Summary
Novel composite polymer dots (PDs) offer enhanced fluorescence and stability for biomaterials. These core-shell-shell particles exhibit near-infrared emission and energy transfer capabilities, improving upon pure PDs.
Area of Science:
- Biomaterials Science
- Nanotechnology
- Materials Chemistry
Background:
- Polymer dots (PDs) are recognized for their potential as fluorescent probes in biomaterials.
- Existing PDs may face limitations in brightness, stability, or specific emission properties for certain applications.
Purpose of the Study:
- To synthesize novel, cytocompatible composite polymer dots (PDs) with a core-shell-shell structure.
- To enhance the fluorescent properties, colloidal stability, and emission characteristics of PDs for advanced biomaterial applications.
Main Methods:
- Synthesis of core-shell-shell structured composite polymer dots.
- Characterization of particle morphology, fluorescence emission (near-infrared), and brightness.
- Assessment of colloidal stability and non-radiative resonance energy transfer (NRET) with a model dye.
Main Results:
- Successfully synthesized cytocompatible composite PD particles with a core-shell-shell morphology.
- Achieved near-infrared emission, significantly improved fluorescent brightness, and enhanced colloidal stability compared to pure PDs.
- Demonstrated non-radiative resonance energy transfer (NRET) between the composite PDs and a model dye.
Conclusions:
- The novel composite PDs exhibit superior performance characteristics over traditional PDs.
- These enhanced PDs hold significant promise for advanced applications in biomaterials and fluorescent probing.
- The core-shell-shell architecture is an effective strategy for improving PD properties.

02:10The Nucleosome Core Particle
14.5K
Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

Body:Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

02:39Emission Spectra
76.4K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

02:34Polymers
41.0K
The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.
