1. 1. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

   University essay from KTH/Fiber- och polymerteknologi

   Author : Felix Bogdan; [2023]
   Keywords : Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

   Abstract : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. READ MORE

3. 2. BCP Lithography Defined Arrays of InAs NWs Grown Using MOVPE with Au Seeds

   University essay from Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/Fasta tillståndets fysik

   Author : Björn Landeke-Wilsmark; [2022]
   Keywords : Physics and Astronomy;

   Abstract : In this report we outline a detailed process flow for a quick and inexpensive implementation of large dense arrays of InAs nanowires (NWs) grown in the reactive ion etching/etched (RIE) pores of a SiO2/SiNx mask on top of an InAs/Si(111) substrate. The self-assembled (hexagonally close-packed) pattern of poly(methyl-methacrylate) (PMMA) cylinders in a poly(styrene) (PS) matrix adopted by a linear diblock poly(styrene-block-methyl-methacrylate) P(S-b-MMA) block-copolymer (BCP) was transferred to the dielectric stack (consisting of a ≈10 nm plasma enhanced chemical vapour deposition/deposited (PECVD) SiNX layer topped by a thin atomic layer deposition/deposited (ALD) SiO2 film) using a two-step RIE procedure.

4. 3. Block copolymer-based hybrid nanomaterials for nanoimprint applications

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

   Author : Philip Sellin; [2022]
   Keywords : Block copolymer; Sequential infiltration synthesis; Nanoimprint lithography; Reactive ion etching; Self-assembly; Thermal annealing; Solvent vapour annealing; Nanoprocessing; Nanofabrication; Antibacterial; Technology and Engineering;

   Abstract : In this Master’s thesis project, a block copolymer (BCP) film was used in combination with sequential infiltration synthesis and etching to manufacture a nanoimprint lithography stamp consisting of silicon. The BCP film was designed to contain perpendicularly aligned hexagonally placed cylinders, a pattern that will later be investigated for antibacterial properties after being transferred via nanoimprint lithography to a polymer film.

5. 4. Design of solvent vapor annealing tool and study of kinetics of selfassembly of block copolymers for nano-lithography

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Chujun Wang; [2020]
   Keywords : Physics and Astronomy;

   Abstract : Block copolymer lithography is a very promising candidate for nanoscale fabrication and is economically viable. It provides a high resolution, inexpensive, and straightforward approach to nano-size patterning. In this thesis, fundamental concepts and theories of block copolymer lithography are introduced.

6. 5. Design of Multi-function Polymeric Nanoparticles for Theranostic Application

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Zuhoor Yamani; [2019]
   Keywords : theranostic; polymeric nanparticles; drug delivery; camptothecin; nile red; encapsulation during particle formation;

   Abstract : Block copolymer nanoparticles (NPs) have gained great attention among researcher for various medical application mainly due to their extraordinary optical, chemical, and biological properties. The current thesis presents design of multifunctional polymeric NPs for imaging and drug delivery system (DDS) with an in-vitro study of their participation in drug release and cell viability.
