Hello, how can i expect that UV graph of nanoparticles such as SNPs is accurate and represent good results?

actually my question about the shape of the UV curve when i read articles , i saw different UV graphs some are sharp while other board, although the two values after measure the highest point in...

Hello, dear researchers. I'd like ask about your opinion about this UV graph?

first image for SNPs synthesized by certain plant, while second image is the UV of plant extract without silver nitrate i think the wavelength of SNPs start from 300 to 450 nm? thank you

V R Arun Prakash

What you have been tested in that. it is looks like particles and nano rods .

Reham Hamida

V R Arun Prakash you ask about application of these NPs ?

Dillip kumar Mishra

When you would like to observe TEM of biological samples, better to do at lower voltage or in cryo-mode...so sample preparation would be critical to observe the specimen...apart from that as the scale is in micron, the rod type structures are also large, not in nano regime for sure...i suggest you do some high resolution SEM first then go for TEM followed by diffraction of rods...

Dillip kumar Mishra Thank you

I don't understand this sentence " TEM followed by diffraction of rods... "

i actually i used the SEM at 100.000X

Reham Hamida In TEM there are different mode of operation, one is imaging, another is electron diffraction, and the third either elemental analysis like EELS or texture analysis... so my point is when you do TEM imaging, once you see rod shaped crystalline structures, you could take diffraction on that rod itself to know the composition or type of crystal and its orientations...100X or 100000X? later one you should see detail texture of rod or any shape...
