15th Workshop on X-Ray Nano-Imaging of Biological and Chemical Systems at PETRA III

“The workshop gives attention to x-ray #microscopy at various PETRA III beamlines with special emphasis on
applications in #biology and #chemistry. Several scientific (multimodal) #XRay #imaging highlights are presented
with focus on the scanning X-ray microscopy beamlines P06, P10 and P05.”

– Diamond-CRLs
– Multibeam #Ptychography
– #Nanoparticle distribution
– #Nanoscopy: #semiconductors

Researchers developed a faster and more precise method to study #nanoparticle #coatings using advanced microscopy. These methods uncover previously unseen surface patterns, helping scientists improve the performance of nanoparticles used in #DrugDelivery and #biosensing.

#Immunogenicity & #biodistribution of lipid #nanoparticle formulated self-amplifying #mRNA #vaccines against #H5 avian #influenza, npj Vaccines: https://www.nature.com/articles/s41541-024-00932-x

Cellular immune responses & #antigen-specific #IgA antibodies in #lungs were also observed. Comparison of sa-mRNA vaccines encoding secreted & membrane-anchored full-length HA revealed that anchoring of HA to the membrane significantly enhanced the antibody and cellular responses.

Treatment with the #nanoparticle reduced #ovarian #tumor growth by more than 50% in human cells and animal models. Women diagnosed with ovarian #cancer may initially respond well to #chemotherapy, but the majority of them will develop resistance to treatment and die from the disease.

“a #nanoparticle #vaccine that includes a fragment of a #SARSCoV2 protein, and delivered it as an aerosol into the #lungs of mice, hamsters and monkeys. This triggered a strong #mucosal immune response — and stymied the spread of SARS-CoV-2 in vaccinated hamsters housed in cages next to one another” https://toot.yosh.is/@yosh/111609209375021433

I’m really shite at explaining things. I shovel info into my brain, note what repeated actions practically I have to take or what to avoid & leave the rest. Explaining is not my gift which is why I love others whose gift it is🖤

His response: (which came really quickly I might add🥰😍)

“No studies have been performed to measure nanoparticle-spike persistence in local or distal tissues”

And no studies have tested whether there’s a blue teapot orbiting Jupiter either (scientist snark) Point is that sure, this could be an issue. Sure, the nanos could also infest your brain, or it could this or that, but that doesn’t invalidate anything. This is FUD, (fear, uncertainty & doubt) - not invalid, but not a valid issue

“ ◦#Novavax expects a low potential for serious unwanted effects and toxicities in neonates, infants, and children” (they don’t know)
◦ “Novavax expects a low potential for serious unwanted effects and toxicities in pregnant women and fetuses” (they don’t know)
◦ “Novavax does not believe there are other special populations which would be more susceptible for serious unwanted effects and toxicities” (they don’t know)”

This is just dumb - who is this guy? Probably a MD, they think they understand science. Science doesn’t find Truth, it discovers truth. It will never be all encompassing. Short answer, we always will know less than can be known, so saying “they don’t know” is just asinine, of course they don’t! They can’t.

Addendum - studies cherry pick, you have to there’s never enough time or money. They studied the big issues, doubtful these are anything which is why they weren’t studied, and for darn sure getting COVID is worse (dumbass)

biodistribution of Novavax nanoparticle-spike has never been done and company “assumes” that it “mostly” stays in local lymph nodes because it should behave like a “conventional protein antigen” (it’s NOT, it’s a nanoparticle)

This looks like scare mongering, he doesn’t say anything but the word NANOPARTICLE is supposed to inspire fear, or something. A null statement.

OK

ALSO contains a saponin-based #MatrixM #adjuvant (40nm #nanoparticle, remarkably stable, held together by saponin-cholesterol interactions” (in rodents causes decreased body weight and red cell mass) – “may contribute to immunotoxicity”

This also is stupid - ask **** about how many times she’s heard **** or I say ANYTHING for certain - we don’t. We qualify everything. Built into techy types, we know nothing is known for 100% certainty - if you want that go join a religion

Yeah that’s probably enough too much to bother with, another technique FUD masters use is loooong, highly detailed posts that look smart and scientific, but it’s part of the advertising. Real scientists cut it short - that’s why there’s a précis/summary at the top. Get the idea in a paragraph and read the rest if you care

-End

Also his response to my Halloween wishes cracked me up🎃

Alas, must continue on that ball gown pattern I started yesterday (wrap apron dress but put anything poufy underneath instant ball gown) hence goblin trick 2 for tomorrow. These goblins & ghouls are so draining

If you're interested in state of the art quantum dot and colloidal semiconductor nanoparticle research, I can only recommended this special issue "40 Years of Colloidal Nanocrystals in JCP" released earlier this year in the Journal of Chemical Physics! Of course it contains an article by myself 😎 #QuantumDots #JournalChemicalPhysics #nanoparticle #PhysicalChemistry https://pubs.aip.org/jcp/collection/1325/40-Years-of-Colloidal-Nanocrystals-in-JCP

"For induction of photothermal assembly around targeted living cells in cell culture medium, infrared continuous-wave laser light was focused onto high-density gold-particle-bound glass bottom dishes exhibiting plasmonic superradiance or thin gold-film-coated glass bottom dishes. In this system, the biofunctional molecules can be concentrated around the targeted living cells and internalized into them only by 100 s laser irradiation"

Scientists at Purdue University created the world's fastest spinning object, which revolves at 300 billion revolutions per minute. Or, put another way, half a million times faster than a dentist's drill.

Hi! #introduction ! I am a #phd student in #chemistry in #vancouver ! I study #nanoparticle #liquidcrystal self-assembly, which has implications in our understandings of #biology nanostructures, #materials chemistry, and #nanotechnology

I’ve been #scicomm ing my #research live on #twitch where I am developing #3dprinting inks made from seaweed and other #biomaterials !

I also interview scientists weekly, so if you are ever interested, let me know! I’d love to have you as a guest!
