    3D and 4D Printing of Biomedical Materials (BMMs)
    (Institute of Chemistry Ceylon, 2024-09) Siriwardana, A.A. Gayan Kavinda
    Three-dimensional (3D) printing, or additive manufacturing (AM), is a novel technology that fabricates materials on a print bed layer-by-layer. AM manufactures objects with simple to complex geometries using computer-aided design (CAD) models. AM can process various materials, such as polymers, hydrogels, ceramics, glass, metals, and other composites Four-dimensional (4D) printing is considered the next-generation advancement of AM technology, adding a fourth dimension as the time-dependent shape/functional change after printing. 4D printing processes smart materials capable of changing the shape or function upon exposure to certain stimuli such as humidity, temperature, light, pH of the medium, solvent, and magnetic and electric fields. Shape memory polymers (SMPs) play a key role in this context. AM technologies involved in 4D printed BMMs are mainly direct ink write (DIW), SLA, and multi-MJ, targeting applications in tissue engineering, drug delivery, medical devices, and diagnostics. BMMs are broadly defined as biomaterials manufactured or processed to be utilized as medical devices or related components.

    A novel immunoanalytical method for obesity biomarker detection using antibody functionalized silver nanoparticles
    (Institute of Chemistry Ceylon, 2020-09) Abeysinghe,A. A. D. T
    Obesity is a serious health issue related with increased body fat content. Escalating numbers of patients have been reported worldwide throughout the recent past, associated with a high cost in the health care sector. Other than being a disease condition by itself, it also acts as a risk factor for many metabolic and cardiovascular diseases.

    Additive manufacturing (3D printing) of metals and alloys: current trends and future outlook
    (Institute of Chemistry Ceylon, 2024-05) Siriwardana, A.A. Gayan Kavinda
    3D printing, also referred to as Additive Manufacturing (AM), has become a demanding technology in the world which can fabricate three dimensional objects in a layer-by-layer fashion using computer-aided design (CAD) models. AM possesses the unique ability to create complex geometries not conducive for conventional manufacturing techniques such as injection moulding, forging, and machining. Metal 3D printing, one of the increasingly developing areas of AM, started in 1994 with the invention of the first metal 3D printer; EOSINT M250 by Electro Optical Systems, Germany. It used basically a low-temperature alloy for the AM process.

    Advanced Applications of Poly (lactic acid)
    (Institute of Chemistry Ceylon, 2023-01) Dinesh C. Aluthge
    Poly(lactic acid) (PLA) is a biodegradable, compostable and biocompatible polyester. PLA was first synthesized by Wallace Hume Caruthers at DuPont in 1932 via the polycondensation of lactic acid. However, the modern industrial process for PLA synthesis, polymerizes lactide, the cyclic diester of lactic acid (Figure 01).

    Aflatoxins
    (Institute of Chemistry Ceylon, 2021-04) Perera ,K. Sarath; Theeshya Dulmini,D.A.D
    Nowadays, “Aflatoxin and Coconut oil” has become a provocative topic in Sri Lanka. However, aflatoxins (AFs) were first discovered in England, around 1960s, after the outbreak of turkey X disease. In 2012, the International Agency for Research on Cancer (IARC) categorized aflatoxins (B1 , B2 , G1 , G2 and M1 ) as a “Group 1” mycotoxin, which means that they are carcinogenic to humans.
