液。由于靜電作用而成為穩(wěn)定的膠體狀態(tài)，故稱膠體金(Colloidalgold)。納米金分散在水中：GoldNanoparticlesdispersedinwater粒徑：5nm-100nm濃度：0.05，0.1mg/ml包裝：25ml/50ml/更大粒徑濃度價格（元/規(guī)格）5nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml10nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml20nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml30nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml40nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml50nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml60nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml70nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml80nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml90nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml100nm0.05mg/ml1000元/25ml1600元/50ml0.1mg/ml2000元/25ml3300元/50ml葡萄糖修飾納米金分散在水中：GlucoseofmodifiedGoldNanoparticlesdispersedinwater粒徑：5nm-100nm濃度：0.05，0.1mg/ml包裝：25ml/50ml/更大粒徑濃度價格（元/規(guī)格）5nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml10nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml20nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml30nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml40nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml50nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml60nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml70nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml80nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml90nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50ml100nm0.05mg/ml2800元/25ml3800元/50ml0.1mg/ml3950元/25ml5250元/50mlPVP,聚苯乙烯修飾納米金分散在水中：PVP,polystyreneofmodifiedGoldNanoparticlesdispersedinwater粒徑：5nm-100nm濃度：0.05，0.1mg/ml包裝：25ml/50ml/更大粒徑濃度價格（元/規(guī)格）5nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml10nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml20nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml30nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml40nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml50nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml60nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml70nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml80nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml90nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml100nm0.05mg/ml1800元/25ml2500元/50ml0.1mg/ml2650元/25ml4250元/50ml功能化的納米金分散在水中：(氨基或羧基修飾的)GoldNanoparticlesaminefunctioninwater/GoldNanoparticlescarboxylfunctioninwater:粒徑：5nm-100nm濃度：0.05，0.1mg/ml包裝：25ml/50ml/更大粒徑濃度價格（元/規(guī)格）5nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml10nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml20nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml30nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml40nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml50nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml60nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml70nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml80nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml90nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml100nm0.05mg/ml2500元/25ml3650元/50ml0.1mg/ml3550元/25ml5250元/50ml[詳細]
