In this work we have demonstrated a peptide functionalized cantilever sensor with integrated electrochemical capabilities. Silicon nitride cantilevers with gold electrodes are functionalized with the chelating peptide Cys-Gly-Gly-His (CGGH) to capture Cu2+ ions from solution. Upon binding the copper ion the peptide folds, creating steric hindrance and causing compressive stress in the monolayer, d
Popular Abstract in Swedish När blodförsörjningen till hjärnan upphävs uppstår ett tillstånd av blodbrist, ischemi. När hela hjärnan drabbas, som vid ett hjärtstillestånd, kallas detta global ischemi medan fokal ischemi betecknar att blodflödet är upphävt i en del av hjärnan, som vid stroke. Hjärt- och kärlsjukdomar, till vilka stroke också räknas, utgör idag ett dominerande hälsovårdsproblem i väIschemic brain damage is a common cause of death and disability. A global ischemic insult is usually the result of a transient cardiac arrest while occlusion of cerebral blood vessels leads to focal ischemic lesions, commonly termed stroke. During the last decades our knowledge about the metabolic and cellular events leading to cell death following ischemia has expanded mainly due to experimental
The globally widespread kind of description of vowels by points in the IPA quadrangle with the cardinal vowels as references is very often not trustworthy in its detailed specification. The reasonable interpretation of a dot registration is namely that the vowel quality is very narrowly pinpointed. However, most phoneticians do not have the capacity to judge vowels in this detailed way. Consequent
Consumers are increasingly taking an interest in how their food is produced. Concerns are being voiced that practices that are environmentally harmful, involve maltreatment of animals or exploit poor and vulnerable farmers, should be avoided. The term societal concern has been coined for concerns that are derived from broadly shared values within a society, often entailing an ethical dimension. Th
The design of an ultra-low-leakage latch, suitable for subthreshold standard-cell based memories in 65nm CMOS is presented. Various latch architectures are compared in terms of leakage, area and speed. The most leakage-efficient architecture is optimized by transistor stacking and channel length stretching. The final design is supplemented with a 3-state output buffer to provide low-leakage read f
