Elucidating the structure of poly dopamine website updating tools
Bottlebrush polymers with shorter side-chains showed a weaker switching response, and bottlebrush polymers with longer PS side-chains exhibited larger contact angles.
X-ray photoelectron spectroscopy measurements revealed a change in the relative C and O content near the top film surface, consistent with reorganization of the bottlebrush polymer side chains.
To investigate this, we prepared bottlebrush polymers with both hydrophobic poly(styrene) (PS) and hydrophilic poly(ethylene glycol) (PEG) side-chains.
The relative lengths of the side-chains were varied to study the effect of both relative sizes and flexibility of the chains.
Inbrija (previously known as CVT-301) is an inhaled powder formulation of levodopa indicated for the intermittent treatment of off episodes in patients with Parkinson’s disease currently taking carbidopa/levodopa.-tyrosine by the enzyme tyrosine hydroxylase.
It is also the precursor for the monoamine or catecholamine neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline).

The oxidative stress is caused by the formation of reactive oxygen species (H ions in striatum via the Fenton reaction and the intracellular auto-oxidation.
While prior work has focused primarily on measuring the length and stiffness of the backbone, the composition and flexibility of the side-chains may be more important for applications that rely on the interfacial properties of bottlebrush polymers. Schematic for a bottlebrush polymer (left) and for complex bottlebrush polymers with mixed or blocky side-chains (right).
The goal of our research program is to investigate the conformation of bottlebrush polymers in solution and understand the impact that side-chain composition and flexibility may have on interfacial properties, such as contact angles of bottlebrush polymer films or interfacial tension between immiscible liquids.

Contact angle measurements showed that bottlebrush polymers with longer side-chains exhibited a contact angle that depended on the processing history.
