"I have used a magnetic nanoparticle with 50 nm size. Even Though it has a small size, it has high magnetic response and re-disperse in aqueous solution well.
In addition to the products, their staff was always polite and helpful! Thank you so much!"

"Dear Nanopartz, Your gold nanoparticle conjugates always look great on the EM grid in my hands!"
Dr. Scott Cohen
Senior Research Scientist
Children's Medical Research Institute
"For our project we needed a very specific type of custom-made magnetic nanoparticles. We tried various suppliers from around the world and assessed their quality and functionality. ONLY Nanopartz was able to deliver the ideal product. Their staff was always helpful, polite, and relentless in their pursuit to make this project work!"
Lodestone Biomedical LLC
"In our multiphoton photoemission experiments, which are extra sensitive to any variations in nanoparticle geometry, we find Nanopartz rods and spheres to be consistently high quality. The photoemission distributions and other properties are representative of the fundamental particle shape, rather than defects, aggregates, or particle heterogeneity. The Nanopartz team is friendly, helpful, and knowledgeable - our go-to for publication-quality commercial nanoparticles."

"Nanopartz is sublime for their broad range of high quality products, which are, as they truthfully describe on their website of excellent quality. The fluorescent spherical gold nanoparticles I'm using in my research are perfect: high density, stable and high fluorescent efficiency, so they're making my nanoparticle microscopy study so much easier. Moreover, their technical support is the best I have ever encountered in a company, very patient and extremely helpful and friendly. Thank you! "

"I have used Nanopartz MUTAB coated gold nanorods and their concentrated bare spherical gold nanoparticles for electrospray applications and have found their products easy to use, and their technical support to be excellent. The solutions have excellent stability over long periods of time and meet the promised specifications closely. Thanks Nanopartz, I look to continue to use your products for many years to come."
University of Minnesota
"We purchased gold nanoparticles from nanopartz before and recommend your products to our collaborators and friends as well, because of the good quality and professional service. So, I want to frankly to say your products are great. Also, we are planning to use such products as standards for comprehensive studies in our lab."
Jiangbo (Tim) Zhao
"I prefer Nanopartz for outstanding product support on customized nanoparticle sizes and conjugations. They are a key supplier in developing novel nanoparticle-based assays."
"We have just received our first Nanopartz product and I must compliment the company for the excellent presentation (loved the gold padded bag) and the comprehensive CoA and recommended storage and handling info. I must also compliment your company on the excellent technical support and great customer service I have been afforded to date. Well done! "
"I have been using the Nanopartz Organic Spherical Gold Nanoparticles in my research and they have worked extremely well due to the moderate hydrophilicity and high concentration. I highly recommend this product."
Arizona State University
"We explored several nanoparticle manufacturers because we were unable to reproduce literature results for our application. One manufacturer recommended Nanopartz because of our desire for a narrow distribution of particle sizes. Nanopartz technical support helped us work through our application problems and suggested custom polymers that readily worked where others had failed. This really impressed us. They always provide quick delivery and helpful advice. We would highly recommend Nanopartz."
Tony Mega, Revalesio Corporation
"... this product (11-30-100 bare spheres) is that we stored in the dark room temperature for almost four years and recently we found out this product still works great for our experiments! Amazing! (we did find some aggregation at the bottom but after we shake the bottom and disperse fine).
Thank you so much!"

"I have been using the conjugates of gold nanorods and gold spheres with the antibody against epidermal growth factor receptor, C225, one of the most powerful anti-cancer drug. The conjugates worked perfectly well on cells, even after long trips and half a year storage."
Dr. Dmitri Lapotko
"Thanks for the 10x45nm Au-nanorods... They are very precise. Our EM pictures indeed show nanorods great in size monodispersity and shape uniformity."
Dr. Periklis Pantazis
California Institute of Technology
"We were previously making our own gold nanoparticles using the commonly used technique of citrate reduction of Au(III). The colloids generated are broadly polydisperse, and we were concerned that our application of these particles in immuno-gold labeling of cells for optical coherence microscopy (OCM) would be utilizing only the large diameter tail of the distribution. We purchased the sampler package of NanoPartz gold spheres (30 nm, 50 nm, 70 nm, 90 nm) and examined each size carefully with dynamic light scattering, OCM, and spectrophotometry. Our measurements indicated diameters a couple nanometers larger than specifications (a result of measurements on the fully hydrated state?), and remarkable monodispersity - within specs. It is clear to us now that our early immuno-gold results were dominated by the largest diameter spheres of our early colloids. We are delighted by the NanoPartz monodisperse preparations and recommend them strongly!"
Dr. Richard C. Haskell

"The scientists at Nanopartz have developed a line of colloidal gold nanorods with extremely high monodispersity in size, shape, and mass. The surfactant layer is highly stable and readily displaced for biofunctionalization. In every test, in vitro and in vivo, these materials have exceeded our expectations."

...By far the most knowledgeable technical support staff I've encountered.
...Incredibly helpful. Honestly, one of the best customer representative experiences I've had!
...Very helpful. I am very satisfied with this company's product. The original reason I purchased particles from them was because they contacted me by chat.
...Excellent technical support. I've worked on nanoparticle synthesis and linking chemistries for 10 years and I learned a lot from this interaction. Give this person a raise!
...Loved it! It was so simple to order!
...was awesome...fast and easy!!! Love it!
...Extremely helpful, and able to answer my questions quickly and accurately. Thanks for all the assistance!
...Very knowledgeable, thanks for the help!
...you are so good!
...The agent was very helpful and thorough in answering my question.
...This on-line chat saved me so much time as I would have been searching the website for an item that I had to order without using website. I've never had an on-line chat pop up for me. The person on the other end was very helpful and speedy.
...Very knowledgeable and willing to work with customer. Chat is an excellent way to communicate. Likely that this ended up winning my business.
...Very quick response and great help!
...absolutely wonderful. made me decide and be at ease about ordering very quickly. very knowlegeable too
... Very helpful in explaining what I needed answered in order to purchase the gold nanoparticles
...This is a very nice feature, and the speed with which the Tech support responded was better than any other vendor I've interacted with offering this service
