Schematic diagram of the design of multifunctional nanoparticles-tetrapeptide folic acid copolymers and their potential applications in biomedicine. GFFG and LGPV are the tetrapeptides used as linker molecules (in the single-letter amino acid code:
GFFG = Gly-Phe-Phe-Gly; LGPV = Leu-Gly-Pro-Val) (reproduced with permission from [87], Copyright 2012, American Chemical Society). QD, quantum dot.
In addition, their ability to magnetize allows to rapidly separate the absorbed metal from the parent solution (Keyhanian, Shariati et al. 2016).
However, in the presence of oxygen, MNPs may agglomerate and become demagnetized (Estelrich, Escribano et al. 2015, Predescu, Matei et al. 2018. One way to avoid this is by enveloping MNPs with organic compounds such as surfactants or polymers (Laurent, Forge et al. 2008). ...
Titanium dioxide is a titanium oxide with the formula TiO2. A naturally occurring oxide sourced from ilmenite, rutile and anatase, it has a wide range of applications. It has a role as a food colouring.
Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium.
Nanodiscs are a new class of model membranes that are being used to solubilize and study a range of integral membrane proteins and membrane-associated proteins. From: Methods in Enzymology, 2010.
Oh you can feel it coming....
These people are in big trouble.
And we all know it.

"Justice is not a thing less than the measure, but that which fills it to overflowing.

It exceeds the bounds of mortal requirements.

It endures everlastingly and is not denied one who is entombed.

It passes over with the spirit to bear witness.

It is the great brightener.
It is not a thing bought and sold.

Justice cannot be bartered."
"Be ever above price. One worthy of the greatness you reflect on Earth, one ever above mundane things.

Be not as the ferryman who demands payment before his task is fulfilled, who bears upon the water the man who makes payment and no other.

Yet, the wisdom of our fathers did avail them, whatever is said in the streets today.
They have indeed left a memorial worthy of reverence, and they are not without shrines.
The wise words they spoke have not gone down to be eaten by dust, nor have they been carried away on the wings of the wind.

Co-application of fluorescent quantum dot nanocrystals and therapeutics has recently become a promising theranostic methodology for cancer treatment. We developed a tumor-targeted lipid nanocarrier that demonstrates notable efficacy in gene delivery as well as tumor bio-imaging.
Coupling of aptamer molecules against the EGF receptor (EGFR) to the distal termini of lipid nanoparticles provided the carrier with tumor-specific recognition capability.

We currently believe that instead of “antioxidants,” it is more appropriate to develop “modulators of oxidative stress” because, depending on the condition, it could be more beneficial to reduce or increase the oxidative stress.
