Abstract
Respiratory infections in mechanically ventilated patients caused by Gram-negative bacteria are a major cause of morbidity. Rapid and unequivocal determination of the presence, localization, and abundance of bacteria is critical for positive resolution of the infections and could be used for patient stratification and for monitoring treatment efficacy. Here, we developed an in situ approach to visualize Gram-negative bacterial species and cellular infiltrates in distal human lungs in real time. We used optical endomicroscopy to visualize a water-soluble optical imaging probe based on the antimicrobial peptide polymyxin conjugated to an environmentally sensitive fluorophore. The probe was chemically stable and nontoxic and, after in-human intrapulmonary microdosing, enabled the specific detection of Gram-negative bacteria in distal human airways and alveoli within minutes. The results suggest that pulmonary molecular imaging using a topically administered fluorescent probe targeting bacterial lipid A is safe and practical, enabling rapid in situ identification of Gram-negative bacteria in humans.

Abstract
Tris(2-aminoethyl)-amine (TREN), a branched amine, was coupled to planar surfaces of alkanethiol self-assembled monolayers (SAMs) to increase the grafting density of IgG-binding peptide (HWRGWV or HWRGWVG) on gold surfaces. One of the three primary amine pendant groups of TREN anchors onto the SAM, while the other two are available for grafting with the C-termini of the peptide. The ellipsometric peptide density on the SAM-branched amine was 1.24 molecules nm-2. The surfaces carrying the peptides were investigated via surface plasmon resonance (SPR) to quantify the adsorption of IgG and showed maximum binding capacity, Qm of 4.45 mg m-2, and dissociation constant, Kd of 8.7 × 10-7 M. Real-time dynamic adsorption data was used to determine adsorption rate constants, ka values, and the values were dependent on IgG concentration. IgG binding from complex mixtures of Chinese hamster ovary supernatant (CHO) was investigated and regeneration studies were carried out. Compared to the unbranched amine-based surfaces, the branched amines increased the overall sensitivity and selectivity for IgG adsorption from complex mixtures. Regeneration of the branched amine-based surfaces was achieved with 0.1 M NaOH, with less than 10% decline in peptide activity after 12 cycles of regeneration-binding.

Abstract
Extended wavelength analyte-responsive fluorescent probes are highly desired for the imaging applications owing to their deep tissue penetration, and minimum interference from autofluorescence by biomolecules. Near infra-red (NIR) sensitive and self-quenching fluorescent probe based on the dye-peptide conjugate (SQ 1 PC) was designed and synthesized by facile and efficient one-pot synthetic route for the detection of Elastase activity. In the phosphate buffer solution, there was an efficient quenching of fluorescence of SQ 1 PC (86%) assisted by pronounced dye-dye interaction due to H-aggregate formation. Efficient and fast recovery of this quenched fluorescence of SQ 1 PC (> 50% in 30s) was observed on hydrolysis of this peptide-dye conjugate by elastase enzyme. Presently designed NIR sensitive self-quenching substrate offers the potential application for the detection of diseases related to proteases by efficient and fast detection of their activities.

Abstract
A group of self-quenching-based substrates with two fluorescent peptides for detection of trypsin activity was designed and synthesized. The substrates could be easily synthesized using simple solid-phase peptide synthesis techniques. Two fluorescent peptide substrates for trypsin were conjugated to the amino groups of lysine as a branched unit. The fluorescence of these substrates was self-quenched owing to the highly assembled fluorophores on the substrates. The release of these concentrated fluorophores by proteases allows for fluorescence recovery. Self-quenching reduced the fluorescence of the substrates by 64.1%, and the fluorescence intensity was recovered by the release of the fluorophores from the substrate peptides via tryptic cleavage. The kinetic assay revealed that the kcat/Km values of the substrates were almost comparable to those of the standard fluorescent probe, peptide-MCA. The detection limit for trypsin was 111pM, and the calculation of IC50 and Ki values for the Bowman-Birk inhibitor was achieved using these substrates. These easily synthesizable self-quenching-based substrates have the potential to be useful for the detection of other disease-related protease activities.

Abstract
Human neutrophil elastase (HNE) is a serine protease implicated in the pathogenesis of acute and chronic inflammatory disease. Here a series of, internally quenched, single fluorophore fluorescent reporters were synthesised that allowed the rapid, highly specific and sensitive analysis of HNE activity over closely related proteases.

Abstract
A modular approach to the synthesis of trivalent C-glycosidic carbohydrates is described. The approach is illustrated employing carboxylate-terminated C-glycosidic d-mannose, d-glucose, and d-galactose derivatives with different length C1-linked spacer units and also core units with different length linker units attached. The central core scaffold is additionally functionalized via a succinamide-based, conjugatable linker unit, exemplified in an extended multivalent derivative [31] and a pyrene-bearing fluorsecent-labeled tris-C-mannosyl conjugate [33].

Abstract
In the late 1980s independent work by Felgner and Behr pioneered the use of cationic materials to complex and deliver nucleic acids into eukaryotic cells. Since this time, a vast number of synthetic transfection vectors, which are typically divided into two main "transfectors", have been developed namely: (1) cationic lipids and (2) polycationic polymers. In this chapter the main synthetic approaches used for the synthesis of these compounds will be reviewed with particular attention paid to: cationic lipids and dendrimers. This review is aimed primarily at the younger audience of doctoral students and non-specialist readers.

Abstract
The synthesis and photophysical properties of a new terpyridine-based europium(III) chelate (Eu (TMT)-AP3) designed for peptide and protein labelling in aqueous solution phase is described. In order to obtain a stable, easy to handle, versatile and efficient labelling agent, a reactive aminopropargyl arm has been introduced onto the terpyridine moiety. As preliminary biochemical applications the chelate has been 1) efficiently covalently attached onto a representative biomolecule-monoclonal antibody-and 2) converted into iodoacetamido and aldehyde derivatives, and the photoluminescent Eu (TMT)-AP3 was grafted onto cysteine and lysine amino acid residues respectively. These two different solution phase labelling methods yielded original fluorogenic FRET based probes suitable for "in vitro" detection of caspase-3 protease, a key mediator of apoptosis of mammalian cells.
