  1. 1. Tuning physical and chemical attributes of the synthetic implant poly(L-lactic acid) and its effects on biological stimulation

    University essay from

    Author : Gabriella Sverlinger; Felicia Norman; Nora Othman; Wilma Hämäläinen; Michaela Thyberg; Maja Jonsson; [2023]
    Keywords : Polylactic acid; degradation rate of PLLA; physio- chemical properties of PLA; injectable PLLA;

    Abstract : Poly(lactic acid) (PLA) is a polymer chain consisting of repeating units of lactic acid (LA) used in various biomedical applications because of its biocompatible features. It is commonly used as a subdermal filler and constitutes as the main ingredient in SculptraR, which is a collagen regenerating filler used to treat lipoatrophy of the cheeks or to rejuvenate the skin.

  3. 2. The Potential Use of Degradable Starch Microspheres as a Carrier for Nasal Drug Administration

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Rojda Unal; [2023]
    Keywords : Pharmaceutical technology; Nasal administration; Läkemedel; Pulverformiga bärare; Sfärer; Pulverinhalation; Bärarmaterial; Läkemedelseffektivitet; Pulverteknik; Partikelformulering; Nasal deposition; Biology and Life Sciences;

    Abstract : Intranasal drug delivery is a practical and accessible method for treating localized symptoms as well as achieving systemic drug absorption. The approach takes advantage of the permeability, vascularization, and limited enzymatic activity of nasal tissue, leading to enhanced drug absorption. READ MORE

  4. 3. Influence of starch botanical source on aqueous two-phase system phase behavior and starch microspheres preparation

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Keywords : starch microspheres; acid hydrolysis; DSC; microscopy; potato; barley; corn; pharmaceutical technology; Technology and Engineering; Chemistry;

    Abstract : Background: Starch is a well-studied material, produced by plants in granules to store energy. Starch finds a lot of applications in day-to-day life, in the food and pharmaceutical industry. READ MORE

  5. 4. Examination of suitable material for phantoms used in photoacoustics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Malin Larsson; Klara Wahldén; [2022]
    Keywords : Photoacoustics; PIA; Center frequency spectrum; Technology and Engineering;

    Abstract : A fundamental part of modern medicine is the ability to study and analyze images, especially for diagnostic purposes. A relatively new imaging system is photoacoustics, where laser- and ultrasound technology are combined to create images in a non-invasive way. READ MORE

  6. 5. Constructing an optical tweezers instrumentation and evaluation of trapping stiffness using the power spectrum method

    University essay from Umeå universitet/Institutionen för fysik

    Author : Haoxiang Yang; [2022]
    Keywords : ;

    Abstract : Optical tweezers can trap micron-sized objects such as cells, bacteria, and microspheres, and has become an important instrument for measuring forces associated with various physical and biological phenomena. In this thesis work, I constructed an optical tweezers instrument to trap 2µm diameter beads using a HeNe-laser operating with a wavelength of 632. READ MORE
