“…Revealing chemical structures of bioadhesives is also possible by NMR, a powerful method used to investigate the presence, abundance and position of atoms (such as 1 H and 13 C). [ 193 ] For example, 3‐(4‐hydroxyphenyl) propionic acid modification of glycol chitosan was verified by the appearance of additional peaks on the 1 H NMR spectrum. [ 111 ] The degree of photo‐crosslinking between MeTro and GelMA was also determined by analyzing areas under specific 1 H NMR peaks.…”

Bioadhesives with antimicrobial properties enable easier and safer treatment of wounds as compared to the traditional methods such as suturing and stapling on a variety of medical conditions. Composed of natural or synthetic polymers, these bioadhesives seal wounds and facilitate healing while preventing infections through the activity of locally released antimicrobial drugs, nanocomponents or inherently antimicrobial polymers. Although many different materials and strategies are employed to develop antimicrobial bioadhesives, the design of these biomaterials necessitates a prudent approach as achieving all the required properties including optimal adhesive and cohesive properties, biocompatibility, and antimicrobial activity can be challenging. Designing antimicrobial bioadhesives with tunable physical, chemical and biological properties will shed light on the path for future advancement of bioadhesives with antimicrobial properties. In this review, we discuss the requirements and commonly used strategies for developing bioadhesives with antimicrobial properties. In particular, we will summarize different methods for their synthesis and will review their experimental and clinical applications on a variety of organs. Advances in the design of bioadhesives with antimicrobial properties will pave the way for a better management of wounds to increase positive medical outcomes.This article is protected by copyright.

“…Integrated optical spectrometers have applications in numerous fields, such as chemical engineering, [ 1 ] astronomical spectroscopy, [ 2 ] biosensing, and bioimaging. [ 3,4 ] Previous approaches to implement conventional integrated optical spectrometers rely on spectral to spatial mapping, including the use of echelle gratings, [ 5 ] arrayed waveguide gratings, [ 6,7 ] digital planar holography, [ 8 ] and photonics crystals.…”

Motivated by applications in mobile optical sensing, ultracompact high‐resolution integrated spectrometers have attracted much interest. Here, a high‐resolution integrated speckle spectrometer, comprising a linear coherent network formed by mutually coupled Mach–Zehnder interferometers and nonidentical microring resonators, is proposed and demonstrated. Deep‐etched grating lines used as mirrors on the edges of the coherent network increase the effective optical path lengths. The speckle spectrometer is realized on a silicon nitride platform, operating at 776 nm central wavelength. The eight‐in−eight‐out linear coherent network provides 64 physical channels. Fine spectral lines separated by 20 pm are experimentally resolved within a device footprint of 520 µm × 220 µm. Compressive sensing is achieved for sparse spectra over a wide optical bandwidth. Up to 600 distinctive wavelength channels can be reconstructed from the 64 physical channels, giving 12 nm operating bandwidth. Both sparse spectra and continuous spectra are well reconstructed experimentally. The integrated speckle spectrometer has great potential for use in future biosensing and bioimaging applications where high spectral resolution is desired.

“…An IR spectrum of the sample is obtained as some of the radiation is absorbed and some is transmitted through. The absorbed radiation is converted to vibrational/rotational energy and the resultant signal obtained at the detector represents the samples' molecular fingerprint, which is generally a spectrum in the region of 4000 to 400 cm -1 (121,126). Throughout this research, FTIR spectroscopy (PerkinElmer spectrum-100) (Waltham, MA, USA) was used to characterise the surface chemical constituents.…”

There are many people I would like to make acknowledgements to, for their help and support throughout this engineering doctorate. Firstly, a special thank you to my academic supervisor Dr Eifion Jewell, a wealth of knowledge, you have always been on hand to share information and steer me in the right direction. Without your guidance, this project would have severely struggled to find a path, especially given the turbulent times of a pandemic and a late move to Asia. I am appreciative of all that you have done, Diolch yn fawr! A massive thank you to my industrial supervisor, Dr.Clive Challinor. You have always been approachable and happy to help wherever needed. You really made the link between academia and industry easy. Thank you for all your encouragement and support, despite our differences in opinion on our national rugby teams! Dr. Christian Griffiths (Chrisy), If I am honest, this entire project would not have been possible without your support. You have always been on hand to assist me wherever needed, sharing your knowledge and being instrumental in keeping the wheels turning on this rickety old bus, hey we even managed to enjoy a few beers on the way. Thanks mate and it's great to be able to call you a friend as well as a mentor now. My mucker (Dr.) Matthew Dodd (Doddsy), it's been a pleasure to graft alongside you mate, at many points we thought it might not happen, but our love of a good pint and continuous moan tenacity to get the job done has surely made it easier! Many others have always been on hand to help when needed. There are too many to list but a big thank you to Dr. Natalie Wint for sharing your expertise and always being there.Dr. Peter Greenwood and Professor Trystan Watson for starting my engineering doctorate journey and helping me establish myself in the early days. Uncle Leighton and the boys at PMRC for always providing a great working environment and helping to get the job done. Finally, a massive thank you to all my friends and family, especially Abbie and my parents who have supported and encouraged me from day one. Without you all, the road certainly would have been much rockier. Spot on.
